SIP timers are not exciting until they are wrong. SignalFoundry produces one-page translator sheets that map SBC timer settings to SD-WAN SLA classes. Network engineers get concrete numbers; contact center leaders get plain-language impact statements on customer hold behavior.
We walk through failure injections documented on video with scrubbed packet captures. The library becomes onboarding material for new network hires who did not live through the original deployment.
When carriers push back, we supply comparative traces showing whether delays originate on-net or off-net. That evidence shortens escalation calls dramatically.
We close with a maintenance checklist so timer reviews happen annually rather than only after incidents. Prevention costs less than reputation repair.
