Hello all! Been a while since I've visited the forum, and I know this group has the expertise to help with what I think is a simple setup. First, some background.

We inherited a DK280 system when we moved in the building, but for some reason the previous owners took the voicemail PC. We have boards for 16 digital stations, and one board for four analog ports. We only have 10 stations (DKT3020s) in service at the moment, and don't foresee adding any others.

We've been relying on voicemail provided by our carrier (AT&T), but we need more flexibility in having greetings that vary based on day of week (our office hours vary depending on the day), and also provide rudimentary IVR for getting directions, list of services, etc. I've set up an Asterisk box that seems more than capable of handling voicemail and the basic IVR. I have all the voice prompts programmed and the voicemail set up.

I ran a line from on of the RSTU ports to one of the analog ports on my Asterisk box (using an OpenVox A800P04 with 4 FXO), and I can dial the voicemail extension (216) and I hear my prompts. However, I can't get DTMF keypresses on a DKT3020 station to go-- I get silence instead. Also, when I hang up, the DK280 doesn't drop the RSTU port. But all this is just testing...

Some questions:

1) I have an RSSU1A card so I can build a PPTC9 cable (based on the Strata manual I have) to the Asterisk box for SMDI if necessary, but do I have to? I intend to have our receptionists use the Asterisk web-based message center to handle voicemails. Is SMDI required? How do I set it up?

2) Since the digital stations aren't sending DTMF to my analog voicemail port, how do I change that configuration? I've searched this monster manual and simply cant find it. Cant find it in the manual for the station, either.

3) What other programs on the DK280 do I need to check/change to make sure voicemail is working? What are the reccomended settings for this setup?

Eventually, we're going to transition to an all-Asterisk setup, with SIP phones to replace the stations we have now, but there's a budget limitation that is going to delay that for a while.

Any ideas, suggestions, programming steps, or pointers to resources would be greatly appreciated!

Does the system have a DTMF receiver(RRCS) on the processor? I would think it does if it had a voicemail on it before . Make sure the code in program 03 is set to 92 if there is a 4 circuit DTMF and 93 if there is a 8 circuit DTMF receiver

I can't pull the card at the moment, but there does appear to be an RRCS mounted on the RCTUA3 board.

Program 03 was set for code 91 on slot 00. Changed to 92 (appears to be a 4-channel RRCS -- has two rows of chips soldered in). Ran 91-2 to init to working memory. Still no DTMF after dialing VM port 16.

kewl thanks! That got DTMF working (Program 31).

Next question: How does the DK280 know, or rather, how do I configure it to forward to vm on no answer, etc. We'll simply have one voicemail box for the business. No voicemail for individuals at this time--maybe after we go all-Asterisk.

I guess I should add a little about our station configuration. I have ports 000-003 (receptionists) set for immediat ring in program 81, ports 004-039 (offices) to ring after 24 seconds with program 83. (Forgot there's another PDKU after the RSTU card. Cards in the chassis are: *empty*, RCTUA3+RRCS, PDKU2, PDKU2, RCOU+RCOS, RSTU2, PDKU2, RSSU1A).
