DigitVoIP Compatible Equipment Guide

1. IP Phones (Desk Phones):

These are dedicated phones that connect directly to your network via Ethernet.

• Poly (formerly Polycom): VVX series (e.g., VVX 250, 350, 450), SoundPoint IP series (older but often still functional).

• Yealink: T-series (e.g., T3x, T4x, T5x series), VP series (video phones).

• Grandstream: GRP series (carrier-grade), GXP series (enterprise), DP series (DECT cordless).

• Cisco: SPA series (e.g., SPA3xx, SPA5xx), 78xx series, 88xx series (often require specific firmware or configuration).

• Fanvil: X series, V series.

• Snom: D series.

• Aastra / Mitel: Various models (check specific model for SIP compatibility).

• Htek: UC series.

2. ATAs (Analog Telephone Adapters):

These devices allow you to connect traditional analog phones or fax machines to the VoIP service.

• Cisco / Linksys: PAP2T (very common, older), SPA112, SPA122, SPA2102.

• Grandstream: HT series (e.g., HT801, HT802, HT81x).

• Poly (formerly Polycom / Obihai): OBi series (e.g., OBi200, OBi202, OBi300, OBi302 - Note: Official support status for newer Obi devices after Poly acquisition can vary).

3. Cordless VoIP Phones (DECT Systems):

These consist of a base station connected to the network and one or more cordless handsets.

• Grandstream: DP series (e.g., DP720 handset, DP750/DP752 base).

• Yealink: W series (e.g., W5xP, W60P, W7xP base/handset systems).

• Panasonic: KX-TGP series (e.g., KX-TGP600).

• Snom: M series.

4. Softphones (Software Clients):

Applications for computers or smartphones that function as phones.

• Zoiper: (Popular multi-platform option)

• Bria / CounterPath: (Professional-grade softphones)

• Linphone: (Open-source option)

• MicroSIP: (Lightweight Windows softphone)

• GS Wave: (Grandstream's mobile app)

• Many others supporting standard SIP accounts.

Key Considerations:

• SIP Protocol: The most crucial factor is that the device supports the standard SIP protocol.

• Unlocked Devices: Ensure the device is not locked to a previous provider.

• Firmware: Sometimes, specific firmware versions might be needed for optimal compatibility or feature support.

• T.38 Fax Support: If you plan to use faxing, ensure your ATA or device explicitly supports the T.38 protocol for reliable faxing over IP.

Essentially, if a device is a standard, unlocked SIP-based VoIP phone, ATA, or softphone, it has a very high probability of working with DigitVoIP.
