CUCM 6.1.2 - RightFax SR140 - 2811 H.323 gateway: outbound problem disconnect after 15s

[sympany-les]

We a working FoIP Implementation:

RightFax SR140, Intercluster-Trunk to CUCM 6.1.2, 2811 H.323 voice gateway with IOS 12.4(24)T3 to PSTN.

The problem is, outbound FAX to a FAX-Machine, that answers the call only after more than 15s will be disonnected, before the FAX gets answered.

We already checked all relevant timers on the gateway and the CallManager.

Anyone has an idea, why the gateway disconnects after 15s (voice service voip, h245 tcs timeout is already set to 45s, but the gateway still disconnects after 15s)?

We also tried IOS 12.4(24)T5 (actually the latest release running on this hardware), but the behaviour is the same.

Hi Stefan,

Have you solved it?

I'm having problems with H323 and brooktrout SR140.

Sometimes with somefaxes I get Busy tone detected error and actually Remote Fax-Machine is not busy...

Thanks in advance

Hi Manuel

Unfortunately the problem couldn't be solved so far.

We still have an open TAC-Case.

kind regards
