I've got a solution based on:
1) Cucme with IOS: c2800nm-spservicesk9-mz.124-24.T2.bin
2) Ip Telephony: 7945 and 7911
Everything works fine except for one thing...the softkey "Chiama" doesn't work on 7911 phone, I try to composes the number and then press Chiama but nothing happened!!
I also tried to change IOS and phone firrmware but the result was the same.
I've attached my configuration
Help me please!!
The determining factor for using the "Chiama Softkey" with the Handset On Hook is whether or not the phone model has a speakerphone. If Yes then the Chiama Softkey is supported, if No (like the 7911,7912,7905) then the Chiama Softkey with the Handset On Hook is not supported..You will see that if the Handset is Off-Hook the Softkey will work as desired. This is why you don't see this issue with the 7945's
Hope this helps!
