[Serusers] One way RTP

Hi, I have 2 SIP Proxy running SER 0.8.14 on Linux SuSe. One in UK and the other one in India. We have numbering plan to re-write host and then transefer the call based on number to either India or UK. When we make calls from UK. Everything is perfect - Rings, connects and RTP flows. But when India calls. We don't get any voice. UK Phone rings, connects but no RTP. All the phones use port 6000. We are using PA168 phones. Any body has any clue? Much appreciate your help. Thanks and Regards, Suvendu. ________________________________________________________________________ Yahoo!
