[asterisk-users] Push presence from one asterisk to another

[Loic Didelot]

Hello,
I would like to push presence from one asterisk to another.

Here is my scenario:
Office A has 3 users: extension 100,101,103
Office B has 3 users: extension 200,201,203

Now 200 would like to see on his phone (BLF) when user 100 is on the
phone.

Asterisk of Office A and Asterisk of Office B can talk to each other.
The phone of Office A can not talk to the Asterisk of Office B. 

So the solution where 200 subscribes to a hint extension on Asterisk of
Office A is not possible.


I have several ideas but I would like to see how others would solve
this. Any minor idea is welcome.

Best regards,
Loic Didelot.
