All, I have a configured CISCO router (IP 192.168.11.1) acting as Gateway and a FreeSwitch server (IP 192.168.11.2). I have around 5 to 10 clients registered to the FreeSwitch server. I came across a weird problem today. I received a call from Cisco Router (Say extension 101) and I accepted the call in my client (say extension 200) which uses PJSUA. I accepted the call and RTP to and fro are excellent. Then I call from another line (say extension 102) in the same router to the same client (200), this time the call was left to ring. Good so far. But after the ring, I received a CANCEL packet from the line 102 and my client ack with 200 OK and then it sent out a 487 CALL Terminated packet and received a ACK from 102. Surprisingly the RTP stream between client and 101 got ended. I noticed that the RTP flows from Router to client but client is not sending any RTP at all. Can anyone please help me understand this issue. --Arun This e-mail and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential and privileged information.
