[asterisk-users] sip trunk failing to register causes sip phones to become unreachable

[John Cahill]

Hi,

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?

Thanks.

Regards,
John
