Windstream - Nuvox RTP SIP PORTS

Recommended Posts

According to windstream Engineering they use the following ports on SIP trunks.


RTP Media

udp range 16384 32767

udp range 49152 53247


Signal Protocol

udp 5060

tcp 5060

udp range 1718 1720

tcp range 1718 1720

udp 2427

tcp 2427

udp 2000

tcp 2000


The RTP range of 49152 - 53247 being lower than the default, may have explained callers being incorrectly connected to other callers. Will update if the problem continues. 2-14-2011
