Does Plivo have any restrictions on domestic caller IDs or DTMF?

A caller ID (CLI) is assigned when you make a call. The phone number is transmitted to the caller’s phone. In the case of a domestic CLI, it applies to in-country calls.

 

When a country or region is supported for domestic caller IDs, the caller ID is the  ‘From’ number displayed as-is on the receiver’s device. 

 

Plivo guarantees domestic caller IDs in the following countries:

1. United States
2. Canada
3. United Kingdom
4. Australia
5. Italy
6. Peru 

We are working towards supporting domestic caller IDs across more geographical regions. 

 

Dual-tone multi-frequency tones are audio call signals that are usually transmitted over voice frequencies. A very common use case is to have DTMF tones for interactive voice responses (IVRs) and during conferencing. These are tones that are generated when you push a regular phone’s keys. 

 

As of now, Plivo does not provide DTMF support in China.
