Maximum Calls Per Second (CPS). We set limitations to the CPS and will reject calls with a ‘486 busy here’ response, should this limit be reached. Typically, the CPS limit is set to 2 CPS for SIP accounts with up to 30 channels, and 5 CPS for SIP accounts with more than 30 channels.
If you have a business need for higher call throughputs, please contact customer service to ensure we serve your needs in the best way possible.
