We have a ip403V2, now running 2.1(31) SW, with 2x phone 30's. Certain extns are unable to dial out over the PSTN and on internal calls the recieving end shows "Line Error", although the call does go through. Avaya 9335 handsets are being used, however, same results with a test phone.
Any ideas, there is no programming difference on extn's which work and the ones that don't.
Also some extn's which do work do not show in call status.
