[SR-Users] Doubts with Registration

[Daniel-Constantin Mierla]

never write private emails. They will be simply discarded.

ngrep gets the traffic before the firewall. Do you have a firewall?

start kamailio with log_stderror=yes and debug=5. if you don't see any 
sip message processing, then sip traffic does not reach the application 
layer.

Cheers,
Daniel
