[cisco-voip] call-manager-fallback wrong phone dn

Mon Oct 15 06:31:12 EDT 2007

hi,

As you can see I am using two Callmanagers (Auto registration is off on 
both of them)

A interesting thing is...

Callmanagers (Site A)
Voice gateway (Site B)

Before I started one admin from site A logged his extensionmob account 
(1700) onto a phone (Phone 1) on site B (changed DP). This phone keeps 
it number on fallback! Then I thought I did something wrong on the other 
phones. So I logged this extensionmob account onto another phone (Phone 
2) on site B. After fallback the old phone (Phone 1) had again the 1700 
and the phone 2 had again its 65xx number.

So it seems as "something" learned once all phone DNs and on fallback 
they are getting up again. It can't be the phones; I did a hard reset on 
them.  After that I did a restart on that voice gateway. So even the 
voice gateway should now have lost every temporally information about 
any phone and phone DN.
