OnSIP vs Zoho Voice

OnSIP is a business phone system with multiple business numbers, an auto attendant, custom call routing, and voicemail transcription. It provides desktop and mobile apps as well as a browser softphone, available in Chrome, Firefox, and Opera. Apps are listed for Windows, Mac, iPhone, and Android. The free plan supports up to 100 users and unlimited extensions, and includes Zendesk, HubSpot, and Odoo integrations. Free SIP accounts cannot dial regular phone numbers; paid plans offer a SIP-to-PSTN gateway. Paid plans start at $18.95/user/mo, and a 30-day trial is listed. Month-to-month contracts are available, with payment based on users and features. A SIP address can have active registrations on up to 10 devices. Softphone apps provide end-to-end encryption, and encryption is also available for desk phones. When both parties use the OnSIP app, professional call-link media is encrypted using DTLS SRTP. The Admin Portal supports setup, real-time feature edits, payment and contact management, and invoices.
