hi
is it possible in freepbx to register an external extension from another pbx and “represent” it on my pbx?
for example, my pbx is pbx.pbx1.com and all my employees are registered with that and working just fine.
now, i have another extension from pbx2.pbx2.com, completely different pbx.
can i somehow register it in my pbx, and somehow represent it as an extension? (for purposes of blf/free/busy and more)
thank you
