UK Numbering Plan Problem

Hello can someone assist. I am trying to use the UK numbering plan. This will be the first site that I am using it, at other sites I have entered the route patterns manually.

I have a pattern setup with 9.@ When I make a call I see it arriving at the gateway. I can see the number being dialed on the ISDN but the call never connects, the called phone never rings. I have done a debug q931 output and the only difference i notice between the UKNP and manual RPs is that the called party number is set to Plan:ISDN and Type:National on the call using the UKNP whereas on the call using the manula RP both these entries in the q931 trace are set to Unknown.

Does anyone know what is going on?

Thanks

Steve

Hi, can you post your config.

Re: UK Numbering Plan Problem

Plan:ISDN and Type:National won't work in the UK. They must be unknown. You could override it with a voice translation pattern if you are using h323 gateway, but the point is that the GBNP should NOT be setting these fields.

Just downloaded any looked at the latest one and it IS setting the patterns wrongly! Each pattern in the dialplan definition file has either T:N or T:I set against it. Wrong, Wrong, Wrong! Its a bug - open a tac case and get them to fix it!! They need to take these out so that the calls go out as unknown.

Hi,

Just upgraded out dial plan to 1-1-5 and had this problem on our BT only ISDN 30.

C&W worked fine.

D'oh

Cheers,

Excellent, we're not alone with this one then!! We recently upgraded this for one of our customers and ran into the same issue. Has anyone raised with TAC?

Apparently the addition of the flags was a "fix"

See bug toolkit - CSCsj03506

Re: UK Numbering Plan Problem

Excellent, so the UK Numbering Plan has an apparently intentional setting which means it doesn't work in the UK.

The Bug report says:

For Windows based CCM, Manually Edit the UKNP and add the required flag

T: I (for International)

T: N (for National)

Has anyone any idea how to do this?

Many Thanks

Re: UK Numbering Plan Problem

You can update the plan manually, however it only takes effect every time you cycle the CallManager service. The file is located in c:\Program files\Cisco\DialPlan\.

What you also need to be aware of is that that DNA also needs restarting for DNA to reflect the change.

Hope this helps.

Re: UK Numbering Plan Problem

Anyone know how to edit the UK plan on CM 6.x ?

Re: UK Numbering Plan Problem

I didn't have to edit my dial-plan in the end, I went into the H.323 gateway settings and set the following in the Outbound Calls section:

Called party IE number type unknown: Unknown

Called Numbering Plan: Unknown

Hope this helps

Re: UK Numbering Plan Problem

Just tried UK dialplan again this afternoon and that indeed made it work.

Thanks very much. Now for some filters :)
