[Kamailio-Users] ERROR:tm:add_uac: maximum number of branches exceeded

[alex pappas]

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
