Overview

Providers are global carrier trunks or external services used by routing profiles, inbound DIDs, SMS delivery, and cost handling. Use Admin > Providers to create SIP, PJSIP, IAX2, DAHDI, LOCAL, or SMS providers and to review live channel counters.

Technology Selection

Configuration Workflow

• Create or open a provider from Admin > Providers.
• Complete the shared identity, outbound, and inbound fields that apply to the selected technology.
• For SIP, PJSIP, or IAX2, enable Use Realtime Account when MiRTA PBX should maintain the Asterisk realtime rows.
• Save the provider only after replacing the fictional documentation values with carrier-supplied production values.
• Assign providers to routing profiles and test inbound DID matching, outbound dialing, caller ID presentation, and SMS delivery.

Operational Notes

• Provider changes are global and can affect multiple tenants, routing profiles, DIDs, and SMS routes.
• Use documentation-reserved IP addresses and example domains only for training material; never use them in production trunks.
• Provider-level CallerID and CallerID Name override extension-derived caller ID for every call through the provider.
• Max outbound channels prevents a trunk from being overused. When the limit is reached, routing can continue to another provider.
