More Information
Registering clients on a multi-node PBX can - under certain circumstances - result in unpredictable behavior when using only numbers and not names.
Example:
PBXxy with NodeA and NodeB.
NodeA has prefix 97 NodeB has prefix 98
UserA is already defined on PBX for NodeA -> 97.11 UserB is already defined on PBX for NodeB -> 98.22
I'm lazy, so I configure only the number in the phones, not the names.
Up to this point, all works ok.
UserA and UserB are registered (Phone 1 "UserA 11"; Phone 2 "UserB 22").
Now, I configure another client on a new phone in NodeA, also again only the number, not the name:
Phone 3 --> 97.34
Aware! UserC is not yet configured in the PBX.
What happens?
The third phone registers as NodeA! (Phone 3 "NodeA 97"). From this point on, the whole NodeA works totally unpredictable - and mostly wrong.
So, please use names and numbers or names alone when dealing with different nodes.
It won't be a problem for small configuration scenarios, but it can be a problem with bigger rollouts.
