[Asterisk-Users] Iax2 channel usage

[Paulo Mannheimer]

Correct me if I'm wrong.

If I have the following setup (a local user dialing through a remote
gateway using IAX2 )...

User -> * server <- IAX connection -> * server -> PSTN

The IAX connection between the servers is completed before the call to
the PSTN is succesfully completed, thus I will be using bandwidth even
for calls that aren't completed yet.

Why does that matter? are you on a metered connection for bytes?
