Sip Trunk Failing To Register Causes Sip Phones To Become Unreachable



I have only seen this problem when using SIPgate SIP trunks which actually "register". If the ADSL connection goes down that the sip trunk uses, the sip phones registered locally become unreachable. This happens on any 1.6.x or 1.8 version of asterisk I've tried. Is there a work around that doesn't involve putting an opensips server between the asterisk server and the sip trunk?


Regards, John

Forcing SIP trunk matching order?


I have a bunch of different customers on an Asterisk Box (the PBX).
This Asterisk Box is behind another Asterisk box that provides a PSTN
Up to this point I've been using IAX between the 2 Asterisk boxes, but
I would like to use SIP instead.
After doing some testing I have the following issue. If customer A calls customer B, but the call goes out through the PSTN
and comes back in, the call is rejected at the PBX because it wants

better timing source for an asterisk gateway


Hi, I have to make an asterisk gateway in front of several other asterisk.
This gateway will essentialy be used for outbound call.
This gateway will be connected to other asterisk by IAX trunk, outbound
call will use SIP trunk (voip provider or patton isdn).
I have a TE220BF available than i can use for dahdi timing source. Is a
good idea, or this will give me zero benefit for timerfd timing source
(will host this gateway on debian squeeze or centos 6.2) ? Thanks.
