Tip&Ring

15-03-03 is set to special.
NEC is sending out a SLI Card, a shot in the dark.
And we are going to upgrade the software to 1.52.

Thanks for the info.

Hey, Dan, if you think it might be the provider, I don't suppose you have any other dial tone from a different provider (maybe a fax, modem, or alarm line?) that you could swap for diagnosis? (swap back after, of course)

Telephoneguy's idea of testing with the IPK using a diffent provider's dialtone (if it's possible) could isolate this to the current provider. Sorry for my lack of knowledge with the IPKs, but what type of service is being provided to the IPK II (DIDs, Individual POTS, etc.)?

When placing test calls via the IPK, is this symptom isolated to a "specific" faxline, or "any" dialed faxline?

Its most probably provider's problem because manual dialing is going well. Means that DTMF receivers braking dial tone. It is look like that your provider missing some digits from faster dialing. You can try butt set Redial and see or you are going to have the same problem. If yes definitly provider.

I made around 30 test calls with my butt set using redial with no problem. Did the same with the system Dterm phone, again no problem.

Only one provider in these area.

My take from the provider side-
Can you ask your provider if they're using 5ESS? If they are, ask them if they can please run a "Verify Office" [VFY:OFC,DN=XXXXXXX, DIALED DIGITS=XXXXXXX] command to get a full detailed end to end report of the call's treatment. They should also be able to run an IPCT (in-progress call trace) for you to see exactly why you're receiving "their" (keyword) recorded announcement. Since it's their announcement, they should be able to explain why you're receiving it. And if they are 5ESS, the above tests should give them the "WHY" to provide back to you. Hopefully, the provider can be very helpful from their side with this symptom. You're right, dans, this is a headbanger.. :bang: Remember: Even though you are receiving the "that is not a working number" announcement, that is still considered a completed call out at the telco (it's just being routed to their announcement system for a specific reason), and no matter what system they are using, they should be able to tell you why the call is not processing to the fax machine.

Mike,
Thanks for the advice. Getting some providers to perform test is like pulling teeth when they feel with cetain it is not their problem.
I will be back on site Tuesday.

When this is resolved I will post the fix

Looking forward to hearing the solution.

It is a good idea to have provider take a look what is going on but I would like to ask another question. have you try another SL port on that card? Maybe port has some noise?
And one more thing. You can not compair D-term and SL because D-Term has his own DTMF but SL has to use CPU's DTMF receivers.

dan,
have your fax connected to ext 118 call the other one 119.
Do the 2 faxes connect with each other normally?
I think that some fax settings are not matching with the pbx settings,
