Description

Feature name

IPSMGWSCCPAllowlist

Applicable contexts

IPSMGW service

Prerequisite features

None

The IPSMGW SCCP Allowlist Feature rejects OpenRequests from SCCP addresses it does not recognize based on a provisioned allowlist.

Request from non-GT addresses will be allowed without checking the allowlist. If an allowlist is not found, the feature ends immediately, allowing call processing to continue. If the allowlist is then found to be empty, the feature ends, allowing call processing to continue. If the originating address contains GT digits, it will match those against the provisioned allowlist using the list’s configured address search mode. If a match is not found, the incoming leg is released via endSession.
