This is a good link

http://www.cisco.com/en/US/tech/tk652/tk90/technologies_configuration_example09186a008019d649.shtml

Rule of thumb:

a. Incoming cor list should be a superset of outgoing cor list for call to succeed.

b. If you configure incoming and not outgoing (or vice versa) the configured cor list has no effect. Call will pass.

c. Call will fail only if incoming is a subset of outgoing list.

Rule a and c are very important.

You have to define COR names first which are identical to partitions in Callmanager.

dial-peer cor custom

name Intl

name LD

name 911

name local

In the above step i created for partitions (COR names).

Now i have to define incoming and outgoing cor lists, which may be similar to CSS in Callmanager world, but they are not applied exactly the same way we do in Callmanager. Cor lists can be applied to ephones in CME, SRST phones globally in call-manager-fallback mode and dial-peers in a router.

dial-peer cor list local

member local

dial-peer cor list ld

member ld

dial-peer cor list intl

member intl

dial-peer cor list 911

member 911

dial-peer cor list phone1

member 911

member local

dial-peer cor list phone2

member 911

member local

member ld

member intl

dial-peer voice 1 pots

destination-pattern 911

no digit-strip

port 0/0/0:23

cor outgoing 911

dial-peer voice 2 pots

destination-pattern 9[2-9].........

forward-digits 10

port 0/0/0:23

cor outgoing local

dial-peer voice 3 pots

destination-pattern 91[2-9].........

forward-digits 11

port 0/0/0:23

cor outgoing ld

dial-peer voice 4 pots

destination-pattern 9011T

prefix 011

port 0/0/0:23

cor outgoing intl

telephony-service

ephone-dn 1

cor incoming phone1

ephone-dn 2

cor incoming phone2

The above example provides 911 and local access to phone1 and all calls (911, local, ld, intl) to phone2. The dial-peers for PSTN access have cor lists applied in the outbound direction. See how the incoming corlist for phone 1 is not a superset of outgoing dial-peer 3,4 (911, local is there, but no ld and intl access).

In case of phone 2 all 4 cor names are included, which makes it a superset of dial-peers 1,2,3,4. This helps in placing any call to the pstn without any restriction from phone 2.

Hi Sankar,

Another great answer! You really hit the nail on the head with this one. 5 points from this end.

Take care,
