What we support

SecondRing Softphone — your business line on your mobile

The SecondRing Softphone turns your mobile into an extension of your business phone system. Work from home, the office or on the move while using your SecondRing number. Calls made through the app can present your SecondRing number, so you do not need to give customers your personal mobile number.

Register the app to your SecondRing extension to use available phone system features such as call groups, voicemail, call recording and call barring. The softphone is free to download for iPhone, Android, desktop and Mac. Calls are charged at standard rates, and mobile data charges may apply when you are away from Wi-Fi.

Bring your own compatible device

Prefer a desk phone or your own equipment? Subject to compatibility and account approval, we can provide SIP configuration details for a supported device. Options may include SIP phones, analogue telephone adapters (ATAs), gateways and PBX systems.

Cisco ATA 191
Grandstream HT801 and HT802
Fanvil IP phones and ATAs
Yealink and Snom SIP phones
Poly VVX and Gigaset IP phones
AudioCodes ATAs and Patton gateways
3CX, FreePBX and Asterisk systems
Other compatible standards-based SIP devices

We can also assess devices from manufacturers including D-Link, Linksys and Nokia. Compatibility depends on the model, firmware, network, NAT settings and the features you need. Please check with us before purchasing equipment.

Using your own equipment? Back up its settings before any factory reset, and change the default administrator password to a strong, unique password. Keep your SIP credentials private and secure.

Customer-owned devices must be configured and secured correctly. SecondRing cannot accept responsibility for misuse, unexpected charges or service issues caused by a compromised or incorrectly configured customer-owned device.

If you would prefer us to provide the hardware, ask about a compatible device as part of your SecondRing setup.
