[sr-dev] dlg_bridge problems

[Juha Heinanen]

i tried dlg_bridge, but found some problems.  first, if i didn't define
tm module param fr_inv_timer_avp, i got these kind of errors to syslog:

Jul 22 10:28:53 localhost /usr/sbin/sip-router[15075]: INFO: INVITE <sip:jh at test.fi> by untrusted <sip:controller at kamailio.org> from <192.98.101.10>

Jul 22 10:28:53 localhost /usr/sbin/sip-router[15075]: ERROR: <core> [usr_avp.c:159]: ERROR:avp:add_avp: 0 ID or NULL NAME AVP!
Jul 22 10:28:53 localhost /usr/sbin/sip-router[15075]: ERROR: tm [t_serial.c:430]: setting of fr_inv_timer_avp failed
Jul 22 10:28:53 localhost /usr/sbin/sip-router[15075]: ERROR: Cannot get contacts for INVITE <sip:jh_test_fi at 192.98.101.10:5074;transport=udp>!

nowhere in dialog module docs is mentioned that tm fr_inv_timer_avp
would need to be defined.  is defining fr_inv_timer_avp mandatory in
order to make dlg_bridge to work?

after i defined this avp, and give command

mi dlg_bridge sip:jh at test.fi sip:test at test.fi sip:192.98.101.10:5060

sip:jh at test.fi rings, but when twinkle answers, it does not receive a
refer. 

when sip:jh at test.fi then ends the call, by sending bye, i noticed that
bye goes to sip:kamailio.org:5060 (contact uri in invite) although i
have defined

modparam("dialog", "bridge_controller", "sip:click2dial at 192.98.101.10:5060")

finally, if these issues get solved, is it even in theory possible to
add an "extra headers" parameter to dlg_bridge mi command?
