Cisco 7925 and Singlewire PustToTalk no voice

Hello,
     I am in the middle of implementing a Singlewire PushToTalk system in a wireless network with Cisco 5508 WLCs and Cisco 7925 phones.
    I managed to configure everything and PTT works with the exception that from time to time there is a indication on the listening side and a beep sound, but there is no voice and the listening side doesn't hear anything. There is no logic when it happens and when it doesn't. The problem appears approximatelly 1 of every 15 attempt in one session.
    The firware of the phones is the latest 1.3.4 and the PTT software is the latest, too.
    If anybody has any idea what can be the reason I will appreciate any advices and hints.
   Greets,
        Georgi

Cisco 7925 Wireless Phone Wireless Auto Config

Hello all,
My rehabilitation hospital is located right next to a large hospital connected by a catwalk. We have had 3 incidents where our RTs have gone over to the hospital next door for patient MRIs and our Cisco 7925 wireless phones are being configured with that hospitals wireless profile. The RTs are saying that no one from that hospital are manually configuring the phones to be on their wireless network so they can be used while off our wireless network. We're thinking that the RTs are putting their phones down and picking up the other hospitals 7925s by accident before leaving. My question to you is...Does the Cisco 7925s have an auto configuration tool that will automatically pick up on a particular wireless network and automatically configure itself and register with a Call Manager? Thanks!
Regards,
Terence

Leo and George,
Exactly! It makes absolutely no sense. All our Cisco 7925 phones are manually configured for our voice VLAN for our wireless network infrastructure. It's the only profile I've configured for those phones. I spoke to the other hospitals IT personnel and was advised that they use a wavelink server that sends the configuration to their 7925s after they have been entered into the server. The only explanation I can come up with is that our RTs are sitting our phones down, doing whatever they need to do over at the hospital, then picking up the hospitals 7925 thinking they're picking up ours. Another thing to note is that when I reconfigured the phone to be put back on our wireless, the phone performed a firmware update and then registered to our Call Manager.

Cisco 2960-X / Singlewire / Atlas Multicast Issues

Atlas and Singlewire are blaming the 2960-X stating that it is blocking the multicast traffic and this is why the Atlas IPS-ZCM cannot register because the SLP packets are not reaching the Singlewire server.
Already worked with Cisco TAC and they state there are no issue on the 2960-X. But based on the wiresharks from both devices, I do see the SLP request leaving the Atlas device, but I never see it hit the Singlewire server. Both devices are physically on the same switch and on the same vlan.
I have enabled and disabled IP IGMP Snooping globally with no success.
Any suggestions on a fix would be appreciated.
Atlas devices is on port 1/0/43
Singlewire is a VM running on BE6K server on port 1/0/47

Cisco 804 and ISDN problems

I've got a problem that I could use some input on. We have several
Cisco 804 routers that we use for our teleworkers at home. They have
standard PC's that connect to the ethernet interface on the router
and to a Siemens phone with Optiset teleworking adaptor via 9 pin
serial cable and COM1 port on the PC.
On the router, we are running the BRI0 and Dialer1 interface with
PPP multilink. I can get the router connect to our DC here in
Seattle without problem. The problem comes while trying to use
Siemens callbridge.
With the phone connected to POTS2 and not signed into callbridge, I
can pickup the handset and get a dial tone. I then sign into
callbridge which takes the phone (via the serial cable) and connects
it to a server (over Ethernet) here in our office in Seattle. This
succeeds, however when we then go off hook while signed into
callbridge, we don't get a dial tone.
I should step back for a second and state then when not signed into
CB, and pick up the phone, we'll see the router release BRI0:2 and
give it a voice (dial tone) signal. When signed into CB, this does
not happen. We are also seeing the error below:
ISDN BRI0: isdn_is_bchannel_available: No Free B-channels
I've got ISDN Events and q931 debugging on and am not seeing anything beside the error above that would point to a problem. Cisco has a 20 page debug all that they are going through to search for an answer.
Any chance that anyone has worked with this before?
Thanks,
James

I would say that this is because the router is connected over 1 b channel to your seattle office and then when you log in with your callbridge you are using the second b channel so when you goto use the phone the router simply has no more b channels to use to carry your phone call which is why you get no dial tone.As BRI ONLY HAS 2*64Kbits b channels and 16Kbits d channel(signalling)

The SIP Media Inactivity Timer feature enables Cisco gateways to monitor and disconnect VoIP calls if no Real-Time Control Protocol (RTCP) packets are received within a configurable time period.
When RTCP reports are not received by a Cisco gateway, the SIP Media Inactivity Timer feature releases the hung session and its network resources in an orderly manner. These network resources include the gateway digital signal processor (DSP) and time-division multiplexing (TDM) channel resources that are utilized by the hung sessions. Because call signaling is sent to tear down the call, any stateful SIP proxies involved in the call are also notified to clear the state that they have associated with the hung session. The call is also cleared back through the TDM port so that any attached TDM switching equipment also clears its resources.

Call your phone carrier - that's a problem for them to resolve.

Once it's in recovery mode, everything on the phone is already gone. If you've been backing it up and syncing on a regular basis, it should restore just fine.

Routing issue between Cisco Nexus and Cisco 4510 R+E Chassis

We have configured Cisco Nexus 7K9 as core and Cisco 4510 R+E as access switches for Server connectivity.
We are experiencing problem in terms of ARP learning and Ping issues between Cisco Nexus and end hosts.

Hi,
So you have N7k acting as L3 with servers connected to 4510?.
Do you see the MAC associated with failing ARP in 4510?. Is it happening with all or few servers?. Just to verify if it is connectivity issue between N7k and 4510, you can configure an SVI on 4510 and assign address from same raneg (server/core range) and perform a ping.
This will help narrow down if issue is between server to 4510 or 4510 to N7k.
Thanks,
Nagendra

how to configure one dsl connection and one public ip in cisco router and map to one interface for using exchange server

Hi ,
Have you got any additional public IP Address from your service provider , If yes on router you can have static route for those additional IP Address pointing to your ASA outside interface .
Accordingly you can configure NAT

Voicemail is through your carrier and on their equipment.
It's function and features is set by them, not your phone.

Cisco wireless and Apple Mac woes

Hello all,
I've been working with Cisco wireless and WLC's for a couple of years now but the recent onslaught of Apple Mac's is giving me heart burn. I've seen this at numerous sites now and need to throw it to eht community for guidance.
Basically we have had a number of instances where the Macs just fall off the wifi. Sometimes it's when they wake from sleep and other times when roaming between AP's (1131s with same SSID's). Our standard install is WPA2 and per ap local authentication. PC's work fine and never an issue.
We have completed a survey with a spectrum analyser and no RF interefence is present nor errors on the radio interface.
Questions:
- Is there a preferred Cisco config/setup for Mac's to work reliably? I've heard loads of rumors but nothing concrete and nor can I find anything specific.
- Should I be setting up WDS in case there is an authenticating issue.
- For those who are Mac gurus and happen to be reading. What Mac options we should look at?
This has all come to a head because the clients IT company who recommended the Macs (different from us doing the network infrastructure) are insisting that the problem is Cisco incompatibility and that we should rip out the Cisco kit and install airports (what tha!!!).
Thanks in advance for any pointers.
For those who like a config here it is .... Vanilla stuff really

Yeah!! even i have come across multiple issue with MAC and Cisco.. these are the below settings which i normally do on the cisco gears and most of the times this solved the issue..
on the IOS AP disable Aironet Extentions and set the poer local and ofdm to max
no dot11 extension aironet
power local cck max
power local ofdm max
end
On the WLC, disable Aironet IE..
lemme know if this answered your question..

The difference of the IEEE802.1x Auth between Cisco Routers and Catalyst switches

Hello
I am investigating the difference of the IEEE802.1x Auth between Routers and Switches.
Basically dot1x auth is availlable on Catalyst Switches. however if I want to check to
PortBased Multi-Auth , MAC address Auth and any certification Auth with this feature,
Is it possible to integrate into Cisco Router such as Cisco 891F ?
In my opinion Cisco891F is also available to use basic IEEE802.1x but if it compares with Catalyst switches such as Cat3560X
I think there might be any unsupported feature on Cisco 891F.
I appreciate any information. thank you very much in advance.

Many time in interviews asked comaprison between cisco routers and switches that i was answerless bcoz i dont have much knowledge about that.Can anyone provide me the compariosin sheet of the same.how are the cisco devices differ with each other how much Bandwidth each routres support and Etc...
Ummmm ... The most common question I get is "what is the difference between a router and a switch".
However, if you get a question like this, then my impression to this line of questioning are:
1. The candidate they are looking for has in-depth knowledge of routers and switches. And I mean IN-DEPTH!;
2. They are not looking for a candidate. They just want to stroke their ego. There is not alot of people who can give you the "names and numbers" of routers and switches at a snap of a finger. And if you do happen to know the answer, then and there, then expect a tougher follow-up question.

Urgent!!! Cisco ACE and asymetric routing assistance needed

I am wondering if someone can give me pointers on the cisco ACE
and asymetric routes. I've attached the diagram:
-Cisco IOS IP address is 192.168.15.4/24 and 4.1.1.4/24
-Firewall External interface is 192.168.15.1/24,
-Firewall Internal interface is 192.168.192.1/24,
-F5_BigIP External interface is 192.168.192.4/24,
-F5_BigIP Internal interface is 192.168.196.1/24 and 192.168.197.1/24,
-host_y has IP addresses of 192.168.196.10/24 and 192.168.197.10/24,
-Checkpoint has static route for 192.168.196.0/24 and 192.168.197.0/24
pointing to the F5_BigIP,
-host_y is dual-home to both VLAN_A and VLAN_B with the default
gateway on host_y pointing to VLAN_A which is 192.168.196.1,
-host_x CAN ssh/telnet/http/https to both of host_y IP addresses
of 192.168.196.10 and 192.168.197.10.
In other words, from host_x, when I try to connect to host_y
via IP address of 192.168.197.10, the traffics will go through VLAN_B
but the return traffics will go through VLAN_A. Everything
is working perfectly for me so far.
Now customer just replaces the F5_BigIP with Cisco ACE. Now,
I could not get it to work with Asymetric route with Cisco ACE. In
other words, from host_x, I can no longer ssh or telnet to host_y
via IP address of 192.168.197.10.
Anyone knows how to get asymetric route to work on Cisco ACE?
Thanks in advance.

That won't work because ACE uses the vlan id to distinguish between flows.
So when the response comes back on a different vlan, ACE can't find the flow it belongs to and it drops it.
Even if we could force it to accept the packet, ACE would then try to create a new flow for this packet and it will collide with the flow already existing on the frontend.
You would need to force your host to respond on the same vlan the traffic came in.
This could be done with client nat on ACE using different nat pool.
