POTS line in a house. I need to add *99 before outdialing from their fax. I have an old Lucent Partner 509 module that's not doing anything.

If I put the 509 module between the fax and the landline, can it be programmed to insert *99 on the outgoing dial string?

Fax --> extension 10 <---> Line 01 <---- Landline

Why *99 to dial a fax from a pots line.
And yes you should be able to do it.

No, the Partner doesn't have anything in the way of ARS, so there's no way to insert digits on outbound. So, just add the *99 in front of every speed dial and leave a post it note on the machine for manual dialing.

So what does the *99 get you?

They changed their POTS provider to Ooma, a VoIP/SIP provider. So voice works great and is cheap, but they need the *99 to get "Fax mode."

Yeah, the post-it method would work, but it's often easier to program machine than to program users...

It's a relative.

Maybe I should find one of those old Mitel re-dialers that used to be on everybody's long distance lines...

I have some viking hotline dialers around let me see what I can find and I'll shoot you a pm with a price or their cheap enough new

When I started out in the Telecom field, I installed Teltronics Netmanager equal access dialers. They were used to inject a 7 digit PIC override code for Intra-lata calls.
