GrayMatter Networks helps hotels modernize communications without turning the PBX into another science project — connecting the phone system to the rest of hotel operations, from PMS workflows and guest communications to visibility, legacy line replacement and crisis response.
GrayMatter Networks is helping hotels move from static phone systems to an evolving communications platform. BrainBox IQ lets the PBX do more than survive; it becomes a base for solving real hotel problems, one IQ Bit at a time.
We build and run hotel-focused communications solutions that connect the phone system to the rest of hotel operations.

The hotel PBX that just works — full PMS integration, unlimited extensions, call accounting and NG911 compliance. Home to brainbox IQ and IQ bits.

Round-the-clock expert support comes as standard — not a paid tier, not a ticket queue.
Full PMS integration and multi-site support, so you can standardize the platform across properties even when each site has different infrastructure.
Modern communications without the legacy price tag.
Built on Sangoma’s FreePBX — open-source and standards-based — with no per-extension licensing. Scale across departments, staff changes or multi-property deployments without surprise licensing costs.
On premises, in the cloud, or both. Keep existing phones and lines where appropriate — SIP, T1/E1/J1 or analog trunking, and existing analog handsets through gateways. No forced rip-and-replace.
