[Asterisk-Users] Ringing multiple instruments: sudden cutoff

[Brian Capouch]

I have asterisk set up so that when a call comes in on Zap/1 (to a 
Vonage box) it rings simultaneously both an ATA-186 on the same LAN as 
the Vonage box and, via IAX, a remote S100U on an asterisk server across 
the Internet.

It all seems to work OK, with one unfortunate major exception: when the 
two phones are ringing, if I pick up the ATA on the local LAN here, I 
can talk for as long as I want and everything is cool.  But so far, in 4 
or 5 incoming calls, if I pick up the S100U attached across the net via 
IAX, after a certain variable amount of time (never more than 2 minutes) 
the call suddenly drops, with nothing more than the usual "Hangup" 
messages on the consoles of both instances of Asterisk.

I have some other quality-related problems talking between the ATA here 
and the S100U there, which I will document in a separate mail.

Thanks.
