We recently upgraded to CCM 4.1.3SR1 and have been experiencing an issue with the Meet-Me bridges. An internal user will intiate the bridge and other internal users can use the bridge without fail. A user who is calling in from the PSTN via our router can participate for awhile but after about 10 minutes the remote user no longer hears audio but the internal users are able to hear him/her. The gateway is using MGCP and the version of code is 12.3.14.T5. Anyone know a reason why one-way audio would kick in after 10 or so minutes?
It happens on both meet-me and ad-hoc conferences.
Other calls do not experience this issue.
In Chicago we have 10 digit dialing so the calls were actually local but the 10 digits appear but the issue has appeared for both local and long-distance calls
We have been able to reproduce the issue almost every time and it takes at least 10 minutes of conference call time before the issue appears.
While I do see the statuses you are talking about and I have had my issues with various phone companies we have been using the same PRI line for over two years without this issue. Something I did not mention in the first post is we also upgraded the CCM server and the original server had a DT-24 card contained in it that we were using for the gateway. When we upgraded the server and software we also installed the 2801 as a gateway. I can't think of anything that we would have had to provision specifically for the DT-24 card but thought I would mention it.
Do you need any more traces or information from me?
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
