[Freeswitch-users] Homer SIP capture integration

[Karsten Horsmann]

Hi,

yes i was testing homer 3.5 dev.

But since the kamailio world 2014 (which was last week in berlin) homer 3.6
is on the road in dev tree
https://code.google.com/p/homer/source/browse/?name=webhomer_3.6

I did the trick with disable the kamailio capture node log-level to zero.

Also, there is a known bug in FreeSWITCH, that webrtc stuff is not
correctly send via HEP, you see only on call-leg in that behavoir.
But Alexandr will fix that in future.

Btw, cool stuff is sipgrep 2.0 rewritten in C from Alexandr.
