Using ENUM to convert E.164 numbers to FindMe IDs
Using ENUM allows incoming E.164 numbers to be looked up in an ENUM server and the call forwarded to
the URI associated with that number.

Including the ISDN gateway prefix in the caller ID
It is easier to return a PSTN / ISDN call that has been received through an ISDN gateway if the Cisco VCS is
configured to include the prefix of the ISDN gateway in the caller ID.
configured to include the prefix of the ISDN gateway in the caller ID.
To configure the Gateway caller ID on the Cisco VCS:
1. Go to the
H.323
page (
VCS configuration > Protocols > H.323
).
2. Set the Gateway Caller ID as appropriate. The options are:
l
Include prefix: the caller ID displayed on the receiving phone is the caller's phone number prefixed by
the ISDN gateway's prefix. This means the recipient can directly return the call by selecting the number
and pressing return call (provided that an appropriate search rule is in place to allow calls with this prefix
to be routed to the ISDN gateway). This is the recommended option.

l
Exclude prefix: the caller ID displayed on the receiving phone is just the caller's phone number. To
return the call, the number must either be redialed or edited prefixing it with the gateway prefix so that
the call can be routed via the gateway to the telephone network.

Note that if the Cisco VCS interworks an E164 H.323 call, it creates a caller ID with a domain set to the IP
address of the VCS that carried out the interworking. Appropriate search rules must be created to handle the
routing of these calls, or a transform implemented that converts number@IPofVCS into
number@LocalSipDomain
