Create SIP Line voximplant.sip.add

If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.

Scope: telephony

Who can execute the method: user with the Management of numbers — modification access permission

The method voximplant.sip.add creates a new SIP line associated with an application.

Method Parameters

Required parameters are marked with *

Name `type`	Description
SERVER* `string`	Address of the SIP registration server
LOGIN* `string`	Login for connecting to the server
PASSWORD `string`	Password for connecting to the server. Maximum length — 100 characters. Not required for calling the method, but necessary for working registration with the operator
TYPE `string`	Type of PBX. Possible values: `cloud` - cloud PBX `office` - office PBX Default: `cloud`
TITLE `string`	Name of the connection. If the parameter is not provided, the interface will display a system name based on the connection type: for `cloud` — Cloud PBX (ID) for `office` — Office PBX (ID) where `ID` is the internal identifier of the SIP line record. The `TITLE` field in the method response will be empty in this case

You can connect no more than 10 cloud SIP lines. Exceeding this limit will return the error MAX_CLOUD_PBX
