Hi
I hope someone can help about this

Site A has CM6.3
Site B has IPOffice R9

There´s a Lan to Lan between both sites.
8 channels H.323 IP Trunk between both systems and it was working OK for about two weeks with no problem at all.

Suddenly the users on Site A can make calls to Site B, but users on Site B cannot make calls to Site A (UNOBTAINABLE message on phone display)
Call Monitor says BLOCKED.

We checked everything and nothing was changed, so we decided to use a two days old backup....but now the message is WAITING FOR LINE.
We used a second IPOffice system for testing, but no luck. Same message.

Not having another CM available, we decided to bring a Definity R9.5 to Site B (IPOffice Site) and make a new H.323 Trunk between IPOffice and Definity. The IP Trunk works like a charm.

Then we made a new H.323 IP Trunk between Definity (on Site B) and CM6.3 on Site A....and worked as expected too, in fact users on Site A can call users on Site B, and users on Site B can call users on Site A passing through the Definity path.

Not sure how the IP Trunks doesn´t work just for changing from one CLAN IP address to another???

Anyone having a CM6.3-IPO R9 H.323 IP Trunk can share their prints?

Thank You in advance.
