Cisco Analog VoIP

Hello friends,
we have a router 3945 with the following modules - 
Our idea is this - someone is calling a mobile number for example +3598212312 The person is connecting to the number but after that the number redirects the call to the Cisco 3945 then the router calls an ip phone inside it. The point is i think we need additional modules like

am i right and what is the correct module we need. and if i am right how should the connection look like. And what about the router redirecting config? Thanks a lot

Hi svetoslavsimeonov,
Aside from the Cisco 3945, do you also have an existing application in your router such as the Call manager or Unified Communications?You need to have the compatible voice interface card for the 3945 to enable the voice feature.  Feel free to message me directly for further discussion on this.
Thanks,

  • Cisco UCCX VOIP Monitoring Issue

    Hi there,
    We got a customer with Cisco CUCM 8.5 and UCCX 8.5. We have configured SPAN Port VOIP Monitoring for Agent/Supervisor. When Agent is talking, the Supervisor can click on button to hear the conversation. It takes 5 or 6 seconds till we hear the agent conversation.
    I hope someone got any idea why it's taking 5 or 6 seconds till we hear the actual voice.
    Thanks.
    Regards,
    Ysana

    You don't say if this is UCCX or Enterprise
    Make sure your jtapi user has "Standard CTI Allow Call Monitoring" set under permissions.
    If this is UCCX then it should have set that permission when it created the jtapi user, Enterprise you will need to set it

  • WRT54GL & Cisco 7960G VoIP Phone

    Hello fellow Cisco users,
    I use a Cisco VoIP phone, the ubiquitous 7960G IP phone, and have no problem using it with non-Cisco routers.  The phone does not seem to work with the Cisco WRT54GL router under the setup I have as explained below.
    I usually connect my Cisco IP phone directly to my laptop's ethernet port giving the phone a shared internet connection.  This arrangement works fine with two non-Cisco routers I've used.  With the Cisco WRT54GL router however, the phone cannot get an IP configuration, even after opening the needed ports, leading me to believe the problem is likely to be something with the router.  I have also tried setting up a DMZ for the router without success.  The biggest problem is that the phone uses DHCP (which I also prefer) and the DMZ and port forwarding features require I set the phone's IP address.
    I would greatly appreciate any thoughts on how to resolve this.
    Many thanks for suggestions.
    PS:  I forgot to add that the phone works (i.e. receive and make calls)  when plugged via ethernet cable into the router.  Apart from the problem of having an ethernet cable running across a room, this setup also has some features missing like date and time so calls aren't stamped.

    I think your phone is not getting IP address when it is connected to the computer. But when you connect it directly to the modem, it works.
    You can try to upgrade/re-flash the firmware on your router.
    Connect the computer with the Ethernet cable to the router.
    Download the latest firmware from Linksys website and save it on your computer. Open the setup page of the router. Click on Administration tab and go to Firmware upgrade sub tab. Browse the firmware file that you have already downloaded and upgrade it on your router.
    After upgrading the firmware on the router, it is recommended that you should reset the router and reconfigure it. Press and hold the reset button on the router for 30 seconds. Release the reset button and wait for 30 seconds. Power cycle the router and reconfigure it.
    Also try to change some advanced wireless settings on the router. Click on Wireless tab and go to Advanced wireless settings. Change the Beacon interval to 75, RTS threshold to 2307 and fragmentation threshold to 2306. Save the settings.

  • Cisco SPA303 VoIP

    I seem to be going round in circles trying to set up this phone for VoIP, there's so much informatin out there but nothing that explains the set-up I need!
    I have a fixed Broadband line coming through the wall into my office - do I just plug this SPA303 into the phone (SW Socket) or do I still need a Modem and Router?
    How do I get the Admin page up on my computer as I have typed in the phone IP address that it showed in in it's display and it doesn't work?
    Thx.

    Try this:
    Assuming the phone set is still connected to the network, press the setup button, then press 9 to go into the Network setup menu.  Then press 7 to choose whether to enable the phone's web server--it should say Yes if you want to use the web setup utility.
    Then see if you can connect to the web setup page using the phones IP address in your browser.
    I know what you mean about setup being tricky--I have the info from our VOIP provider to point the phone at the provider, but nothing I've found so far in the Cisco docs for this phone to say how/where to enter the parameters.

  • Second telephone number cisco analog adapter

    Hello.
    I have the next situation. I have cisco ata187 and a phone on it. It is registered to cme 9.1. No problems to configure one telephone number per one analog line. But my boss wants also to have the second private number on the same analog phone. How can I do it? If it is not possible on ata187, what adapter do i need?

    Hi,
    If this is the purpose just to receive calls for multiple numbers on a single ATA port you can use number expansion (num-exp global config) but to make calls the extension will be announced to what ever the ATA port is.

  • Cisco 7960 VoIP - 2 simple questions

    Is the 7960 phone SNMP compliant?
    Is the port (on the phone) for an additional PC, also SNMP compliant?

    Hi
    It is a switch port on the phone as you can read in the following link:
    http://www.cisco.com/en/US/products/hw/phones/ps379/products_data_sheet09186a008008884a.html
    But it for sure has limitations and is not comparable to normal switch.
    So you can for sure discover your PC behind the ip phone via SNMP. All you need to make SNMP Queries is an IP connection which is given.
    As i posted bevor i don't think you can query the phone via SNMP because
    i do not know about options to configure SNMP on the phone. I also used a mib browser to query an ip phone...but as expected the phone did not answer.
    Hope that helps

  • Issue defining DN 7965 because using 7965 SD Phone button template on Cisco 7965 VoIP phones

    I am having issue with assigning DN7965 to a phone device. Error message indicates that 7965 is already associated and in use. We have associated phone template 7965SD because most our phones are CISCO 7965. Is there a way to overcome this issue ?

    Hello, All!
    I have continued testing this in my lab and have come up with the following results.
    When setting up a new device, TAPS will generate an error if the DN is already in existence across multiple devices.
    If replacing a device, you must use the same model device or else TAPS will generate an error.
    Unfortunately, based on the above rules, I was unable to utilize TAPS for bulk upgrade of user devices from 7960 model phones to 7965 model phones. However, I have come up with an alternate solution.
    Note: This solution would only need to be used in a scenario where you do not want to assign a MAC address before physically deploying the equipment. The below solution provides the flexibility of creating the phone configurations prior to deploying the equipment without having to have all hardware specifically assigned to a user/DN.
    Bulk Update Cisco Phones without MAC Addresses
    Bulk Admin > Phone > Export Phones > Specific Details (Pull relevant information, DN(s), Description, Owner User ID, CSS, so on…)
    Download the file, change to csv, open in Excel
    Clear contents of “Device Name” field. Parse through and update other fields if needed.
    Save a copy as CSV, upload to CUCM as Insert Phones > Specific Details
    In CUCM, create a Phone Template for import
    Bulk Admin > Phone > Insert Phones > Choose File > Choose Phone Template > **Important** Select Create Dummy MAC
    Run Job
    Once job is completed, all 7965 devices will be created with a BAT prefix and dummy MAC address, check Device > Phone to confirm
    …When ready to activate
    Device > Phone > Search by DN for BAT device
    Open device, change MAC address to new 7965 hardware, check “Is Active”
    Click Save.
    Plug-in 7965 device to network. When the phone comes online and gets past firmware it will pull newly generated SEP config with user ext.
    I hope this helps. I appreciate the communities continued assistance.

  • VOIP over VPN dropp RTP protocol

    We are installing a new 2911 ISR in our office and connecting with a Linksys (CISCO) RV016 VPN router.  These are two small doctors offices that need to have computer, and Voip traffic over a VPN.
    Currently we connect an older RV082 and the RV016 together and have NO issues with VOIP traffic.  If we establish a connection with the 2911 router then we are having an issue with no voice or RTP traffic coming through.  Phones will connect, and dial out, but no voice can be heard.
    The First office is on a Verizon Fios Network with a MTU of 1492. The Network and servers are as follows:
    Remote Office                                                                            Main Office
    Linksys Spa 942 phones
                   |                                                                        
    Netgear 10/100 POE Switch
                   |                                                                        =================
    Linksys (cisco) RV016 VPN                                            |          2911                 |
                   |                                                                       |    POE Module Sw     |
    Comcast Cable Modem                                                  -------------------------------       
                   |                                                                                       |          |
                 VPN                                                                                VPN       |
                   +=======================================+     Asterisk
                                                                                                                  (Call Man)
    Basically we have the Internet coming in from Gig0/0 and routing traffic to multiple outside IP addresses so we are using 3 subs in our configuration.
    192.168.1.X          192.168.2.X          192.168.3.X               192.168.0.X (Remote Group)
    When we connect the old routers (RV016 and RV082) VPN VOIP and Data traffic go fine.   We are using a Term Server on one end, Web Server, and the Asterisk PBX for our VOIP Call Manager.
    So far we connect up the 2911 and the RV016 and have no issues with data traffic.  But the VOIP is dead on the remote end.  No sound.  We did a Wireshark on traffic, and we are getting some 407 errors from the Astersick Host, and a unknown RTP version 1 error message.  THe only thing that we had to do on the RV082 router was port forward UDP 506 and 10001 - 20000 for the traffic, and setup a access rule, but nothing else.
    We are getting traffic on the 2911, but nothing else.  We have excluded the 192.158.0.X traffic from the NAT so not to get into that issue, and have even tried forwarding ports but nothing seems to help.  Is there a good way to route this traffic?  Our bandwidth is pretty fast so I am not sure if QoS is needed, but if so it is not one of my strong areas.  What is the best way to route this traffic through the VPN without loosing the RTP part of the call.

    I put this line in and still not getting audio on the other end.  I will be doing captures tonight from working and non working phones.  I need to get this resolved.  I have spent 3 weeks on this issue and I have run out of time.  Should I use the DEBUG VOIP SIP command for the capture on the router?  I believe this would be the best resolution to the service to see what is going on.  The phones work with a RV016 and RV082 router in place.  All data traffic works fine in sending and recieving calls.
    I have read about all of the articles on Cisco and voip traffic.  We are going to be shutting off the natting on the router to see if I can just get the voip traffic to flow.  Once we get it flowing then I can work on building up the house on a stable foundation.
    At this time, we are routing multiple IP addresses throught the 2911 and have IP NAT OUTSIDE on the G0/0 port and IP NAT INSIDE on the G1/0 Interface, which is a POE Switch Module in the 2911.
    I know that the cisco router wants to act as a call manager, or terminate the SIP traffic on the 2911, but we have a working Asterisk box that handles all SIP traffic.  If there is a way to just forward the traffic there properly, without the 2911 trying to intercept the traffic, that would be wonderful.  I am looking at the possibility of creating dial-peer groups for all of the phones, but really is this needed?  What is so frustrating about the whole situation is that I put in a 5 year old sub $200 router and everything works.

  • UCCX 8 VOIP Monitor Subsystem - Out of Service

    All,
    Upgraded CCX 701(SR5) to CCX 8.0.2 Premium HA enabled. Both Servers were IN SERVICE. Did a Patch upgrade to UCCX 8.0.2SU1. Noticed that VOIP Monitor Subsystem on both servers showing as OUT OF SERVICE. Downgraded to CCX 8.0.2, still get this Subsystem OUT OF SERVICE.
    From RTMT, it shows the following error:
    %MIVR-SS_VOIPMON_SRV-3-VOIP_OPERATION_ERROR:VOIP Subsystem Operation Error: Module Name=LRMConnection.readMSG, A specific description for a trace=erroris: ,Exception=java.io.EOFException
    Anyone kows how to fix this problem???
    Thanks.

    Hi all,
    I had this same problem and similar/same versions.
    Restarting Cisco DESKTOP VoIP Monitor Service (on sub - which had VoIP Monitor Service showing 'OOS') made no impact. I don't think there is any real relationship between DESKTOP VoIP monitor service and VoIP monitor service?
    Anyway, restarted the same service on Pub - no change.
    Tried restarting various sub services including CCX Engine - no change.
    I found I had to restart publisher Cisco Unified CCX Engine, then go to sub and do the same once pub was back to all 'in service'.
    I then found that my sub's 'Log Manager' under 'Cisco Unified CCX Serviceability' had gone to PARTIAL SERVICE.
    I restarted 'Cisco Unified CCX Serviceability' on sub - which had to be done via CLI.
    It appeared to restart no issue - but refreshing the list of services in the GUI several times - it still was in PARTIAL.
    Restarted Sub appliance (bounced the server) from CLI, after reboot - all services were back up and IN SERVICE.
    Thankfully I didn't have to restart my Pub - all services... IN SERVICE on pub & sub
    Resolved.
    PS. No calls were dropped for us.

  • ACS DB Replcation Fails Through Cisco Firewalls w/Skinny Policy Inspect

    We run Cisco ACS v3.3 (Windows) on two servers over our WAN, and replcate the internal databases for redundancy. The problem is that replications fail between the ACS servers and it is because of the default port the ACS servers use to replicate over...TCP 2000.
    Between the two servers are Cisco ASA firewalls running 7.2.2(19). We run Cisco MGCP VoIP phones between the sites as well, which utilize TCP 2000 for call control.
    When the policy-inspect skinny command is enabled on the firewalls, the ACS server replcation breaks, because the firewall sees that the TCP 2000 packets for the DB replication are not VoIP call control packets.
    Is there a way to reconfigure the ACS servers so they use a different port other than TCP 2000? (Registry hack, ini file edit, something???)
    Frankly, it is rather lame of Cisco to implement an already defined port for their DB replication that defined in IETF as a well know port for the skinny protocol. Even worse is that this problem continues to exist into v4.0 as I understand it.
    An no...we should not have to disable the inspect-policy for skinny on the ASA's. :-)
    Any help to qwell my frustration on this topic would be appreciated.
    Thanks,
    -Scott

    Scott,
    If disabling the inspection of the skinny protocol is not feasible, the following
    configuration sample may be incorporated into the firewall configuration so that replication traffic is not affected by the skinny fixup:
    In this example, the ACS servers are at IP addresses 10.1.2.3 and 10.4.5.6.
    #Define what traffic you want inspected:
    access-list skinny_acl extended deny ip host 10.1.2.3 host 10.4.5.6
    access-list skinny_acl extended deny ip host 10.4.5.6 host 10.1.2.3
    access-list skinny_acl extended permit tcp any any eq 2000
    #Create a class map to match the acl
    class-map skinny_map
    match access-list skinny_acl
    #Under the global policy, take the skinny inspection out of the
    #class inspection_default, and add it under our new class
    policy-map global_policy
    class inspection_default
    inspect ftp
    inspect h323 h225
    inspect h323 ras
    inspect netbios
    inspect rsh
    inspect rtsp
    inspect esmtp
    inspect sqlnet
    inspect sunrpc
    inspect tftp
    inspect sip
    inspect xdmcp

  • VOIP VLAN using 802.1q frames causing massive dropped packets

    I have a MBP 2.16 connected via 1Gbps Ethernet to my corporate network. I also have a Cisco 7960 VOIP phone and it seems that 802.1q VOIP VLANs are causing the MBPro's Marvell Yukon Gigabit Ethernet adapter to drop 1326 packets out of 3559. It's absolutely unusable at my office, where my laptop is my main machine. I'm having to use my Compaq N610c to browse the Internet and read e-mail. Apple, please update the driver and save me!!!

    I'd check a few things, are you sure the switch that you are connected to is really at 1000Base-T? If it is a Cisco switch I've seen all sorts of probems with auto-negotiation, I'd try to get your network administrator to "fix" the port at the speed you wish to run your network at (ie 100/1000) make sure the duplex is set correctly on the MacBook Pro (make sure it is set to the same as the switch). Also ensure that jumbo frames are enabled on the Cisco switch and make sure the MTU is set correctly for your network. This involves some tweaking of the ethernet interface in the network preferences of OS X.
    Of course if there are indeed 802.1q problems with the onboard NIC then you could get your network administrator to disable .1q frames on the port that your MBP is connected to, you won't be able to use a "loop through" port on a VoIP phone if the phone relies on .1q trunking, so you'll need a port for the phone and a seperate .1q clean port for the MBP.

  • Problem with Cisco 7925g freezing

    Hi Guys,
    I need some help with the following problem involving our Cisco 7925g VOIP Phones.
    The symptoms of our problem
    The 7925g phone functions perfectly with good voice quality, no one direction calls and no really roaming problems whilst it is active and operating in normal mode
    After an undefined period of time (anything from 20 minutes to 5 hours) the phone’s screen goes black and freezes.
    The phones power button does not function at this stage and requires the battery to be removed and before the phone will restart. No matter how long you wait, have even left the phone alone for a few days, the phone will not restart without removing the battery.
    We are experience identical symptoms on all our 7925g phones and at all our Branches, while the branch have same Access Controllers and Access Points they do have differently configuration Wireless Service Security and Authentication Settings.
    We have even tested a 7925g phone on a completely open SSID with no encrpytion and the phone still experiences the same problems.
    We presume from the symptoms and the diagstonics log obtained from one of the phones, that the problems seems to caused by the memory being full. Any ideas if we are on the right track?

    We also use the Cisco 7921g on this wireless infrastruture and this model seems to be working perfectly.
    We have also updated the firmware of the 7925g to the latest version 1.4.3
    Access Controller:
    Model: H3C WX5002
    Software Version: 2308P11 (Latest Release)
    Access Points: WA2612-AGN and WA2220-AG
    We have logged a support case with the H3C Support Technicians as well, but since all other devices include the Cisco 7921g phone work perfectly, they are battling to find a solution for us.
    Any help in this regard will be greatly appreciated, as currently I have run out of ideas.
    Many Thanks,

    I have thousands of 7925g on that code and we aren't having any issues.

  • Proble to connect Cisco ATA 186

    After I purchased Cisco ATA 186, I connected to Cisco Call Manager 3.3.4, and it worked. I don't know the version of firmware at that time.
    Recently, I used my ATA 186 to test PC to Phone call. It is H323 gatekeeper. So, I upgraded the latest H323 3.01 firmware to my ATA 186. At this point, Cisco Call Manager did not get involved.
    Today, I used this H323, 3.01 version of SCCP, SIP and MGCP tried to reconnect to the call manager, and it failed. It is like ATA 186 and call manager does not know each other.
    How do I fix it ? Should I use the default firmware that came with the device ? Can you tell me what is the default firmware ?
    Product ID is ATA186-I1-A.

    the document below provides information about configuring Cisco CallManager to interoperate with the Cisco Analog Telephone Adapter (ATA) 186 using Skinny Client Control Protocol (SCCP) also known as "Skinny".
