Hello everyone.
I am using TDE200 with IPCMPR card and on the other hand I have an Asterisk 16.7.0 with Issabel v4 interface.
I have made a SIP trunk connection between these to PBXs and everything is working just well, except calls from the Asterisk to Panasonic, which will be hanging up after 30 seconds.
But calls from the Panasonic to Asterisk is working just fine with no problem.
Also all incoming calls from the Panasonic's COs working just fine.
I am not using NAT on any sides.
I have a Kerio Control firewall in the network and I have set a rule to allow all traffics between the PBXs network and also allowing all kind off SIP TRAFFICs.
I would be much appreciated for any help.
