No one has been able, that I know of, to get the IP cards to work thru NAT yet. Junkman's suggestion looks like the best one.
The problem with VOIP thru a NAT is that the IP Header is modified, but not the data stream, which also includes IP info.
Here's the port info anyway:
Connection Request
StrataNet (QSIG)
4029
TCP
Call Control Channel
StrataNet (QSIG)
6400-8191
TCP
Registering IPT
RAS (H.225)
1718, 1719
UDP
IPT
RTP/RTCP
1500-1503
UDP
IPT
RAS/MEGACO
45152 and 45153 (default)
UDP
Call Control Channel
MEGACO+
2944
TCP
Media Channel for TDM
RTP/RTCP
16384-16511
UDP
Medial Channel for NAT
RTP
20480-20991
UDP
Medial Channel for IP QSIG
RTP/RTCP
20992-24575
UDP
The ones for QSIG are not used for IP phones.
