Hi,
we have CME 12.0 with IOS version isr4300-universalk9.16.06.05.SPA.bin
Firmware version: sip78xx.12-5-1SR1-4 , All phones are 7841
we have the following issue:
SIP IP phone line goes to CFA after the call is end ( previously the call was transferred)
I explain the details:
1. IP phone A calls to IP phone B
2. Phone B transfer the call to IP phone C ( blind o consult)
3. The call is established between IP phone A and IP Phone C
4. After the call is finished the line of IP phone A goes to CFA to extension of IP phone B
5. we need to disable CFA in order to receive calls on IP phone A.
We have tried also firmware 78xx.12-0-1-11 and 78xx.11-7-1-17 but the same results.
Any suggestion for avoiding this behavior?
regards
