I've been playing with my new Android phone, installed CSipSimple and happily called my iTalk landline via a 2Talk free Sip account. Works Well - at least for 15minutes per month.

I would love to use the phone via iTalk - but i understand they allow 1 device per account (without going to Asterisk). When i use the iTalk SIP registration - the PAP2T stops receiving calls. 

Ideally the Android phone could use the 3G when not on WIFI, so i'm looking for the best way forward  - is it buying another $10/month VOIP/SIP plan from iTalk or similar ???

ideas - recommendations - siproxd? asterisk?

Thanks, Paul.
