asterisk users - Mar 2005 - Multiple outgoing calls through VOIP providers

Trying to get some straight info from the VOIP providers is difficult. 
Say there's a small Asterisk switch and it's registered with Broadvoice 
or LiveVOIP or someone. There are a couple of people using the switch, 
one is on an outgoing call with the VOIP provider. What happens when 
someone else initiates another outgoing call through that provider on 
the same SIP registry? Does * know that the SIP account is busy or does 
it dial out anyway? Does the provider care? Do I establish a call group 
of SIP accounts like I would of Zap trunks and Dial/g1 ?

Depends on the provider.  voicepulse allows up to 4 outgoing and 4 
incoming connections on their connect service, which is iax2 by the 
way.  Highly recommended for multiple calls.  I imagine if I hit that 
limit, the call will fail and look for the t or i extension and run that.

I can only advise that you try it and watch the console.  It's usually 
pretty clear what's happening.  You can then script the extension that 
it's trying to jump to.

I'm a provider and you can have hundreds of calls going at the same time 
with the same account. I don't know how Asterisk does it but I would 
assume it can handle the same.
