If you try to register a 480i with multiple PBX (proxy®istrar) one in the global sip parameters, one in a line config, or both in different line configs using the same extension number, it will register both lines with the 1st pbx.
It works if you use different extensions, just good to be aware of.
Aastras response :-
Unfortunately this is a limitation of the phone and there are no plans to address this on the 480i phones running with the 1.4.2 firmware. I can tell you that this is however planned to be fixed in release 2.2.0 (due in the next month) for the 5xi range of Aastra phones.
FYI – further support requests should be raised through your supplier of the phone.
