Re: Re: calls from vip-000 fail

It highly depends WHEN the calling endpoint sends the H.245 OLC message.
The last chance to send H.245 OLC message is along with the CONNECT message.
Some gateways send H.245 along with the SETUP message (descibed as
"H245 early connect").
Use Ethereal as Stewart recommended and you will see what is going on.

Also, H.245 tunelling has a little in common with the H245 routed section.

IMHO if H.245 tunelling is enabled in both the gateways, then there is
a little of sense (if any) to use the H245routed section in GnuGK.

H245routed instructs gnugk that also the H.245 signalling shall be
passed through the gatekeeper and not between the endpoints directly.

Someone feel free to correct me if I am wrong.
