Avaya IP Office VCM Resources All In Use

Jeremy Boilard

Problem Statement

An Avaya IP Office IPO chassis reports a Major alarm with maintenance object ipoServiceAllResourcesInUse. The alarm description indicates that all Voice Compression Module Channels (VCM) are in use.

Impact

When all VCM channels are consumed, calls that require voice compression resources may fail, experience setup issues, or be unable to establish until channels become available. The condition can indicate high call volume, insufficient VCM capacity, or resources not being released as expected.

Troubleshooting Steps

  1. Confirm the active alarm details on the monitoring platform or Avaya IP Office management interface. Verify the maintenance object is ipoServiceAllResourcesInUse and the affected resource is Voice Compression Module Channels VCM.
  2. Check current call activity and determine whether the number of calls requiring VCM resources is unusually high.
  3. Review recent call routing or configuration changes that may have increased VCM usage, such as codec changes, VoIP trunk changes, remote extension use, or call flows that require transcoding.
  4. Check for related Avaya IP Office warnings or events, such as ipoGenAppOperationalSvcEvent or voicemail-related warnings, that occurred around the same time as the VCM resource alarm.
  5. If call volume is temporarily high, monitor until calls clear and verify whether the alarm clears automatically when VCM channels become available.
  6. If usage remains high with no corresponding call volume, investigate for stuck calls or sessions that may not have released resources correctly.
  7. If operationally approved, clear stuck sessions or restart the affected service/system following standard change-control procedures.
  8. If the alarm recurs during normal traffic, review VCM channel capacity against site call requirements and plan a capacity or configuration adjustment as needed.
  9. Escalate to the voice platform support team or vendor if VCM resources remain fully consumed, the alarm does not clear after usage drops, or additional Avaya IP Office errors are present.

Resolution

No confirmed resolution was provided in the ticket. The alarm should clear when VCM channels are no longer fully consumed. If the condition is caused by normal demand, increase capacity or adjust call routing/codec usage. If caused by stuck resources, clear affected sessions or restart services only with approval and during an appropriate maintenance window.
