What it is and why consider it
Snom M58 provides a desk-phone layout over a DECT radio connection. It can serve a workstation without an Ethernet drop while preserving visible held-call controls through the compatible base system.
Reasons to choose something else
This is a DECT desk phone, not a Wi-Fi or standalone wired SIP endpoint. Validate the M500 system and Shared Call Emulation behavior as a whole; handset features do not establish base capacity.
Deployment and acceptance checks
Pilot the physical call-handling workflow, particularly held-call retrieval and monitored contacts. Confirm the exact firmware and provisioning path, then repeat registration and a transfer after restarting the device. For DECT, include an occupied-site coverage survey.
Record the ordered model, hardware revision, installed firmware and calling platform together. Confirm administrator and provisioning ownership before connecting a previously used device. Keep the previous configuration and a supported recovery method before changing firmware; an arbitrary downgrade can remove security fixes.
Firmware, support and evidence
Use the linked Snom support resources to match the device to its approved firmware and provisioning instructions. The facts above come from manufacturer documentation; no hands-on measurements, current price or merchant offer are implied.
Where the table does not specify display, SIP-account capacity, network ports, PoE, Wi-Fi, Bluetooth, codecs, headset or expansion support, that field remains unverified for this record. A base station, handset and accessory have different responsibilities; do not copy a feature between them. Confirm lifecycle notices and support entitlement before a fleet purchase.
