[SR-Users] automatic string to int conversion for rtpengine flags failed

[Olli Heiskanen]

Hi,

A little follow-up on this:

The problem only happens when I call rtpengine_offer() inside a
branch_route. If I call rtpengine_offer() in the failure_route (after 488)
this conversion error does not happen, but then I get the double sdp issue
indicated here:
http://lists.sip-router.org/pipermail/sr-dev/2014-July/024507.html

The same problem occurs with Kamailio 4.1.5 and rtpproxy-ng. My current
setup uses Kamailio 4.2 (devel) and rtpengine.

If anyone has a way around this, I'd appreciate very much to hear it! This
prevents any calls from being setup.

cheers,
Olli
