Genesys SIP Deployment with Avaya SES

Hi,

I am exploring the ideal whereby the customer’s backoffice remains with Avaya PABX, but the Call Centre is a full Genesys SIP deployment.

Thus, instead of purchasing AES with TSAPI license (and Elite Agent) - we only need an Avaya SES to provide the SIP trunking to the Genesys SIP server. All agents register to Genesys SIP server.

Feasible ? Anyone deployed such a solution / POC-ed ?

thanks in advance !!
