log

Enables logging for CSCF sessions meeting the readdress criteria for URI translations.

base-criteria criteria
Specifies the base criteria that packets will be compared against. The following criteria is supported:
  • any: Filters all CSCF sessions.
  • destination aor aor: Filters sessions based on the destination AoR. aor must be an existing AoR from 1 to 79 characters in length.

IMPORTANT:

AoR regular expressions are supported. Refer to the SCM Engineering Rules Appendix in the Session Control Manager Administration Guide for more information about regular expressions.

  • plmn-id mcc mcc_code mnc mnc_code: Filters sessions based on the mobile country and network codes. mcc_code must be a three-digit integer from 200 to 999. mnc_code must be either a two or three-digit integer from 00 to 999 or any (any MNC code).
  • source address ip_address: Filters sessions based on source IP address. ip_address must be expressed in dotted decimal notation for IPv4 or colon notation for IPv6.
  • source aor aor: Filters sessions based on the source AoR. aor must be an existing AoR from 1 to 79 characters in length.
filter-criteria1 criteria
Specifies the filter criteria that packets that have passed the base criteria will be compared against. The following criteria is supported:
  • any: Filters all CSCF sessions.
  • destination aor aor: Filters sessions based on the destination AoR. aor must be an existing AoR from 1 to 79 characters in length.

IMPORTANT:

AoR regular expressions are supported. Refer to the SCM Engineering Rules Appendix in the Session Control Manager Administration Guide for more information about regular expressions.

  • plmn-id mcc mcc_code mnc mnc_code: Filters sessions based on the mobile country and network codes. mcc_code must be a three-digit integer from 200 to 999. mnc_code must be either a two or three-digit integer from 00 to 999 or any (any MNC code).

  • source aor aor: Filters sessions based on the source AoR. aor must be an existing AoR from 1 to 79 characters in length.
filter-criteria2 criteria
Specifies the filter criteria that packets that have passed the base criteria and filter criteria1 will be compared against. The following criteria is supported:
  • any: Filters all CSCF sessions.
  • destination aor aor: Filters sessions based on the destination AoR. aor must be an existing AoR from 1 to 79 characters in length.

IMPORTANT:

AoR regular expressions are supported. Refer to the SCM Engineering Rules Appendix in the Session Control Manager Administration Guide for more information about regular expressions.

  • plmn-id mcc mcc_code mnc mnc_code: Filters sessions based on the mobile country and network codes. mcc_code must be a three-digit integer from 200 to 999. mnc_code must be either a two or three-digit integer from 00 to 999 or any (any MNC code).

Usage:

Use this command to readdress URIs based on specified criteria and enters the URI Readdress Configuration Mode. Readdressing can be used for:

  • Mobility: When roaming in a visited domain.
  • Service Aliases: Resolving well-known addresses via SIP-AS.
  • Number Translation: Adding or deleting prefixes such as +1 to/from PSTN numbers.
  • Voice VPNs: Using inter-office extensions to dial remote offices.
Entering this command results in the following prompt:
[context_name]hostname(config-uri-readdress)#

URI readdress commands are defined in the CSCF URI Readdress Configuration Mode Commands chapter of this reference.


Example:
The following command readdresses sessions to a domain named service.com, filters sessions with a base criteria of the source address (1.2.3.4) and a filter criteria of the destination AoR ($.@test.com):
uri-readdress type service
base-criteria source address 1.2.3.4 filter-criteria1 destination
aor $.@test.com
