Hi All, I am facing a strange problem while using the MicroSIP based on PjSIP. The Scenario is below: I installed the Microsip on the two Computers. These two different PCs are uisng the internet service from the two different ISPs (Internet Service Providers). Then I register both MicroSIP to the SIP Server. The SIP Server is Asterisk Based. Both MicroSIP registers successfully on the SIP Server. Then I call from one MicroSIP to another MicroSIP on another PC. Call is coming successfully but no voice is not coming after call is received. But When both different PCs use the internet connection from same ISP then call is also coming from one MicroSIP to another and also Voice is coming properly. The SIP Server is on Public IP. But this is strange that it is on the Public IP and call is coming from one ISP network to another but no voice is coming. I have also enabled the "ICE" and used some public Stun Servers like "stun01.sipphone.com" while registering the account on MicroSIP. Also I have used the popular "Xlite" Softphone from Counterpath but still the same problem. Please help me to resolve this urgent issue. Thanks in advance. Regards Varun
