Re: [GnomeMeeting-list] router adsl problem

[derek indranet co nz]

Hi,
 The quick way of changing ports is to add a call 

  SetRtpIpPorts(49604, 65000);
  
to the source code. Put this call at the start of
GMH323EndPoint::Initialise

The reason I say this is that some adsl's have H323 stacks that 
are similar to netmeeting 
  ( don't do fast start, 
    don't do h245 tunnelling, 
    put rtp data in the port range 49604-6500)

Derek.
