Zoho CRM connects to phone systems through Zoho PhoneBridge, a single integration layer that lets you make and receive calls, see caller details as a screen pop, and log call activity directly against a Lead or Contact record.
Zoho Voice is Zoho's native VoIP solution, requiring no third-party setup. Once integrated, users can make outbound calls directly from Zoho CRM using the click-to-call button next to phone numbers, and incoming calls trigger a screen pop-up showing caller details, whether the user is working in Zoho CRM or the Zoho Voice web or mobile app.
A wide range of third-party providers integrate with Zoho CRM through PhoneBridge, including RingCentral, Twilio, Aircall, Dialpad, Amazon Connect, JustCall, Freshcaller, and CloudTalk, among many others. Some of these have a native integration built directly into Zoho, while others are configured through the Zoho Marketplace. To find a specific provider, search the Zoho Marketplace, or check the PhoneBridge site to confirm current support and setup requirements.
