T1 Voice WIC Preferred ISDN PRI Specs

john.murg · ‎06-08-2009

Does anyone know which of the following parameters are the "default", "preferred" or available options as it relates to a T1-PRI interface on a UC500?

Number of Digits outpulsed: 4, 7, or 10
ISDN Version: NI-1, NI-2 or Custom

Using CCA 2.0, the number of digits for outbound calls depend on the dialplan configuration. Using the embedded NA dial plan, you can do 7 and 10 digits.

Regarding the switch type, you can select "primary-ni"for National ISDN Switch types 1 and 2, but by default no ISDN configuration is there.

Hope this helps,
