Incoming SIP call not routing to DDI

[MartinB]

HI Guys

I need some direction please. I think I am missing something somewhere.

I have a new customer with SIP trunk setup but I am struggling to get the calls to DDI extensions.

So the Default DDI translation is set up as

First external number :27116893600
First Internal number :3600

SIP GW 1 is created and it is linked to TG 10 on the system.

I can see in the SIP Invite the provider is sending +2711689xxxx and the NPD for incoming is set up as follow:
It does not matter what I change the Calling Numbering plan to, it does not change the outcome.
-----------------------------------------------------------------------------------
Name : GBN
│ Calling Numbering plan ident. + NPI/TON ISDN International
│ Called numbering plan ident. + NPI/TON: ISDN Unknown
│ Authorize personal calling num use + False
│ Install. number source + None used
│ Default number source + None used
│ Called DID identifier : 0
│ Calling/Connected DID identifier : 0
│ Location ID Source + None
│ Location ID : 0
----------------------------------------------------------------------------------

But all calls end up in the Default entity and follow the default routing in there. Currently I am just sending all calls to a Hunting group.

I asked the provider to remove the + in front of the number in the invite but they say they cannot strip it as it will affect other customers on their network and I need to accommodate the +.

Please see my SIP GW setup
