View source for CPS Calls Per Second

[[File:m4cccpslive.png|right|600px]]Calls Per Second or CPS refers to how many telephone calls can be handled in a second. CPS is one measure of the performance of Switching systems.

= MOR CPS =

MOR system supports up to 100 CPS globally per system.

1 Asterisk server can support up to 50 CPS (most of the time it's closer to 20).

CPS can differ based on the [https://www.kolmisoft.com/softswitches/class-5-softswitch system architecture].

CPS can be limited per Device by using '''Limit up to (number) calls, during (number) seconds''' setting in the [[Device_settings#Advanced | Advanced Device settings]].

CPS can be limited per Provider by using '''Limit up to (number) calls, during (number) seconds''' setting in the [[Providers#Advanced | Advanced Provider settings]].

[[Hangupcause_Codes | HGC]] related to CPS:
 243	Provider skipped because of CPS limitation
 244	Device call aborted because of CPS limitation

<br>
'''NOTE:''' It is important to note that high CPS can bring the server down and no internal limitations will help.
For example, constant 150+ CPS traffic to the MOR is dangerous if MOR does not have a Proxy in the system architecture.

= M4 CPS =

M4 system supports up to 1000 CPS globally per system.

CPS can differ based on the [[M4 System Architecture | system architecture]].

CPS can be limited per OP/TP by using '''Limit up to X Calls, during Y seconds''' setting in the [[M2_Termination_Points#Advanced_Settings | Advanced OP/TP settings]].

CPS can be limited per DP/TP pair in the [[M2_Dial_Peers#Assigning_Termination_Points | DP-TP assigning window]].

[[M4_CPS/CC_Live | CPS live monitoring available]] (not available in all installations).
