It appears that VoipSwitch is now offering a generic VOIP SIP client that works on most any VOIP provider. This is based off their revised website information. It cost $20.00. I downloaded earlier today but I have not been able to get it to open on my BB9700. I have a ticket in with their customer service awaiting a reply hopefully tomorrow. If anyone has any luck and can confirm sucess please advise. I don't know why it doesn't open.
Here is their website info:
