My users have been complaining of constant disconnects the last week or so. I'm also getting User disconnect emails to my admin account from the PBX. Here's the email content - any ideas what would cause this?
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
One side of the call between sip:442095058@sbc.voipdnsservers.com;user=phone and sip:9417804421@sbc.voipdnsservers.com;user=phone did not receive media for 2.5 s and the other side of the call disconnected the call. The address of the other side was 76.79.172.170 (User-Agent=Linksys/SPA941-5.1.8). You may use this email as hint for a potential problem. The SIP messages are attached.
