[cisco-voip] Conversion from Centrex to VoIP

[Carlos Ortiz]

No.  That's why you have to make sure it's some temporary partition that
no one has access to. The Calling Search Space access is the key.

 

1)       Create a partition named "temp-phone"

2)       Add your new phones (DNs) as part of this partition.

3)       At this point since nobody has access to the partition via
Calling Search Space the new phones can't be dialed.

4)       However, whatever dial plan you have in place to get to the
Centrex phones will still work.

5)       When you are ready to disconnect the old phones and move to the
VoIP phone - change the partition of the phone DN to the normal
partition that your internal VoIP users have assigned to their phones.

I had this similar response from a few which I thought would be an
option but won't VoIP users get an error when trying to call them?  They
need to be able to use Centrex until I am ready to make their VoIP phone
live.

Add them to a temporary partition that no one has access to via Calling
Search Spaces.  Then when you want to activate them use BAT to add them
to the real partition they belong to.  This will allow you to add them
to Call Mgr ahead of time but not be accessible from the already
converted VoIP phones....

I asked this question before but did not get a response from anyone.  I
am going to reword it...

We are in the process of switching from Centrex to VoIP.  As we move
along and convert each department, we find timing difficult because as
soon as the phones are entered in Call Manager, those already on VoIP
calling the lines on that phone get an error since the phone is not yet
plugged in.

In addition to having convert the lines from Centrex to our DID block (I
can work around that), we find it difficult to come up with a solution
with being able to work ahead of schedule by adding the phones into Call
Manager without having calling issues from VoIP phones.  

Anyone know of a creative way to add these phones to Call Manager but
isolate them from other VoIP phones until we are ready to deploy them to
desks?  

Thanks,

Lisa
