| The Line Side T1 card only supports loop or ground start signalling, so you will have to change the signalling on your conference bridge.
However, if your bridge requires DNIS digits or E&M signalling, you will need to have a regular T1 card. I have had to do this to supply DNIS digits to a PC-based T1 card on an IVR system and it does work OK.
Basically the switch T1 card is set up as a TIE route, and I use CDP to direct the calls to the card, and a Digit Manipulation Table to insert the desired DNIS digits. |
