I have recently setup access through Cisco mobile 8 though a couple iphoes on our network.I have desktop integration working fine, I am able to dial out just fine, the only problem is when someone calls in. On the 3G models of iPhone the call only gets 1/2 to 1 ring before it disappears. The call continues to ring on the actual desk phone, but the iPhone notes it as a missed call. On the 3GS models the call rings on the iPhone for the full duration, and you are able to answer it without any problems. Unfortunately I do not have a iPhone 4 to test with right now. Does anyone have any ideas? I have went through the logs for my 3G to see if anything stuck out but it hardly makes mention of the call incoming and makes no mention of the call missing.
Someone had mentioned a similar problem to what I am having currently, but since it was tied to a second issue that was answered I wanted to seperate them out.
Thanks for reading and any help,
Just for documentation the deskphone was not associated to the user. After which sip dual mode timer kicks in. That timer tells the CUCM to call the iphone for that many sec before it uses the gsm
