Hi again,
By changing the parameters T1 and T2 in the TM module I managed to have
almost the half branches than before BUT still I get the same Error and I
try to send the call on gateway N.
modparam("tm", "T2_timer", 2000)
modparam("tm", "T1_timer", 1000)
Thanks
Alex

Hello there,
I'm using dispatcher to serial fork a call through many gateways.
For a call to number 2XXXXXXXXX , first a try to connect through gateways
A,B,C after that D,F , after that E,R , after that M,N and finally after
those K,L.
When the call is trying gateway N then I'm getting the ERROR:tm:add_uac:
maximum number of branches exceeded.
I found on internet that I'm exceeding the MAX_BRANCHES:
branch=t->nr_of_outgoings;
if (branch==MAX_BRANCHES) {
LOG(L_ERR, "ERROR:tm:add_uac: maximum number of branches exceeded\n");
ret=E_CFG;
goto error;
}
From a trace I got , I see that kamailio is sending to each destination IP 8 INVITES and
if there is no answer to that is continuing with next destination gateway sending also
there 8 INVITES.
When the number of INVITES is 52 then I get this error.
Does anyone can suggest a way to change the MAX_BRANCHES MAX number ?
Is is important to keep open the INVITEs from the first gateways because is an LCR
scenario and if I get an answer from these gateways is important to complete through
them.
Any help is apreciated
Thanks
Alexandros
