WHATSAPP CALLS
Customers’ WhatsApp calls — to your phone system (PBX) and 3CX
The customer calls your business number on WhatsApp, and the call arrives in the same phone system where you already take regular calls. 3CX Cloud LT routes it to 3CX or another PBX — no need to change your system.

How does a WhatsApp call reach the phone system?
The customer calls your business number on WhatsApp. The call is routed to your phone system (PBX) and 3CX, and the agent answers it just like a regular phone call. All communication stays in the same system.

Which phone systems do WhatsApp calls work with?
Not only 3CX. 3CX Cloud LT routes WhatsApp calls to your phone system (PBX) and 3CX: to 3CX directly, and to another PBX via its SIP trunk. There is no need to change the system your team works in.

Your system stays
No need to migrate extensions or settings.
Plus regular calls

Do the same features apply to WhatsApp calls?
Yes. In the system a WhatsApp call is a call like any other, so the same features your phone system has apply to it: queues, transfer, call recording and statistics.
Queues
WhatsApp calls go into the same queues as regular ones.
Transfer
The call can be passed to a colleague or another department.
Call recording
Recorded the same way as other calls.
Statistics
WhatsApp calls appear in the shared reports.
Why accept WhatsApp calls?
Many people use WhatsApp every day, so for them it is the easiest way to get in touch. When all calls reach one system, agents do not have to jump between apps and fewer calls are lost.
Convenient for customers
The customer chooses a channel they already use every day.
Calls from abroad
A WhatsApp call travels over the internet, with no extra cost to the customer.
Fewer lost contacts
The call does not get stuck in a separate app on a phone.
One standard
All calls are handled by the same rules.
