I need information about this parameter. Does it apply to all simultaneous calls or to simultaneous calls on a single agent?

Hey <@490185991663910922> 

Concurrency applies to all simultaneous active voice calls across your entire organization, not to a single agent.

What does the parameter relate to? (Custom telephony CPS)

This parameter comes from the communication provider

CPS is our sides safety limit that controls how many outbound calls per second your workspace can start when using a custom SIP provider. A value of 1 CPS means only one new call per second, regardless of your carrier’s limits.

Do I understand correctly that this parameter prevents us from sending more than 1 call per second and receiving incoming calls at the same rate? Does the parameter apply to both incoming and outgoing calls?

CPS parameter applies only to outbound calls,
CPS controls how many outbound calls you can initiate per second.

For custom telephony, the default CPS is 1, and the maximum CPS is calculated as your concurrency limit ÷ 20.

CPS limits by provider are:
Twilio: Default 1, Max 5 (changes take up to 10 minutes)
Telnyx: Default 1, Max 16 (instant updates)
Custom Telephony: Default 1, Max = Concurrency ÷ 20
