Goodmorning,

Every account on Site1 view correctly his accounts online but not the others on Site2 (all offline) and viceversa.
Is a “Trunk IAX” limit?

Hi

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

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
