ISDN "Connected number" sent by OXE - how can I manage it?

[mkrustev]

Hi Guys,
I have a strange problem with one client of mine:

I have an ISDN - T2 link towards the operator.
I have a DID translator routing 139 external number to 39 internal.

If I dial 139 I get connected to 39, but I see
the OXE return "connected number"(which is ISDN information element) different 139 (something much longer and incorrect) and I need to have either nothing returned or the exact number I dialled.

Any ideas on how can I manage/modify the "connected number" returned by OXE?

Regards,
Milen

As I understand this ISDN (so to say:)) feature is also called COLP: Presentation of the actual number reached

[vad]

If you not use personal calling number (Authorize personal calling number use=true in NPD) - CONNECTED number will be the same like for outgoing call (installation number+DID number).
Show t3 trace, NPD from TG, DID rules.

I don't know where to look for the COLP (Connected Number) in the t3 trace.
Here is some t3 output:

The number I am getting is: 202892510000E000030, which is strange..

[vad]

Why you use DID 1 for incoming and 0 for outgoing/connected number (NPD 33)?
In message CONNECT you have no connected number.
manage
Called DID identifier : 1
Calling/Connected DID identifier : 1 !!!

[mkrustev]

Even if I manage both calling and called to be the same DID 1, I still get that long and strange number in return..
Have you had such issue?

I have seen this once. I had no solution for it (the translation doesn't work --- made lots of tests with both automatic and normal translation).

[knightr1der]

can you export your TG config and show it to us here?

edit add:
also please show us how you managed which NPD the TG must use and the settings for that 'External Service' (under TG)

I see
the OXE return "connected number"(which is ISDN information element) different 139 (something much longer and incorrect)

in traces you suppliied there is no CONNECTED NUMBER IE sent by OXE.
Where do you see "something much longer and incorrect" number? On mobile phone display? Then it is your operator/GSM provider who supplies this number.
