Can you set up more than 1 SIP provider

[mlindner]

Can a pro version, hosted or self hosted support using SIP Trunks from more than one vendor at a time ? I want to be able to specify certain calls to go out though a particular provider and have different phone numbers come in from different provider(s).

Yes, this is possible, and you can create outbound rules to pass calls through different VoIP providers.
