[Asterisk-Users] Trunking Protocols

[Andy Tan]

Hi,

understand that Asterisk supports a variety of signaling protocols like
SIP, IAX2 etc. As a ITSP, which would be the best or most appropiate
protocol to use as trunk to wholesale providers? Know that IAX2 can
conserve bandwidth, but I believe media and signaling are carried with
the same channel/path. That would make off-loading bandwidth utilization
for media impossible. Appreciate any input. Thanks.

Regards
Any Tan
