Trunk IAX + view contacts presence problem

I have 2 PBX Asterisk in trunk IAX and everything is ok but not the visibility of the presence’s state of softphone account… :question:
Every account on Site1 view correctly his accounts online but not the others on Site2 (all offline) and viceversa.
Is a “Trunk IAX” limit?
Can anyone help me?
Thanks for any informations


Firstly how are you seeing the presence of the extensions ? what softphone are you using ?

for inter system prensence look at for exaple.


Hi Ian,
I use 2 Elastix and all softphone Counterpath Eyebeam/Bria.
In contact list I can call every account but I see online only the contacts of my site.
Idem for other site.

Many thanks
