[asterisk-users] Presence subscription from other pbx systems

[Jan Fricke]

Hi members,

I have a question regarding presence in asterisk.

I have two PBX systems and would like to connect them. After configuring
each other as sip providers calls between users of the pbx systems are
possible.

Now I'm trying to implement presence between the systems. PBX1 sends
dialog-event SUBSCRIBE messages to PBX2. Asterisk just answers 404 not found
although user 410 exists. I think this is for security reasons. Is there an
option to allow presence subscription from configured providers?

 

Sincerely

 

Jan
