Hello there, I have been using asterisk as VoIP for few month as gateway for both softphone & hardphone. It's working great. I just bought two T100P cards to setup for the PBX system as gateway that would accept incoming calls and use VoIP for outbound calls. Here is my plan looks like: Current working PBX: PTSN T1 --> T1(CSU) --> Mitel SX200 PBX --> Phones New plan with Asterisk: PTSN T1 --> T1(CSU) --> T100P (first card) T100P (second card) --> Mitel SX200 PBX --> Phones The current PBX is currently running. It uses straight through cable from the T1 CSU (box) to Mitel PBX. When I unplug the cable to put in the T100P card, the light is still RED. I have test with both straight through & crossover T1 cable. No luck. Can anyone help me how to make this work? Thanks.
