[Asterisk-Dev] Nat

[harry gaillac]

Hello

What do you think of this mail to make it possible?
If an asterisk developper could advise me .


I don't know this part of Asterisk code sufficiently,
but you would need 
to hire a programmer for this anyway. Maybe you should
post a bounty 
into the Asterisk-Dev list I am sure one of these guys
would not mind 
picking it up if you place a bounty.

Another option that is obvious (I don't know SER) is
for SER to connect 
to Asterisk a if it was standard SIP phones - just
thinking loud...
