Multi-site setup. Main site has an ASA 5506, site b has a 60F, site C has an ASA 5506.
Ever since adding the 60F into the mix we have had problems with internal calling. All sites used to be 5506.
The phone server is at the Main site.
IPSec tunnels are built between all sites.
At Site B regular inbound/outbound calling works and extension calls to the Main site work.
Extension calls at Site B do not work, there is no audio. A user at Site B dials another user at Site B the phone rings but there is no audio either way.
The same problem happens when Site B tries to call a user at Site C, phone rings, no audio.
I tried disabling all SIP inspection on the 60F but that did not help.
Created a basic traffic shaping policy for RTP but that also did not help.
What am I missing?
