(Describe how to change port numbers)
|As default
|}
 
===Ports===
 
The default SIP port seems to be UDP port 2048, and the default RTP port range is very wide (49152 - 65534). For firewalling reasons you might wish to change the SIP port to 5060, and the RTP port range to be narrower. Both are set on the same page - ''Settings'', ''Advanced'', ''SIP/RTP'':
 
''SIP:'', ''Network identity (port)'' set to 5060.
 
''RTP/RTCP:'', ''Dynamic RTP port start:'' set to e.g. 5000, ''Dynamic RTP port stop:'' set to e.g. 5098.
 
==Other (possibly) useful settings==
