Hello! I have IP Telephony system on CUCM 7.1.5 and some IP Phones Cisco 7921G:
System Load ID | CP7921G-1.3.3.LOADS |
Version | V04 |
User Locale Version | 7.1.0.1(3) |
Model Number | CP-7921G |
My Wi-Fi network segment is organized on Cisco Wireless Controller 2125 and Lightweight AP`s 1142
In the last time I have a permanent problem with this phones: during conversation in a tube there is a silence on some seconds and at this time interlocutors do not hear each other. After these several seconds communication is restored also interlocutors continue conversation. Please tell me how can I resolve this problem?

Update phone and AP software to begin with.

Please do a wireshark trace and attach it.
That symptom appears to be a timestamp reset in RTP stream.
bye for now,
