Numbering Plan ISDN Luxembourg

Question

Dear,
We have a challenge using a variable length numbering plan in Luxembourg, they use a range of 6 digits +2 digits you choose yourself freely.
So for example if you have a range [phone]XX, the first digits are fixed and behind those you can freely choose.
The provider cuts the first part (6 digits) and you only get the last 2 on your E1 for incomming calls.
This is ok, we have configured this to work with Translation Patterns, but we have one challenge with outgoing calls
With the outgoing calls we only get the first digits to the receiver, so only [phone] but not the last 2 digits, and if the party attempts to do a redial the voicegateway gets an error.
Cause i = 0x809C - Invalid number format (incomplete number)
Does anyone have any experience with these variable number plans, maybe in luxembourg.

Answer 1

If i am guessing this problem correctly then this what happening...
When you receive an inbound call from Telco you only get called number as XX and calling number as [phone]. Now when you make an outbound call (redial) you only able to dialing [phone] without the last two digits and the gateway gives an invalid number format error.
To resolve this first you need to ask Telco to send correct calling number i.e. including last two digits , so that you can redial in correct format.
If my guessing it wrong , can you please explain it with example numbers and call flow.
