Hi

we got complaints from 2 different users. they scheduled online meeting and when a participants try to join from phone, it getting joined and after some secs its giving the below message and the call disconnected.

"sorry i am having trouble accessing the system right now. please try again later. good bye"

As of now we got two similar complaints. both are different meetings.

when the participants join using Lync audio from their PC, its working. problem is only when they join from phone.

so we took mediation server log and we found the below

i compared the logs with working and non-working meeting and i found that, in the non-working meeting after "MediaSessionAgent.set_connectivityEstablished" action "proxycall.onproxystatechanged" event is occuring

but in working meeting scenario after "MediaSessionAgent.set_connectivityEstablished" action "Mediationcall.constructor" action is occurring.

in both of the scenario the session went via my Lync edge server.

Please help

Did you join the conferencing from Lync phone?

Please check if you can join the conferencing from a mobile phone number.

Please check if you can dial the phone number from the conference.

Collect some log files on Lync Edge Server and Front End Server.

I am having the same issue with all of my calls. Has this been resolved? what log files will help in the troubleshooting of this?
