[SR-Users] URI Mapping in Presence?

[Mark Boyce]

Hi All

Looking for the best way to achieve mapping from requested uri to actual uri in presence subscription.

The scenario I’ve been presented with is that there is a direct relation between extension number and sip user but they are not the same thing.

So for example;

Extension 10 is mapped to SIP user sip-SomethingLong
Extension 11 is mapped to SIP user sip-SomethingEvenLonger

When extension 10 subscribes to 11 we end up with something like this;

From: “Extension 10" <sip:sip-SomethingLong at ourpbx.com:5060>;tag=12345678
To: <sip:11 at ourpbx.com:5060>;tag=987654321-c8bd

I *think* what I need to end up with in presence db is;
presently_uri = sip:sip-SomethingEvenLonger at ourpbx.com
to_user = 10

(Is that right?)

However I can’t see a standard way to achieve this.  Manage_subscribe will let me override the watcher uri but not the watched.


Anyone see a simple way to achieve this?

Thanks
Mark
