Mitel 3300 ICP, E1 PRI ISDN issue

[pasesanchez]

Hi,

A have configured a E1 PRI ISDN to connect to the PSTN, I can make outgoing calls, but the incoming calls are not working. I performed the following command to get traces edt trace tsp l2l3 3 1 2 1 and the traces shows the following error, -0101100 Cause code: requested cct/chan unavail.

Below you have the complete trace output. Our PSTN provider sends the last 3 digits of the DID (000 to 099), In the PBX we have the extensions 4000 to 4099, so I have configured the Trunk Service Assignments to do not absorb any digit and to add the digit 4 to the incoming number.

Appears the span is otherwise up and working, passing outbound traffic OK, correct?

In your trunk service assignment form, make sure you have set number of digits to absorb to zero. If left blank it will not work. Likely your problem isn't this simple, but you'd be surprised at the number of people who overlook this little detail.

 

[pasesanchez]

The number of digits to absorb is set to 0, also the outgoing calls are working.

 

[Mitel100]

Can you turn on the CCs trace and make a call and post the output.

Many thanks

In the report you provided are the digits being received 3514209400?

If yes, then you need to absorb more digits.

Option 1 - Absorb 6 if DN to match 9400

Option 2 - Absorb 3 and create Speedcall 4209400 with actual digits ????

There are other options but They depend on several other factors.

That had me too for a bit kwb, the calling party is 3514209400 sent as part of the CLID.

Try setting up a DN of 0002 and see if that rings.

 

[kwbMitel]

OK 002 are the inbound digits.

Do we have a valid DN of 002?

(There are no stupid questions, only inquisitive idiots)

Back to the simple things, make sure you haven't got non-ddi number set to yes in the class of service for the extns.
