When Twilio's voice and calling products are billed to your account, any partial minutes (under 60 seconds) are rounded up to the next full minute. For example, an automated one-way call of 1 minute and 20 seconds would be billed as 2 minutes. Similarly, a two-way call connecting two different Call SIDs for 1 minute and 20 seconds would bill you for two different calls of 2 minutes.
This policy applies to the following products:
- Programmable Voice
- Twilio Client
- SIP Interface
- Elastic SIP Trunking
- Media Streams
Notice: As of February 28th, 2019, calls to China have a different billing scheme. For more information, please see Calling Limitations to China.
