The issue is that the lifesize (you are using) and marial do not support
H.460.18/.19
You need to see this in the trace of the RRQ
featureSet = {
replacementFeatureSet = false
supportedFeatures = 1 entries {
[0]={
id = standard 18
Neither of them do so neither of them are able to work behind a NAT.
Xmeeting does not support H.460.18/.19 however it is using STUN to open
pinhole in the NAT and register with gatekeeper using the detected external
IP address and port hence the RCF with data=NoNat in the nonStandard field.
The use of STUN only works with some NAT and not all and some of the calls
will fail.
There are a quite a few hardware however very few software devices that I
know of (other than PacPhone) that actually supports H.460.18/.19.

Hi Jan, thanks again for the help!
I realized that H.460.18 is only supported in the latest release (2.3.1) so
that is why I compiled my own version of 2.3.1. This version however has the
issues described in my previous email: Registration of endpoints end up in a
loop.

Hi Siet,
support for H.460.18 was added in 2.3.0 and significatly improved in 2.3.1,
it won't work in 2.2.7.
Sorry,
Jan
