The

also supports transparency of Tel URI in the Request-URI. The Request-URI is the URI representing the intended destination of a SIP request. The
Unable to show "metadata-from": No such page "_space_variables"
has ability to globalize a Request-URI (to the extent possible) before the call enters the IMS core. Request-URI types include:

  • Local number with or without phone-context, in tel or sip URL format.
  • Global number.
  • Vertical Service Code (VSC) with or without ‘user=dialstring’ – A special code dialed prior to (or instead of) a telephone number that engages some type of special telephone service, and is typically preceded with an asterisk, or * (star), key.
  • Username/Alphanumeric.

The

Unable to show "metadata-from": No such page "_space_variables"
can be configured to manipulate an ingress ‘user=dialstring’ parameter in SIP URI in a Request-URI to a ‘user=phone’ parameter if the PSX manipulates the number.

Conversely, SBC can be configured to transparently pass the Request-URI toward the egress call leg if the Request-URI is not manipulated by PSX. For example, if a VSC is dialed, the VSC is sent “as-is” towards the IMS core. Likewise, if the Request-URI has SIP URI of the form username/alphanumeric (e.g. sip:bob@sonusnet.com), the Request-URI is sent “as-is” towards the IMS core.

The CLI syntax to enable/disable this dial string handling feature is described in CLI Reference Guide section.
