Connect MicroSIP to your CallGlobal line
Short answer: In MicroSIP, create an account and set the SIP server, SIP user and password from the number dashboard. On Windows, allow the application to use the microphone and the network required for calls.
MicroSIP handles the phone interface or routing environment; CallGlobal supplies the active line and its account credentials. Keep those responsibilities separate when setting up and troubleshooting.
Prepare MicroSIP for the line
In MicroSIP, create an account and set the SIP server, SIP user and password from the number dashboard. On Windows, allow the application to use the microphone and the network required for calls.
Values and checks before use
- Open the active number in your CallGlobal dashboard and obtain its current SIP server, username and password.
- Place each value in the corresponding account field; do not reuse the website login as the SIP password.
- Use a supported transport and audio configuration, then check whether the client reports a registered account.
- Inspect microphone access and audio routing separately if registration works but calls have no sound.

Keep the connection secure
Restrict access to the SIP password and to any PBX administration panel. Redact credentials before sharing logs, and keep the number renewed so the account remains usable.
CallGlobal does not supply campaign automation, a hosted PBX or predictive dialing. Configure application-specific behavior in the software you operate and follow the rules governing each call.
Frequently asked questions
Which credentials does MicroSIP need?
Use the SIP values attached to the active number. These are separate from the email and password used to sign in to the CallGlobal website.
What if the account registers but audio fails?
Check microphone permissions, the selected audio device, codec compatibility and firewall or NAT handling. Registration and audio use different parts of the connection.
Can the browser be used instead?
Yes. The dashboard includes a web dialer, so a separate SIP client is optional for ordinary browser calling.
