I've got one central site with a GK and one remote site with one CCME.

The 2 sites are interconnected through an H323 trunk in g729r8 for voice.

When I sent a fax from remote site to central site the fax is received on central site.

But it's impossible to send a fax from the central site to the remote.

Please find attach the 2 configs and the debugs.

Many thanks in advance for your help.

When the fax is sent, the terminating fax display reception but nothing ?
