I seem to be going round in circles… I am trying to use dlg_bridge() from the dialog
module to establish a call between two SIP endpoints. I have tested with Snom phones and
linphone soft phone with the same result.
I get an outbound call to the first (from) end point, I answer the phone… and then
nothing obvious happens.
I can get this same result when using kamcmd or from within the kamailio.cfg. For example
using kamcmd:
kamcmd dlg.bridge_dlg sip:105@mykamailioip sip:106@mykamailioip sip:mykamailioip:5060
I expected this to send an invite from "controller" via my KamailioIP to my
registered local subscriber 105 (from), and then send a re-invite to 105 so that 105
creates a call leg to 106 (to).
The kamailio.cfg is pretty much the default. I am running 4.2 and rtpengine to proxy the
RTP streams.
Not sure if it is necessary or useful but I call setflag() at the start of the
request_route() to set the Dialog flag. What else should I have included in the
kamailio.cfg to make this work?
Also is there any way to control the SDP in the initial invite from dlg_bridge. By
default I see RTP/AVP, with alaw and ulaw…. I’d like to offer RTP/SAVP swell or instead of
RTP/AVP.
Thanks
