We have a new block of DID numbers assigned to our existing PRI. I can't figure out how to get them to work for the inbound side. I have created extensions that can call out and work just fine internally. I created the CPN substitution for the outbound caller ID. I can not get inbound numbers to go through. We get an error that the number is no longer in service, etc... Provider tested and said PBX refused the numbers. Is there something else that has to be configured? Thanks!

How many digits are being delivered? If it is 4, then you need to have an extension, or something, with that 4 digit number. Do the other existing DID’s have matching extensions? You may need to check the trunk service assignment. At the maint screen type loc num xxxx, xxxx being your delivered DID number, there may be a conflict.

I did configure the extension. I can make internal 4 digit calls as well as outbound calls from that extension.

I get the proper reply from the "loc num xxxx" command typed in

RESPONSE:
The number refers to a 5212dm.

The current extensions are 4300-4319. The new extensions are 4360-4379.

It sounds like it’s in the provider’s provisioning. Try a few test calls with the new and existing numbers and check the smdr (logs re smdr new 12) to see if anything at all came in on the trunks. They may be trying to send you more or less than 4 digits.

The message " line is not in service at his time" tells you that DID range wasn't released or not ported over your T1. If it would be your system you will have message "All circuits are busy please try it later" or something like that.

Exact message when calling on the outside line is "Lines are temporarily busy, please try your call again later"...

Provider ran a Q.931 and the PBX replied with unassigned number.

I had that "line is not available" when I didn't have a number properly programmed into our 3300. I couldn't believe it worked that way but it did.

Hi I'm getting a similar problem with ome lines we had ported over today - I ran a CCS trace and can see the line coming in when I call it form my mobile but its not ringing on the Key Appearance..?

Be sure that the carrier is only sending 4 digits. Create an extension that matches the first 7 digits of the complete phone number (including area code). Create an ext. that matches the last 7 digits. See if different combinations cause any change to your symptons.

here is the smdr log as listed above to try:

11/05 09:10A 00:00:12 7007 1xxxxxx4364 T123
11/05 09:10A 00:00:00 T101 *** 754364 E

Looks like the PBX is responding to the inbound number, what does the 754364 mean? 4364 is the extension that was called, why is it showing 75 before it? Not sure what it means.

Anyone know what that indicates?

Thanks

It looks like some kind of digit substitution going on on the trunks but you say the others are working correctly. It has to have something to do with the number of digits that are being repeated by the CO - unless you only have certain DID's going to certain channels on the PRI and the new DID's going to another group. I still vote for some kind of problem with the CO

The carrier is sending you more than 4 digits!!
Isn't 754364 the last 6 digits of the phone number???????

No, the last 6 digits are 674364

Do you get the same '75' digits with every DID call in that block?

Make sure you check your trunk service assignment for the correct number of digits to absorb or insert. If you are getting 4 digits make sure you have a 0 for number of digits to absorb. You can't leave it blank.

Also, use ccs trace to see exactly what the carrier is delivering.

Trunk service assignment and Class of service assignment are definitely in the right direction...

According to the SMDR logs all the incoming calls have the 75 pumped in front of them like this:

11/05 03:19P 00:01:33 T101 003 754302 4302 4302

Somehow it translates 754302 into 4302 and the call goes through.

My other did range works fine this way, just this new one not working.

Still learning!

OK, now it all makes sense. When they set this 3300 up they used system speed calls to forward the extensions.

So the provider sends 4 digits, the PBX takes it and adds 75 in front, then there is a system speed call that takes 75xxxx and forwards to xxxx.

Wow, that was brutal....

Thank you all for your assistance, the thing that did it for me was checking the trunk service assignment to see that the 75 was being pumped in.

The only reason they did that was, that there must be some conflicting DID's coming in that needed to be modified.

I assume that they are coming in on different trunks, otherwise adding the digits won't do anything except make it a longer conflict. It would probably make more sense in the long run to have the carrier send more digits. You can still use system speedcall to send it to your 4 digit extentsion, but it'll eliminate the conflict.
