said by real_goose:said by DSLR98004:I have multiple three-line Aastra SIP phones (9143i). I actually only use lines 1 and 2 on a normal basis (one home office line and one personal residence line). Those two lines (DIDs) are registered to the Seattle server. I have a third line/DID that is registered to Houston but is normally not used ($0.99/month insurance).
On my Aastra 6730i I have options to specify backup that seems to work automatically. For line 1 I set:
Proxy Server=tampa.voip.ms
Backup Proxy Server=chicago.voip.ms
Registrar Server=tampa.voip.ms
Backup Registrar Server=chicago.voip.ms
The Status screen field Backup Registrar Used? reports YES or NO to let you know which server is in use.
I will be looking for something other than an Obi with similar functions for the main house unless someone can tell me how to do something like this on an Obi.
My understanding is that the backup server will only be operational if you also make the same server change on the VOIP.ms web site. In other words, I don't believe you can fully automate the server switch using only the Aastra side. Can anyone confirm or correct my understanding?
