[SR-Users] Problem with REGISTER retransmissions

Thu Sep 22 12:46:34 CEST 2011

Ok Daniel, thanks again. We'll update our server as soon and as safely 
as possible.

The output you wanted is here (version 3.1.4). The AOR is 
"phoenixMaster at sip.aeq.es". The commnad has been executed with a 1 
second period. The CSeq of the retransmitted REGISTER is 4627 occurring 
at 12:36:55.

Cheers.

Alejandro.
