How exactly does the failover (secondary pbx) work on the Sangoma P phones?
Questions
#1
I see how to add the 2nd pbx IP address in the FreePBX Gui in the phone settngs. However, there is no place for auth user/pass for that failover. Does it have to be the exact same auth user/pass on both pbx systems?
#2
Is the phone actively registered to both pbx at the same time so that it can receive a call from either pbx at any time? Or does it ONLY register to the 2nd pbx when the primary pbx is down?
#1 The idea is that the extensions completely match on both PBXs. #2 It only registers to the primary and fails over to the secondary if it looses the connection to the primary.
I wish they could actually register to 2 pbx (at the same time). I have 2 freepbx servers, but if the sip trunk on pbx #1 goes down and the incoming call goes to pbx #2, the phone won’t get the call because the phone is still successfully registered to pbx #1.
Not being able to register to both pbx servers messes up my redundancy strategy.
Most sip phones can register to multiple pbx servers at the same time.
“Sangoma phones, beginning with phone firmware 1.1 and DPMA 1.3, support simultaneous registration to two hosts.”
So, you are saying, 100% that the “simultaneous registration” is still ONLY 1 or the other? The phone absolutely cannot receive a call from host2 if host1 is currently registered?
Oh HEY! That is new information to me and I didn’t realize that the latest firmware versions have this functionality enabled. I can actually confirm that I am seeing P325 phones with the latest firmware actually registered to our fail over PBX.
Haven’t really tested it as this is a pretty new feature and don’t really have an easy way to test it as the implementation is pretty large and offsite but I don’t see why not given that the phone is registered in both spots.
