This parameter defines the local RTP-RTCP port pair used to listen and transmit. It

 

 

 

 

is the base RTP port for channel 0. When configured, channel 0 will use this port

 

 

 

 

_value for RTP and the port_value+1 for its RTCP; channel 1 will use port_value+2

 

 

 

 

for RTP and port_value+3 for its RTCP. Local RTP port ranges from 1024 to 65400

 

 

 

 

and must be even. The default value is 5004.
