Problem with cisco ip phone 3905, cipc-Admin-fmr.8-6-5-0

[anthonio1]

Hi guys,

I have an issue with cisco ip phone 3905 and cipc-Admin-fmr.8-6-5-0(softphone)

1. With the 3905, the main problem is with audio. A user cannot hear the person on the other end or vice versa.

I upgraded the firmware from APP3905.9-4-1-0 to APP3905.9-4-1SR2-2 and the phones havent picked the new firmware. The users are still experiencing the problem.

2. For the softphones, they sometimes have the same issue with the 3905 or just hang. When this happens dialing is impossible.

Please advice.

Hi,

Please restart the TFTP service on the TFTP servers after you installed the new firmware and then reset the phones so that they can take the new firmware.

For CIPC ( softphone ) you can generate a CIPC problem report that is available in Programs menu of Windows when the issue is reproduced. It can be analyzed to see if there are any issues with the client. Else, generally the no audio issues can be due to routing or firewall issues on the network.

Thank you very much Gogna for your speedy response. I have generated the CIPC problem report. Are there specific files that I should check?

[Manish Gogna]

You should check the Trace file which corresponds to the time stamp when the issue was experienced. Please remember that for one way / no way audio issues the cipc problem report is just a small part of the troubleshooting, ideally you will need simultaneous packet captures from PC to check signaling and RTP flow.

Is this just from a single IP phone?

Is the phone inside the network, i.e. not using something like a VPN?

Do you have other 3905 models which work fine?

Audio issues are often to do with firewalls or routing.

Thanks
