CME-to-CME with h323 gw + gk

Hi there :)

I'm trying to connect two CME routers, 2811 with 124T release, to eachother with h323 gateway and gatekeeper config.

1 router is acting as gw and gk, and the other is only configured as gw.

I have tried al kinds of tip's i found on this forum, but no luck whatsoever.

Call's made from fxs ports from gw router to fxs port on gw/gk router work fine, but from ephone to ephone it will not :(.

little sketch: ipphone >> router >> lan >>router>> ipphone.

Would anyone be so kind to post the gatekeeper / gateway parts of a working config with ephone's?.. My config is below, Kind regards MJ.

Re: CME-to-CME with h323 gw + gk

e-phone dns no longer register with H323 gatekeeper

Will register if there is a dialplan configured as well as a secondary number under ephone dn.

In this two configuration steps are required

a. Under the ephone-dn, configure a "secondary" number

b. Under telephony-service, configure a dialplan-pattern.

Your running into a bug CSCsb39861

Re: CME-to-CME with h323 gw + gk

Even when the e-phones are not registerd, you can still make this work by using tech-prefixes.

See this doc for more details
