Hey Boo ....Polycom VoIP phone monitoring question

Looking for a solution to integrate/ monitor new polycom phones into cisco works or similar software to monitor hardware issues. I am suspecting that added the phones in between the switch and pc will make monitoring the pc in our current setup impossible....
Is there a MIB solution possibly?
Thanks....

Hi,
what would you like to monitor?
Normally the phones upload their Logs to a FTP/HTTP/TFTP Server automatically at least if they reboot or if the pre-defined Log file size is exceeded.
Only FTP supports append of the files.
Please be more detailed with this request.

VoIP Phones - Testing Latency, Jitter, and Packet Loss

I am having big problems with my VoIP phone connection and I'll try to lay it out clearly here.
The main telephone system resides at Location A (static IP address - see below - xxx.xxx.206.19), which has a network connection of 50MB down/20MB up (i.e., very fast). The VoIP phone configured for that system resides at Location B, which has a network connection of 10MB down/1MB up (i.e., also fast, or at least fast enough "on paper" for a quality VoIP connection). The LAN at Location A uses an Airport Extreme router, which does not have QOS or EF capability. The LAN at Location B uses a D-Link DIR-655 router which does have QOS that is configured properly to direct all traffic to the VoIP phone's IP address.
The VoIP phone at Location B is having intermittent call quality problems with skipping of words, hollowing out noises, jittery conversations, etc. All the inquiries I've made to the ISPs and phone system manufacturer (ESI) suggest that my base Internet speeds are not the problem.
I'm told, instead, that the problem might be latency, jitter, or packet loss between Location A and Location B. This leads to several questions:
(1)     Is there any Mac software that can test latency, jitter, and packet loss? I've looked at Network Utility and it seems to only measure a few things.
(2)     Does anyone see anything in the following Traceroute and Ping results (done twice from Location B to Location A) that looks problematic to VoIP quality?:

(3) Any other ideas on what my call quality problem might be, or how I can tweak it? For example, would putting a DIR-655 router at Location A and enabling QOS really make a difference?
Thanks to everyone, and I hope this is not too long or difficult to understand.

Hey thanks for your reply Yeah im only getting 1 ro sometimes 2 bars reception so hopefully the antenna will beef things up but I think it is what it is perhaps.

VoIP Phone Flaw

Hello,
So I am wondering if the issue with VoIP phones is universal with the LRT224 Phone? Has this problem been reproduced in the Linksys labs? Will this issue be addressed by Linksys Engineers?
Would have settuping up VLAN's worked?

Hey,
Sorry for the delayed response. We have one LRT224 with two WAN Connections and one LAPN600 for the access point. Our network is completely wireless with around 30 devices total (7 IP Phones). We use Cisco SPA525G Phones.
Our VoIP provider is Jive Communications.
I am using the EA4500 and everything works fine on it. The main issue I am having with these phones going through the LRT224 is that phone calls were not coming, and you could not dial other extension throughout the office.
If you have any other questions, please let me know.

VoIP Phone licenses

Hello there,
I'm pretty new to VoIP so please bare with me.. Reading about VoIP phones I've found that you have to buy some kind of license no matter which phone you are using : " All Cisco Unified IP phones require the purchase of a phone user license, regardless of call protocol being used. " Please can someone give me a link or enlighten me a little about them.
Questions :
1. what are these licenses, why should I buy them, how much do they cost ?
2. Is this the only license I'll have to buy to use the ip phone ? Or I'll need some kind of software license too?
Thank you

DLUs = Device License Unit
depending on the phone model how many they use, you need to contact pre-sales or licensing for them
if you don't have the DLUs you cannot add phones
the SKU from each phone entitles you to the necessary DLUs for that phone but DLUs can be purchased separately
you also need a node license to activate the CCM service if 5.x and an extra feature license if running 6.x
you can look "licensing" on cco and will get more info

Voip phone\ BT Broadband softphone rings too quiet...

Hi all
I have a Sogatel Voip phone and the BT broadband talk softphone.
Here is some information on my internet connection.
Connection type Wireless
Wireless Adapter Buffalo Nfinity
Network provider BT Broadband
Router BT Home Hub 2
Encryption type WPA2
Internet browsers in use Chrome and Firefox
Firewall used Zonealarm
The router is in another room but is not too far away.
Signal strength: excellent, 5 bars.
Speed it connects at: 130 Mbps
The connection is generally fine but It rings too quietly. Can anybody help me turn the volume and make it ring loudly because I don't know how to do this.
Thanks in advance.

VOIP phone and airport express

I've been trying to use my old airport express as a remote access point to connect a VOIP phone to my Airport Extreme network. These are both older airports, "pre-N" and from what I've read here, what I'm trying to do won't work.
So, the question is, can I use the new Airport Express(N) to connect the VOIP phone to a Time Capsule(N)? If so, how do I set up the Express? The VOIP phone uses ethernet, and currently works through the LAN on port on my current airport base station.
Thanks.

I've use Netgear adapters and a no name brand from DirectTV. Linksys has them, probably D-Link as well. Best Buy will have several to choose from. About $100-150 for a pair.
Now, your question about whether the "g" Express could deliver an ethernet signal. In normal operation, no. But, if the TC and Express were both configured as part of a WDS (Wireless Distribution Network), the ethernet port becomes active in that event. But...you lose half of the bandwidth on your wireless network. WDS is difficult to configure as well.
The newer Express(n) is much simpler to configure and you won't have the big bandwidth penalty with the "extend a wireless network" setup.
Depending on how your wireless signal strength looks in the office, this will work. But, keep in mind there are far more problems with wireless drops, interference issues, etc. The boards are alive with these types of problems.
I think if it were me, (and this was my business phone), I would go with the ethernet powerline adapters, but make sure you get a return for refund privilege...just in case.

Using existing VOIP phone on FDV

Hey - recently switched to the triple play w/ digital voice. I guess I am lucky after reading some of these comments - the service is working very well using my standard phones and existing wall jacks. i only have one wish - prior to switching, I had VOIP and a great VOIP phone connected to my old router that i really like. I would like to be able to connect this phone to my VZ router and continue to use, along w/the standard phones.
has anyone else tried this or had any luck? Of course talking to tech reps on the phone i get two different answers - so trying to find out the real answer from anyone that has real experience :-)
thanks for any input you may have available!

Howdy, I have at least followed these steps to make VoIP SIP work on the E71 no problems:

Problem transferring calls between Voip phones when the call is originated

Hi,
I have configured a gateway h323 (3640- 12.3) to communicate with Cisco Callmanager 3.3(4).
On the H323 gateway I have installed one BRI interface and one FXS interface.
Inside my network I am using VoIP telephones 7910.
Originating calls in the Voip telephones which destination is the PSTN is working fine;
Receiving calls from PSTN that destination is VoIP telephones is OK also;
Redirecting or doing Hold on calls between VoiP telephones works but..
When redirecting or doing Hold on calls between a VoiP telephone and a call from PSTN I loose the voice stream.
Apparently, all signalling is working fine because when redirecting the call originated in the PSTN from one VoIP telephone to another VoIP telephone, I can see the Calling number ID. Even if I use the telephone keyboard, I can listen the tones, but I have no voice stream.
Please any help will be welcome.
Thanks,
David Costa

I have tried different configurations and now it is working. The problem is that I couldnt identify were the miss configuration was.
Another question is: Can I use a codec with compression between voip interface of h323 gateway and the Callmanager or Voip phones to pass music on hold?
Now I only pass music on hold if I configure G.711 on the voip interface of h323 gateway.
Thanks,
David Costa

RV220W: VoIP phones losing registration and staying offline

Hi all,
VoIP phones connected to a Cloud PBX provider are losing their registration to the Cloud PBX. The router in question is an RV220W.
This started occurring when more phones were added to the site. Phones will boot up, register and then lose their registration within a minute or two.
A larger number of phones of the same model with identical config are connecting through a Cisco 871 router without issues so we know the phones and their configs are good.
SIP ALG is disabled.
The UDP session timeout duration is 120 secs. The phones are set to re-register every minute.
What could be wrong?

TS4009 Is there anyway to establish when my phone last backed up on iCloud if the phone in question is no longer usable?

Is there anyway to establish when my phone last backed up on iCloud if the phone in question is no longer usable?
My wife's phone was dropped down the loo just a day after returning from holiday with all our holiday snaps/vids on it. The phone is dead and only showing on iTunes as in recovery mode. No problem I replied, as it should have backed up on iCloud, however she then advised that the iCloud storage full message had been showing recently but was not sure for how long it had been there. Is there anyway to tell when the last back up occurred or do we have to wait for a new device to be be restored?

In 3 years I never synched my calendar to iCloud for fear I would lose my data. I explained all of this (and the fact that my phone had never been backed up to iCloud or iTunes to the tech at the Genius Bar (I was having wifi issues with my phone which is why I was there so I COULD START BACKING UP) and he assured me synching / merging to iCloud would not delete my calendar events: well, it did. Yes! I have spent hours with apple tech support and had my iTunes account in "troubleshoot " status so the engineers could go into iCloud to see if they could retrieve events. They found nothing. I just don't understand where it goes if it's on the phone? I know there are ways forensic engineers retrieve "lost " data on cell phones. I just thought it might be worth it to post on here and see if there is any hope .

Hey I got my phone stolen yesterday, but it was dead for 24 hours before i checked find my phone so it says offline. I called verizon suspended my service and they said if the person tried to sell it back, or put their number on it, it will get flagged. I

Hey I got my phone stolen yesterday, but it was dead for 24 hours before i checked find my phone so it says offline. I called verizon suspended my service and they said if the person tried to sell it back, or put their number on it, it will get flagged. I was just wondering if i should reinstate my service and try and wait for it to turn back on and then go get it because you need internet for it to track and with the suspended service, it can only track if connected to wifi, but they wont get past my password.

SP-3102 - Unable to make VOIP phone calls after switching router

I had to change the router from Netgear (g) to Belkin N+ (n). Changed the SPA-3102 config to DHCP, it picked up an IP and showed the 1st 3 LEDs lit, status Registered. So, good news.
I am able to receive VOIP phone calls, but not able to make phone calls, it won't dial. I installed slogsrv.exe and got the following log: syslog.514.log. Unfortunately, it's chinese to me.
Please help,
Daniel

Try checking any settings on the old router which you might need to configure also on the new router to get VoIP working like port forwarding, dmz or disabling the NAT. The Belkin might have a feature like NAT which behaves differently so you might need to open up VoIP ports or enable NAT mapping and NAT Keep Alive on the SPA.

DHCP - Cannot add text option for VOIP phones in OES Linux

While working through this, I solved the issue, but decided to post this anyway as it may help others to find these sorts of errors.
I'm working on migrating from NetWare 6.5sp8 to OES11sp2. Client has Shoretel VOIP phones. Existing NetWare-based DHCP has no problem. Option 156 has been configured to give out the required text information that Shoretel phones require.
Problem is that I could not get the OES11 DHCP to run with that option. Nor could I migrate the existing option over - the Migration Tool (in OES11) says it successfully migrates DHCP, but I cannot start the dhcpd daemon. Error is that it failed, and in the rc.dhcpd.log file I see an error:
LDAP Line 26: unknown option dhcp.Shoretel_Boot.
LDAP Line 26: unexpected end of file
LDAP: cannot parse dhcpService entry 'cn=newdhcpservice,o=LIBRARY'
Configuration file errors encountered -- exiting
If I look in the file (created when LDAP reads DHCP config from eDirectory apparently) dhcp-ldap-startup.log I can see the problem entry at line 26:
option Shoretel_Boot "FTPSERVERS=172.30.43.8,COUNTRY=1,LANGUAGE=1,L AYER default-lease-time 259200 ;
This option does NOT show up in the newdhcpservice option when I look at it in ConsoleOne, or DSBROWSE, or DNS/DHCP Management Console.
This option DOES show up in the DNS/DHCPManagement Console if I look at the DHCP (NetWare) tab and look at Other DHCP Options for some of the configured subnets, but it actually has different text from the above, specifically:
FTPSERVERS=172.30.43.8,COUNTRY=1,LANGUAGE=1,LAYER2 TAGGING=1,VLANID=9
Note that it does not have a " character anywhere in the entry. This option is configured as a Global DHCP text option.
Novell TID 7009464 mentions the issue, though not for Option 156. In that TID there is this:
"Situation #2
Migrate a working DHCP server with DHCP options that are of type "Text" to an OES server.
Load the DHCP server service... it fails to load and gives similar errors to the ones listed above."
Under resolution the TID says to delete and recreate the dhcp service object without the text option and it will load. That doesn't work for me as I still get an LDAP error pointing to the Shoretel_Boot unknown option. (I dare not try deleting it from the NetWare DHCP config and risk breaking the client's phone system).
One of the options in the TID to fix this is to re-enter the data using the DNS/DHCP Management Console - but that didn't work.
Here is the answer:
First, the log files are misleading. The error message points to not being able to read the newdhcpservice object entry - but the problem was elsewhere. In fact the problem showed up in the logs even when there were no option 156 entries at all in any object inside the newdhcpservice or the newdhcpservice object itself. The problem existed in the NetWare configuration of the object for one of the dhcp subnets.
Specifically, there was an illegal character in the text entry for option 156 - the # character was in there, like this:
FTPSERVERS=172.30.43.8,COUNTRY=1,LANGUAGE=1,LAYER# 2TAGGING=1,VLANID=9
If you look at the error log entry for syntax error you can see that the option 156 text stopped at the # symbol, and then default-lease-time was appended to the end.
Removing the # symbol got things working.

VoIP phones losing connection randomly for a brief moment

So back story here. Just installed two SG200-26 switches (replacing a unmanaged switch) which are connected together via a trunk.
However my SPA921 VoIP phones randomly have the Mic light flash red (which indicates loss of network connection). It happens for a literally a second and reconnects. When pinging the phone you can see a single ping not getting a reply. It also appears randomly on what seems to be most of the phones but not all at the same time, some may be fine while maybe one or two have the issue. It may have it continuously loosing connection for a brief moments for a while then likewise it my be fine for a while or the rest of the day.
Im looking for some ideas for troubleshooting. So far I tried changing the phone ports to static 10M half duplex instead of autosensing and this seems to not have resolved the issue.
Your help is appreciated.
Thanks
Liam

This was one of the ports I was having a problem with, It went down and up becuase I had done a Admin Shutdown on it. However what is it refering to by 'Aggregated'?

Also brief loss of connection happens even when not going through the trunk
