ISDN error - Invalid number format (incomplete number)

I have a new PRI circuit (I'm new to PRI BTW). I've been testing calls through the new circuit with a dial patters of 9.1234567 and it works fine. When I tried to route 7 digit 9.@ calls it failed. 10 digit 9.@ calls worked fine. What am I missing? The circuit is National ISDN with NI2. I've pated three Q931 debugs below.

Any ideas?

Thanks,

Patrick Brown

Re: ISDN error - Invalid number format (incomplete number)

On the failed call, the Plan is ISDN and Type is national but # is 7 digits, whereas other working 7 digit call type/plan is unknown/unknown.

Perhaps your PRI provider is picky with the type/plan on 7 digit calls. You can force the ISDN numbering type and plan to unknown/unknown under the Gateway config page in Call manager.

You can also set it on the router itself, under the PRI interface with isdn map command.

Also I've seen where unknown/unknown with some providers breaks carrier-provided CLID based services like call-blocker/privacy manager because theres something missing in ISDN headers between the different plans/types these services are looking at.

Re: ISDN error - Invalid number format (incomplete number)

Configure the following on the D channel to overide the plan/type -

interface serial 1/0:23

isdn map address . plan unknown type unknown

This will set all numbers (local and long distance) to unknown/unknown and should make it work
