I discovered something interesting tonight. I had a customers pri go down a while back due to a cable being cut at the street. After six hours the pri came back up but the customer could not dial out. I went to the site and discovered that they had to use ten digit dialing which they didn't need before. However changing the pri centrex option to unknow or co and the calls would go through as normal, with the option set for ITU...ten digits is needed. This option is only on sofware 2.23 or higher. I think the option defaults to C0 and I may have changed it at some point I don't know. I cannot find anyting about this option in the documentation.

Oh, you can program with an IP 24button set but you have to create a flash button and you might need that button for option changes and it will not work for that...so programming from an IP phone is a bit tricky.

Good catch Derrick!

Although they advise against using and IP phone for programming, I've been doing it for years with no issues. I guess their concern is that there could be some degree of database corruption if something were to go wrong with the IP connection during a programming session.

Another PRI thing that I discoverd today.
FP3.5 and up will forward inbound caller id info across the pri when ringing to an off-net forwarded phone or directly to a speed dial number. This may cause the outbound call to fail and you will get a recording from the telco saying that the call cannot go through. The fix is to contact the telco and tell them to set their equipment to accept ALL outbound cid info not just the BTN from the customer. This is crucial if you ext (off net) forward pri calls to cells or answering services or what ever.

Yeah and trying to explain that to telco is like pulling teeth! That is a great feature. I've used the call pairing at some customer sites for some big wigs and IT guys and they love that they can answer the call from the desk or cell and then they can transfer call back through the system.

The one thing that I did find out about call pairing and Caller ID is that the call must ring directly to the ext. that is paired for the original caller ID to go to the cell. If it rings into VM and transferred to the extension or to an operator and then transferred you don't get the originating caller ID.

Right on there. It depends on how it is transferred. If you blindly transfer to a forwarded phone the original caller id still goes with the call unless you wait for off net forwarded to appear on the screen. If an operator does a supervised transfer...grabs a trunk and dials the number or uses a speed dial number then no original caller id goes with the call.
