OK Im at my wits end here…
First my system
1 x Sipstation trunk (see details below)
1 x Sangoma PCIe card 4 port with three analog lines
I have the first outbound path the SIPSTATION trunk then the POST lines
Calls will randomly drop after about 20 seconds. I see a number of posts with the “20 seconds” in there but nothing is fixing it. What I do see is something odd, when I watch the system and a call comes it I see two (2) channels being used. If another call comes in that number will jump to 10! Seems very odd as its only one more call.
I ran a tcpdump and while I have not captured a dropped call yet (its pretty random) I do see odd entries like “FROM: SIP# Protocol: SIP Packets 7 STATE: REJECTED” I have to idea why its rejected. The odd part is calls are working even when I see that. Again I have NO captured a dropped call.
Im using G.711 across the board, with GrandStream GPX1450 phones. Nothing special about the system pretty much out of the box with the normal settings.
I also saw the same issue with a different trunk provider so it seems to be either something on my end, or the configuration.
Any help would be MUCH appreciated, and my next move is to go direct to the Schmooze support but wanted to toss this out to try and get it sorted if possible!
