Genesys SIP server- Number of Concurrent SIP session

[gen_den]

Hello experts,

Does anyone know how many calls a single SIP server instance can handle concurrently?
Is any documentation available with the details?

Thanks

FYI guys, found the details under :

It depends on some things:
1. Number of licenses - URS has a license feature called router_seats. This is the number of concurrent calls URS can route. Older versions of FlexLM only allow checking out 9999 licenses at once, which means that 9999 calls at most can be handled by a given URS on these conditions. Other than that; For T-Server/SIP Server, the number of calls on Technical DNs (Routing Points, Virtual Queue, etc) is currently unlimited, while the number of Seat DNs (Extensions and ACD Queues) is limited to the number of tserver_sdn feature on your license file.

2. Hardware - Genesys is software and depends on the upper layers to work (Operating System, Host, Network, Storage, RAM, etc). You can find some sizing guides on Genesys Documentation website (https://docs.genesys.com/Home) pointing how to perform a sizing based on your hardware specs. The "Genesys Hardware Sizing Guide" states that, in general, a single instance of SIP Server can handle 15,000 simultaneous calls

According to Genesys, in v8.1.1 "one SIP Server HA pair can handle up to 15000 simultaneous calls and the same number of T-Library connections. To determine the ability to handle a particular load, enter user requirements in the Sizing Tool."
