We currently have a TAC open for this issue. Thought I would give it a try here.
Situation: We are updating from Jabber 11.5 to 11.7.1. Testing we rolled out to our call center. Randomly the call center staff is reporting that a call will go from normal audio to they cannot hear the caller. The caller can still hear them. This happens with both internal and external calls.
We have Jabber 11.7.1 rolled out to several test groups. The call center is the only one reporting the issue. What is different about the call center:
we have a second call center that we rolled Jabber 11.7 out to. They are different from the call center above in that they have hard phones that are controlled by Jabber and we do not record their phone calls.
At first the issue seemed to be narrowed down to two individuals.
Both had the most reports of issues.
They both used the same Jabra 9400 Duo (stereo headset).
Others, using different headsets report the same issue, just not a frequently
The call starts normally but then moves to one way audio during the call. The only solution is to hang up and call the caller back.
The issue is so random it is hard to troubleshoot. Maybe one or two calls a day or so. Sometimes only once or twice a week.
What we have done?
Put one on a wired headset - was OK during the test period but we had to move back to Jabra
Set one in UCM - built in bridge to off - this worked OK during the test period
TAC has gathered logs from UCM
TAC has confirmed the Jabra headset is on the compatibility list
We have downgraded the two back to Jabber 11.5 - so far so good
We have not replaced the headset. Management is reluctant to do this.
I would appreciate any info and insight. This may halt our roll out of Jabber 11.7.1.
Please let me know if more info or clarification is needed. Thanks All
Hi, I have seen a similar issue with a client getting it on their machines, with the first call on the machine, following a reboot. It's intermittent and not on every machine or even every reboot or everyday.
We are using CUCM 11.5.10000 and Jabber 11.7.1 What version of CUCM are you using?
Have you been able to find a resolution to your issue yet?
Basically our agents will be on a call for some period of time and then the audio on the agent's side will drop out. They cannot hear the caller, but the caller can here them. This goes on for a duration of about 30 seconds. We had a TAC case open when we were running CUCM 10.5 and were told the fix was to shut off the OPUS codec. That is when we upgraded to 11.5 (this past weekend) and disabled the OPUS codec. Unfortunately, we are still seeing the problem.
