I'm trying to have a DS2000 w/intramail screen incoming calls for FAX tone and if it's not present route the call to a particular extension (or VM if the ext is not answered).

Trunk is set to direct termination to 700 with no overflow. Answer table is set to table 3. Intramail is set to FAX ext 316. Answer table 3 routes all calls to mailbox 4. Routing mailbox 4 is set to detect fax tone, and to use action table 5 with a timeout of 3 seconds. Action table 5 allows #xxx and a T/O to UTRF ext 305.

Very rarely does a FAX get transferred to ext 316. Almost all FAX calls go directly to ext 305. It doesn't matter if there is a greeting recorded in routing mailbox 4 or not. I've played with the T/O up to 10 seconds and that doesn't appear to matter either.

I know there is a restriction on using ext 316 when using an external VM system. Could I be having an issue along these lines when trying to use it in this manner?

Any thoughts and/or help would be appreciated.
