Tune Up Genesys T-Server CTI Link With Avaya

Product: Genesys T-Server
Other product: Avaya PBX

In Genesys T-Server, following parameter option allows T-Server to send more messages per second to Avaya PBX for high volume call center

use-link-bandwidth

This parameter has max value of 999 in version 7.x, but 3,000 in version 8.x.

Avaya CTI link supports 1,000 messages per second. I yet to refer to their manual to determine the max value

Following error message can be observed in T-Server log if it hits the max value. This example show the use-link-bandwidth is set to 300 msg/sec

13:20:11 ERROR:CRITICAL:TSAPI:TSERVER:../ClnMsg.cpp/419 10 CLNTMSG[1]: Message CSTAMonitorCallsViaDevice for client Genesys avayatsapi_server ac 10.52.151.6, driver AVAYA#SWITCH#CSTA#KFNAY6206P, is being rejected because of driver flow control. The number of messages for this driver exceeds the allowed threshold. Messages Queued to Tserver/Driver: 752 (0x2f0), Priority Messages Queued: 0 (0×0), Messages Allocated: 51 (0×33), Max Flow Allowed: 300 (0×12C)

I highly recommend to hire vendor to perform load test to ensure Genesys and Avaya are tuned to support maximum supported calls, regardless it is inbound or outbound. Even a simple test scenario will cover 90% and discover any potential issue which will minimize business impact.

After the test, CCA data can be purged to save database size, as well as outbound related tables. Following are other tables which should be clean up after the test
