I am wondering if anyone knows if you can network Norstar MICS and a Siemens Hicom 300E. The 300E will be the main switch of course. I want to connect them using a point to point T1. I know that DID's will route to the norstar and work fine on incoming calls. I do not know if the norstar user can use the outgoing PRI's in the 300E. All outgoing calls would need to go through the 300E. It is QSIG.
