Retransmission timeouts

Hi all,

I have a Cisco 8961 device connected to Asterisk 11.3.0 with provider.
Everything works properly, except that I get a set of retransmission timeouts.

Device Debug:

Asterisk SIP Debug:

I’m wondering what could be the cause of those retransmissions. All peers are online.
The device reports sip_sm_ccb_match_branch_cseq : Method index not found.


try to use pedantic=no in config files (or Advanced SIP settings if using FreePbx).

Would also appreciate your Cisco xml config file :smile:
