[OpenSIPS-Users] topology_hinding & load_balancer

[Mirko Csiky]

Hi Bogdan,
Thanks for info!
In fact, the problem did not even exist ! The real problem was caused by
SIPP "pause" command: it didnt work (at all).
So the SIPP uac scenario (invite, ack, pause 20secodns,bye) worked withoud
"pause 20seconds" -> the calls were so fast that TH & LB monitoring with
fifo lb_list  was not possible (lb_load was always 0). That was the cause
that i thought: it doesnt funtcionate at all!
Since we replaced SIPP uac client with real client, the problem can not be
reproduced.
I have another problem now there:
  In incoming INVITE, in Contact header is "src" parameter (the part of
SIPREC). This parameter will be omitted by OpenSips ( with TH & LB ) in
forwareded INVITE ! (xml from multipart will be forwarded)
Can you help here ? Is it possible to recreate it - by some options /
manipulations in routing script ?
best regards
Mirko
