[Asterisk-Users] sip registration send out by asterisk

[SW]

Hi friends,

I've noticed that first register message sent by * always get rejected by
the destination sip server. Then * sends a second registration message (
with Autherization section, and that get accepted by the destination host).

Why is this ?

Isnt there a way to tell * to send with Autothorization message the first
attempt ?
