These softphone applications conform to IETF SIP standards so that it should work fine with other standard SIP clients. In addition, it has many other advanced features such as voice encryption and NAT Traversal etc. Unfortunately, X-Pro, XTen softphone for PPC is not free, and one has to buy from their website:
