Register packets timeouts

[António Richard Silva <silva.antonio@xxxxxxxxx>]

Hi all,

I have been struggling with a problem regarding the frequency of the initial registering packets.

On RFC3261 it is said that the equipment should repaeta registering after T1 and then T2.

What I am observing is that pjsip is sending packets with the following pattern:

T1 -> 2*T1 -> 2*(2*T1) -> T2 -> T2

I have debugged and print ot some logs and the more strange thing is that on sip_transaction.c, the reschedule timer is configured to the correct value and the logs in fact show that the retransmit packet if after T2sec, nonetheless in between there are 2 more packets that I don't know which module is re-transmitting the register packets.

Any help would be appretiated.

Kind Regards
