OK, I am lost on this one! Have a 520 and I am trying to over-ride customers default BTN with their DID's. When I go to outbound dialing plan outbound Caller ID. This is what I see. They are not using FXO they are using t1/e1 trunks. I also tried adding the trunk group for t1/e1 but then I get an error saying somthing to the effect "there were errors" but I saw nothing in red.
We have done this out going DID scenario for multiple customers, not sure why this site is giving us a headache. Any thoughts.
The reason you are getting that message, is because the system, or CCA at least, is not detecting a T1/PRI trunk. If the T1E1 trunk is configured and recognized, you should not get this message. I would suggest that you check the T1 trunk settings, and possibly try removing the trunk and re-adding it though CCA again.
