[cisco-voip] Conversion from Centrex to VoIP

[Lund, John C.]

We had the same issue, but now when I bat the phones in, I add "FORWARD ALL DESTINATION" and forward their phone to their full 10 digit centrex number and also prefix it with the outside dial code (9 in our case).  When an IP phone calls their new IP phone (that has not been delivered to them yet), it will forward the call out and back into them like it was an external call.  When the installers install the phone they only have to remember to hit the CFwdALL button to unforward.

Subject: [cisco-voip] Conversion from Centrex to VoIP

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
