Long waited but worth it
I was bit worried before buying it. Because I was not sure whether it will work fine or not. I am using it for couple hours by now, it is great with our company sip server and with some public sip servers. Thanks for the product. When gsm call arrives it automatically swicth to gsm call and when it is over it goes back to sip phone. This is great.
