[Asterisk-Users] IAXTel multiple registers?

[Barton Hodges]

With entries in sip.conf, I can route incoming SIP calls with an
extension specified in the register command:

register => user:pass at fwd.pulver.com/123

The register command in iax.conf does not support specifying the
extension.

If I want to register multiple IAXTel accounts, how can I make them
branch to different extensions or contexts when a calls arrives?
