I have a CCM 4.1 site which is connected to a PABX using an E1 PRI . Calls can happen to and from phones on each system, but when you try and transfer a call from a PABX phone to the CCM system the call gets dropped.
1. Is this a blind transfer or a consult transfer?
2. Does the exact same type of transfer work from PABX phone to another PABX phone?
Some PABX's use a Transfer key that acts more like a Conference key, where the far end phone has to be answered before the Transfer key can be pushed again to complete the transfer.Maybe you are running into this type of scenario.
The PABX can do both blind and Consult transfers . When the user transfers from PABX phone to the IP phone , the call rings on the IP phone. When you pick up the IP phone it shows that you are on a call with the PABX phone extension. You cant hear anything on both sides and about 5 to 10 seconds later the call gets dropped and you hear an engaged tone .
May sound like an odd question but does your PABX allow the transfer of ibound calls to an outside line? I know the one we have here does not and prior to finding that out I was getting a pretty similar situation to what you are getting. If you don't know for sure give it a try. When you get a call comming from the PSTN try to transfer it back to another number across the PSTN. If this does not work then you can't get there from here. If you are able to transfer a PSTN call back to the PSTN then turning on some traces would be of value.
Hi Jared ..I am sure that Tony is on the right track with the external transfer angle. What type of PABX are you integrated with? With our Nortel Meridian 61c the feature Tony is referring to is called
"allow Trunk to Trunk connection". Without this enabled you can call across but not transfer as the Nortel sees the CCM as external.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
