A Vobiz SIP credential is a username/password pair your PBX uses to authenticate against an outbound trunk. Use credentials when you can’t whitelist a fixed IP — common for cloud‑hosted PBXes, dynamic IPs, or distributed setups.Documentation Index

Use the credential on a trunk
Once created:- Open an Outbound Trunk.
- Edit the trunk and pick this credential from the Credentials List dropdown.
- Save.
Tips
- One credential per environment. Same logic as one trunk per environment — prevents a leaked staging password from being usable in prod.
- Rotate passwords on offboarding. Setting the credential to
Inactiveis faster than rotating, but rotation eliminates the risk that someone re‑enables it. - Username uniqueness. Vobiz rejects duplicate usernames within your account — pick something descriptive like
acme-prod-pbx-01instead ofsip1.
