I am in the process of moving a g3v6si into a building that has another g3v6si. I would like to have the moved switch to trunk through the existing switch which as adequate ISDN-PRI Trunking. The moved switch will not have any incomming trunking. It is basically a outbound customer service call center. I am told that to have the station information passed through the existing switch such as caller ID, I need to set up a 767E DS1 card in each of the switches as either a DCS or Tie Trunk with QSIG. Which is the preferred method? And how do I Provision the connection in the software? Can anyone help?
