Hi All,
I am facing an issue that when IVR transfer the call back to agent , the call gets dropped after few seconds, in this case i saw that Genesys SIP Server uses re-invite as a transfer method.
On the other hand, when SIP Server uses the refer method i could see that the call gets transferred to agent however [b]caller [/b]gets disconnected and i can see the call on agent extension but the original caller is no more available it was disconnected by the system.
Here is the detail of our environment, the CTI method is CTI through SIP Server.
Genesys SIP Server 8.1/GVP 8.1 - 10.142.56.121
Genesys Framework 8.1/TServer for Avaya CM 8.1 - 10.142.56.112
Avaya SES - 10.1.7.56
Avaya AES - 10.1.7.57
Avaya Communcation Manager IP - 10.1.7.50
Call made from Avaya Ext 4029
The call flow is simple , IVR trunk Group DN is 7400, IVR transfer the call to SIP Server RP '7402'.
AT 7402 RP i have put in simple TRoute to transfer the call to Avaya Switch, ISCC is configured between SIP Switch & Avaya Switch so the SIP Server gets the ERP and transfer it using that ERP (7122) to the Avaya RP '7100' which transfer the call finally to any available agent.
I am controlling the Transfer method using oosp-transfer-enabled, when i put it to true it SIP Server transfer the call using refer when i put it false it transfer the call using re-invite.
Avaya SES inbound Trunk has following Annex option, this is the trunk used during the transfer from SIP to Avaya switch.
TServer
userdata-map-filter *
refer-enabled false
contact 10.1.7.56
sip-server-inter-trunk false
oosp-transfer-enabled false
I am posting the SIP Server and SES logs here for both the cases.
Regards
Ali
