We are upgrading an old index PBX to Call Manager 6. The index PBX currently has circuits from 3 telco (BT, COLT, C&W) all 3 present these circuits as DASS. In order to move these over to an IOS gateway i understand we need to migrate from DASS. BT tell us that they will convert DASS to ISDN30 for us, will our gateways (2811 with VWIC2-1MFT-T1/E1) will this support ISDN30?

Yes. Note you also need a minimum of a PVDM2-32 to support a full ISDN30 circuit.

You can check what you have in the router with "show diag".

Please rate post if it does!

also bear in mind that with Euro ISDN at least with Colt you will lose the leading digit zero so you may need to re-insert again otherwise the CLI will look odd
