cpn-blk not working 1

[nym313]

Hi.
I can't get the CPN blocking feature working.

My provider said, that he has a lot of customers using a per call calling number blocking, so Im guessing they have CPN features activated.

I tried with programmed buttons, fac, and Per Station CPN blocking, but none of them worked.
Unfortunately they also do not provide a fac based cpn blocking, so that is also out of the question...

My question would be, is there any other way of blocking the outgoing calling number, or am I missing something?

Thanks in advance for any replies!

I've set this up before. Just need to change "per staiton CPN - send calling number" to r on page 2 of the station form.

Thanks, but I tried that already and it doesn't work...

Not sure if this matters, but are your calls leaving on a PRI?

 

[nym313]

Yes
the trunk group type is isdn-pri

 

[phoneguy55]

Are you able to change the number that leaves via 'cha isdn pub' or 'cha public x'?

That was it!
I didnt know, that was required to program the public-unkown-numbering.
After I added a few extensions, the cpn block/unlbock works like a charm!

Many many thanks!!!
