Grandstream
Provision and operate Grandstream SIP phones at fleet scale from FreeSDN: templated XML provisioning, bulk reboot and firmware, and status polling.
Beta: hardened May 2026 (11 audit fixes); provisioning and status coverage.
The Grandstream adapter provisions Grandstream SIP desk phones over CGI/HTTP and powers the phone-fleet side of the VoIP and Telephony module. It covers discovery and fleet view, templated XML provisioning (account, codec, BLF keys, DND, time zone, and more), bulk reboot, factory reset, firmware push, and per-phone status polling. It is Beta, hardened in May 2026 with 11 audit fixes.
Grandstream capabilities
Templated fleet provisioning
Define provisioning as XML templates and push them across the fleet, so a hundred desk phones get consistent accounts, codecs, BLF keys, and policies from one place.
Hardened provisioning path
The May 2026 audit encrypted phone credentials at rest, added an SSRF guard on the phone IP, gated factory reset behind the voip.manage_phones permission and firmware push behind site-admin, and required a source-IP allowlist or an HMAC-signed request for provisioning.
- Provisions Grandstream phones over CGI/HTTP.
- Authenticates with a phone username and password stored as an encrypted credential.
