The Unable to show "metadata-from": No such page "_space_variables" supports the Test Call Number Profile for maintenance blocking between interconnected operator's networks. When the calling party's category is applied to indicate that the call is "test call," a cpc parameter with the value test is inserted in the P-Asserted-Identity header field of the initial INVITE request. When the Unable to show "metadata-from": No such page "_space_variables" observes cpc=test in the PAI header field, the call is treated as a test call.
To use the Test Call Number Profile in conjuction with the IP trunk group blocking functionality, refer to <TBD>.
Info
The blocking function restricts the SBC from sending a SIP request (outside an existing dialog) from its own network to the opposite network, but does not restrict receiving a SIP request (outside an existing dialog) from the opposite network to its own network.
