I have third party CTI Application softphone sending SET_AGENT_STATE_REQ with reason code = 10 to the CTI server.
Call flow is something like this.
CTI Application Softphone --->ICM PG -----CVLAN ----->AES ---------PBX Avaya Communication Manager.
PG Coomunicated with AES via CVLAN application.
Any Reason code within 1-9 will go through successfully, but Event Reason code 10 will not reach AES. The CTI-link configuration is enabled with Two-digit Aux Work Reason code --Y. ( According to Avaya DOC )
This was proved by following call flow ( with Cisco ICM ).
Avaya Jtapi Application --->AES --->PBX Coomunication Manager.
Sniffer traces on PG, will show all the reason codes from 1 -- 9 but for the reason Code 10, Frame itself on sniffer is not identified.
I believe there is a registry setting on PG some thing like ( EnableTwoDigitEventReasonCode set 1 :-) ... but i am not sure. Simillar to EnableSevenDigitExtension under HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\ICM\<cus01>\<PGXX>\PG\CurrentVersion\PIMS\pim1\ATTData\Config\
Any Help much appreciated.
