Import phone number
Imports a custom phone number into your workspace. This is useful for direct SIP dialing scenarios where your telephony provider does not offer elastic SIP trunking. Set uac_enabled to true when your carrier or PBX requires outbound SIP REGISTER traffic, and optionally set uac_register_expires (60 to 3600 seconds, default 300). For IP-authenticated providers such as zoom, ringcx, five9, and 8x8, termination_uri is filled automatically. For 8x8, omit phone_number to have Synthflow generate the 12-digit identifier required for SIP routing.
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Request
The phone number to import. Required for most providers. For provider_name=8x8, omit this field to auto-generate the required 12-digit identifier (0-9 only). If supplied, it must contain only digits and be at least 12 digits long.
A human-readable name for the phone number.
Phone number provider. Use 8x8 for 8x8 Contact Center (SIP domain sip.8x8.com), zoom for Zoom, ringcx for RingCX, five9 for Five9, or omit/custom for a generic SIP trunk.
Optional SIP trunk username for authentication. Required when uac_enabled is true. Not used for five9, ringcx, or zoom.
Optional SIP trunk password for authentication. Required when uac_enabled is true. Not used for five9, ringcx, or zoom.
SIP domain or termination URI used for outbound calls (maps to sip_term_uri). Not required for zoom, ringcx, five9, or 8x8, which set the SIP domain automatically.
Optional outbound proxy used for outbound calls and SIP REGISTER requests. Omit the port to try DNS SRV first, then fall back to A record routing on port 5060 if no SRV record exists. A port limits routing to the A record. For five9, Synthflow sets the regional TLS proxy automatically when omitted.
Optional auth username used for SIP REGISTER requests when it differs from trunk_username.
When true, Synthflow sends outbound SIP REGISTER traffic to your carrier or PBX so it can authenticate outbound calls. Requires trunk_username and trunk_pwd. Defaults to false.
SIP registration refresh interval in seconds. Only used when uac_enabled is true (or for providers that register implicitly, such as RingCentral). Whole numbers only, between 60 and 3600. Defaults to 300.
