Prerequisite Features

SipPrefixAndSuffixAnalysis — where required

The SIP Normalization feature normalizes the request-URI and other select address headers in the received INVITE request.

The SipNormalization uses the Normalization Component to normalize:

  • request URI

  • From address

  • To address

  • P-Asserted-Id address (if present)

  • P-Served-User address (if present).

Note

The SipNormalization feature will only do analysis of an address if:

  • the address is a tel URL

  • the address is a SIP URI, where the user part of the URI is a digit string.

Addresses may contain the digits allowed in a global phone number as per RFC 2806.

URI Phone Context Parameter

If a local tel or SIP URI containing a phone-context parameter is normalised to an internationally formatted number the phone-context parameter will be removed from the updated URI as part of normalisation.
