Getting busy when calling Extention to Cellular station thats disabled

[Joemjauser]

Hi,

I built up some new stations and added off-pbx-telephone stations onto two 9650 phones. These work well when I have the EC500 button enabled. However, if I disable the feature on the phone, then call the station number from a different phone, I get a busy.

If I do a list trace on the staion (760) with ec500 diasbled, then dial 760 from 761, I get the trace below. I here a busy on station 761. Meanwhile 760 is ringing. Any ideas what can be wrong?

Im still getting this busy from the calling end when calling from a CM2 to a s8400 CM 5.2 via an IP tie trunk. The phone being called rings. However, if station 761 has ec500 enabled, it works on both sides of the trunk. ( I hear ringback from the calling end and the phone as well as cell phone ring on the receiving end). If I do a trace on the tac (when ec500 is disabled),I get the following:
