GnuGk and Cisco Callmanager (receiving video conference call).

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

With some study from me, google and the help of the community I've
managed to setup GnuGk based on the nat.ini file.

The gatekeeper.ini file showed below have been tested on making calls
(with a Cisco CTS-SX20 and a Sony PCS-G50) and receiving (number@IP)
with the precious help of a community member.

The problem is that now we've a client that doesn't accept IP calls,
only ISDN and I can't make the Sony to dial successful, and when they
try to call by number@IP it never reaches any of our VCs. They aren't
very flexible and the troubleshooting is on our side. If I've
understand it correctly they are using a Cisco Callmanager to do the
calls.

Maybe someone had already faced this issue or can see something wrong
or missing from my configuration. Please advise.

It was important for us to make this VC work (as always is for
anybody) and if I can't make it work with GnuGk, I'll have to try to
publish one of our VCs directly (and I still don't know what ports to
forward on the firewall).

We've asked the counterpart to dial 024456333@224.69.159.45

IPs are scrambled.

Legend:
10.10.0.123 -> GnuGk
10.10.0.222 -> VC
224.69.159.45 -> our public IP
166.212.263.251 - IP trying to reach us
