work, you may need to collect logs from SBC or from Application Solution Module (ASM) yourself, or you may be asked by
Unable to show "metadata-from": No such page "_space_variables"
TAC to do it. In most cases, when a CRM case is opened,
Unable to show "metadata-from": No such page "_space_variables"
TAC will request the relevant logs and configuration backup. In most cases,
Unable to show "metadata-from": No such page "_space_variables"
TAC engineers will need the following files as the minimum requirement to start their analysis:

  1. Unable to show "metadata-from": No such page "_space_variables"

  2. WebUI log with following subsystems enabled:
    • Call Routing Service
    • Common Call Control

    • SIP Stack Service
    • ISDN Protocol
  3. Brief description of the scenario in question with the calling and called party numbers
  4. Peer IP addresses
  5. The Lync Server 2010 Log
  6. ASM (SBA) logs from ASM machine
