Parameter

Description

forceReRouteViaPsxuery

Enable this flag to allow 

Unable to show "metadata-from": No such page "_space_variables"
to perform a PSX query for new routes instead of using the IP address received in the Refer-To header.

  • disabled (default) – When this flag is disabled, the 

    Unable to show "metadata-from": No such page "_space_variables"
    does one of following:

    • If the IP address in the Refer-To header is zero or matches the 
      Unable to show "metadata-from": No such page "_space_variables"
      signaling IP address, the 
      Unable to show "metadata-from": No such page "_space_variables"
      performs a PSX query for new routes.
    • If IP address in Refer-To header does not match 
      Unable to show "metadata-from": No such page "_space_variables"
      signaling IP address and it is present in 
      Unable to show "metadata-from": No such page "_space_variables"
      Network Selector table, the 
      Unable to show "metadata-from": No such page "_space_variables"
      sends an INVITE message to the IPTG selected from the Network Selector table.
    • If IP address in the Refer-To header does not match 
      Unable to show "metadata-from": No such page "_space_variables"
      signaling IP address and is not present in the 
      Unable to show "metadata-from": No such page "_space_variables"
      Network Selector table, 
      Unable to show "metadata-from": No such page "_space_variables"
      handles the transfer via the Handle IP Addresses Not Present In Network Selector Table NST field (see below).

  • enabled – Enable flag to cause 

    Unable to show "metadata-from": No such page "_space_variables"
    to always perform a PSX query for new routes, regardless of the IP address received in the Refer-To header.

handleIpAddressesNotPresentInNetworkSelectorTableNst

 

Use this parameter to define how to handle a transferred call when the 
Unable to show "metadata-from": No such page "_space_variables"
does not perform a PSX query for new routes and the IP address from the Refer-To header is not present in the Network Selector table. Options are:
  • rejectCall – The 
    Unable to show "metadata-from": No such page "_space_variables"
    always rejects the call transfer.
  • routeViaDefaultZoneIptg – The 
    Unable to show "metadata-from": No such page "_space_variables"
    sends the call transfer INVITE out from the Default Zone's IPTG.
  • routeViaDefaultiptg – This option is not applicable at this time.
  • routeViaTransferringIptg (default) – The 
    Unable to show "metadata-from": No such page "_space_variables"
    sends the call transfer INVITE back out the transferring IPTG (i.e. the IPTG on which the REFER request arrived).
