Call-by-call service selection
Issue 5 October 2002 1631555-233-506
Using Country Protocol 1, you integrate services and features such as
MEGACOM, ACCUNET, and INWATS onto a single ISDN-PRI trunk group
with flexible assignment of trunks to each service or feature. Calls such as an
incoming 800 Service call that requires through-switching as an Outgoing WATS
call can be routed via the same facility. See the ISDN trunk group screen on page
‘‘ISDN trunk group’’ on page 936 for a listing of available services.
NOTE:
When the Avaya Media Server is connected to 5ESS, all of the services
supported under the Avaya and NI-2 country options are available.
