Hi
I am hoping there are some System/Session Manager experts who can recommend the best best way to set up trunks and routes out of our international Avaya platform. Our SIP trunk Provider is BT (GSIP) and we have 30+ locations around the globe routing in/out of our EMEA hub. This is a 50/50 load balanced delivery to our DCs in London and Frankfurt
At each DC we have a SBC-HA pair (2 total) and 2 x SMs (4 total)...(plus all the other Avaya stuff, lets just look at the SIP trunks)
From each site Location/network Region (NR) we need to send BT a PA-ID or Diversion Header with the identity number the originating location for billing and correct in country call routing (Automatic Number Identification - ANI). Any outbound presented CLI/CPN is taken from the FROM header.
Question - What's the easiest way to always present a fixed 'site ID number' (ANI) so that it appears in the PA-ID or Diversion header but at the same time have the ability to apply any CLI (CPN) presentation(or withold) as per the PUB-UNK table (shown in the FROM header)
We have been told by our business partner that we can put the 'site ID number' in the sig group domain name, i.e. london.442031234500.company.com and this can be extracted on the SBC and added to the diversion header via a script.
This is all well and good but each site will need 4 x O/B trunk (sig) groups so that there is SM redundancy... 4 x 30 sites is a lot of trunk groups for outbound calls.
I wanted to know if there was an easier way to do this. For example can the PA-ID header be manipulated based on the location the call has come from, (assume I have set up the SM Locations and IP ranges to match the CM NR map). I am sure this is doable in SM adaptations but not sure how it would look, were can I get a guide on adaptations and the values/syntax that can be applied
i.e. Can the contact header 'Contact: Test-123400 sip<123400@192.168.10.55:5061;transport=tls>' be looked at and based on an IP subnet, then amend the PA-ID header
so if contact = xxxxx@192.168.10.* make the PA-ID header 442031234500@company.com
Any pointers greatly appreciated
