I am using this as a FXO adaptor. It seems that if the outside caller puts me on silent hold, the call drops after 60 seconds. I am using Asterisk, and have checked sip session timers, and rtp timers, and increased them all to 3 minutes, but there is no change in the dropped calls.
I have noticed there is a TimerT2 and timerT.... so many - but there doesnt seem to be any documentation on this parameter, do I need to change one of these to increase an rtp timeout issue, or what might be causing the hangup?
Do you mean silences on calls coming in on the 110's PSTN line port? Management, Physical interfaces, Line port, PSTN Disconnect Detection has DetectFarEndLongSilence (default is 'yes') and SilenceTimeThreshold (default 60 seconds).
duh - I was looking in the sip area, when it was the line, thanks.
