September 28, 2025 — PortSIP Announces PortSIP PBX v22.2.21
PortSIP is pleased to announce the release of PortSIP PBX v22.2.21, delivering key stability improvements and bug fixes across our robust and flexible Unified Communications platform. These updates are part of our continued commitment to performance, reliability, and service excellence for our customers and partners.
What’s New in PortSIP PBX v22.2.21
Enhancements
- The SIP Contact header no longer includes a display name by default.
Bug Fixes
- Fixed an issue where, with multiple extensions registered and Push Notifications enabled, active calls could cause the callmanager service to crash(only occurs if the PBX is the v22.2.20).
- Resolved two queue-handling issues when a queue has only one agent who has Push Notifications enabled and whose phone is in the background with the network disabled (e.g., Wi-Fi/Cellular off or Airplane Mode):
- The agent could remain stuck in ONCALL status after the caller timed out in the queue and hung up.
- The caller might not receive the SIP BYE message after the call timed out in the queue and ended
