Yealink SIP-T33G - Frequently Asked Questions (FAQ)

• Does the SIP-T33G work with my VoIP or PBX platform?
  Yes — the T33G is a standards-based SIP v1/v2 device compatible with most SIP-based IP-PBX and hosted VoIP platforms (e.g., FreePBX, Asterisk, 3CX, BroadWorks). You'll need SIP account credentials from your provider or PBX administrator to register the phone.
• What's the difference between the SIP-T33G and the SIP-T33P?
  Networking is the key difference — the T33G has Dual-port Gigabit Ethernet, while the T33P uses a Two-port 10/100M (Fast Ethernet) switch instead. Both share the same 4 SIP accounts, 2.4" color display, and PoE support.
• Does this phone need a separate power adapter?
  The T33G supports PoE (IEEE 802.3af, Class 1), so it can be powered through a PoE switch or injector over a single Ethernet cable. If your network doesn't provide PoE, a Yealink 5V/0.6A power adapter is required and sold separately.
