I recently installed seperate PRI's on a BCM 400 Rls 4.0 and on a MICS Rls 7.0. Everything works fine on both except I can't get the operator position to get a 2nd incoming call on the same target line while she is on an existing call from the same target line. The second call does not ring or flash on her phone. I have her phone set up for 5 intercom buttons and the target line is set to "ring only". Shouldn't she be able to get multiple calls on the same target line? My tech support people say yes but can't tell me what's wrong. Help!!
