Moving from ISDN2 to ISDN30/SIP Trunking

Unanswered Question


We are currently on a ISDN2 Line, but we want to switch to ISDN30 or SIP Trunking.

What kind of hardware do we need to purchase for our Cisco 3825 Router for ISDN30 or SIP Trunking? I'm thinking of a PRI card for the ISDN30, but I don't know which one and also if I need any hardware for SIP Trunking.

We currenly have 3 VIC2-2BRI-NT/TE cards, but I don't think that will work for ISDN30 because of the 2 B Channels.



I have this problem too.

For PRI: VWIC-1MFT-E1, or VWIC2-1MFT-T1/E. Also may need additional PVDM2 depending by the number of desired channels.

No HW needed for SIP.
