Here's how it works for me: [callcentric-template](!) type=friend context=from-callcentric fromdomain=callcentric.com defaultuser=1777xxxxxxx fromuser=1777xxxxxxx secret=password insecure=port,invite dtmfmode=rfc2833 disallowed_methods=UPDATE session-timers=refuse videosupport=no qualify=no disallow=all allow=ulaw
[alpha11](callcentric-template) host=alpha11.callcentric.com [alpha12](callcentric-template) host=alpha12.callcentric.com [...] On Tue, Apr 15, 2014 at 4:29 PM, Kai-Uwe Jensen <[email protected]> wrote: > So do I need 7 contexts, one for each ip address? >> >> sean >> > > Yes, if what you call a "context" is your peer definition in sip.conf.
