Hi,
I’ve notice a problem registering to my sip provider after upgrading * from 1.2.09 to 1.2.11
My provider is skypho and is registering server is voip.eutelia.it (ip:195.62.225.244)
I’ve used this reg string: register=number:secret@voip.eutelia.it/ext
but registering allways goes to time out.
With sip debug on ip i’ve discovered this:
REGISTER 12 headers, 0 lines
REGISTER attempt 1 to number@voip.eutelia.it
Reliably Transmitting (NAT) to 195.62.225.244:5060:UD
with fd -1
REGISTER sip:voip.eutelia.it SIP/2.0
Via: SIP/2.0/UD myip:5060;branch=z9hG4bK65d9ff21;rport
From: <sip:number@voip.eutelia.it>;tag=as64df631d
To: <sip:number@voip.eutelia.it>
Call-ID: 7332c52d024b40144e1bd7fc072e47da@10.0.0.137
CSeq: 102 REGISTER
User-Agent: asterisk
Max-Forwards: 70
Expires: 300
Contact: <sip:number@myip;transport=UD>
Event: registration
Content-Length: 0
Immediatly i’ve notice that the transport was UD instead of UDP
Changing the reg string to:
register=number:secret@195.62.225.244/ext
so with the ip instead of the domain name the register goes to goal but still not be able to recevie calls
Now it’s work but i don’t know how i made it 
I’m asking you: “perhaps there is a bug with sip stack?” i’ve searched on this forum but i’ve find nothing about that
bye
