Thanks. Linephone does support push notifications, problem is I don't have a way to tell Twilio to send push notifications since it's not "their" mobile client. Any idea if you can send push notification to an iOS app that isn't yours? As in: Twilio receives a call, how does it (or my server) send a push notification to to, say, Groundwire?

Acrobits registers the SIP account(s) through their server when push notifications are enabled.

I tried Acrobits Softphone today and it works! Thanks for the help!
