RTP Starting Port Number:
RTP starting port that will be used during the transmission of the audio/voice
packages can be determined through this program. RTP port numbers are used if
there is a call coming from WAN to IP telephones. The firewall or router -or similar
network device- must be programmed such that the call requests from this port
must be forwarded to the IP address of the related telephone.
The other RTP port numbers that will be used by MGW channels are assigned by
adding 2 to the starting RTP port number. For example, when the starting port is
defined as 5000, RTP port for the 0
th
channel will be assigned as 5000; RTP port for
the 1
st
channel will be assigned as 5002, RTP port for the 2
nd
channel will be
assigned as 5004, etc.
