Today, I have customers that connect to a Sutus BC200 via a $6.95 SIP client that tunnels via PPTP from any wireless network back to their cost effective PBX so they can make local calls on their wireless phone without Cell minutes. There is a story on it at pbx2sip dot com in their blog.
It's a compelling business proposition to companies trying to reduce their cell phone bills for their mobile workforce. Imagine a salesmen that travels out of country - he finds a hotspot, turns on his client, and calls the office or home as a free call.
I think that RIM is missing an opportunity here, I think history has shown over and over again that closed standards do not drive good business.
There are clients on their way, if you find one, please post it hear, I'd love to try one out before I have to give up my Blackberry due to none being available. Surely, we can get one released soon......
Actually,I communicated with my engineer who has capability to develope sip phone for Symbian&WM.Due to different development language ,there have more works to do,such as transplate from C to java platform.Also ,there shoud be using SIP stack ,RTP,etc.In other words,it's should be spend high cost to develope one SIP client for Blackberry.
At last,I wish someone have good financial to support us to develope it .
