Deployment & Operations
Practical observations from planning, deploying, testing, monitoring, and operating business phone systems.
How to test SIP DNS SRV failover before an outage
Confirm that the PBX discovers, selects and recovers between SIP SRV targets without waiting for a carrier server to fail in production.
What to send a carrier when escalating a call-quality fault
Give the carrier timestamps, direction, call identifiers and measured media evidence so an intermittent voice fault can be traced quickly.
You can move from PRI to SIP without moving the PBX to the cloud
A carrier access migration and a PBX hosting migration are separate projects. Keep the existing PBX while replacing PRI with SIP when the boundaries support it.
Should a desk phone also act as a branch SBC?
Router phones can remove a separate branch appliance, but they also combine a user endpoint and a network dependency. Use this decision test.
