[asterisk-users] IAX implementation question

[Alejandro Cabrera Obed]

People, I've setup Asterisk in a basic mode with SIP protocol. In the
future I wanna connect several offices each one with an own Asterisk
server, using IAX because I read it has no firewalling problems using
just one UDP port for control and data -aming other advantages- . SIP
has NAT problems I know.

Do you recommend the use of IAX instead of SIP for users and among
several Asterisk's ???

Does the IAX implementation take any extra considerations than SIP ???

Any initial guide for IAX - Asterisk configuration ???

Thanks a lot,

Alejandro
