[Freeswitch-users] FS doesn't update rtp port when sip UPDATE message changed the rtp port

[Lei Tang]

Hi all, I'm using  FS 1.5,  doesn't somebody known something about this
problem?
My scenario is :
A(FreeSwitch)                      B
      ------INVITE ------->
      <----100 Tring--------
      <----180 Ring --------   with sdp m=audio 55066 RTP/AVP 0 120  c=IN
IP4 10.36.143.76
      <----UPDATE -------    with sdp m=audio 45486 RTP/AVP 0 120  c=IN IP4
10.36.143.76
      -----200 OK  ------>     response for UPDATE message
      <---- 200 OK--------     response for INVITE message,  with sdp
m=audio 45486 RTP/AVP 0 120  c=IN IP4 10.36.143.76
      --------ACK --------->
The problem is, B changed the rtp port in UPDATE message and "200 OK"
response message, but FS didn't do update , so it still send and receive
data from port 55066.
Is this a bug in FS? Does someone known something about this problem?   Any
advice is appreciated!
