Question on Cisco Mobile 8.0 for iPhone

Hi There,


I am recently having problem on connecting the iPhone to the CUCM, I wonder if there is anyone having any idea for me.


The APPS is Cisco Mobile 8.0, and the CUCM is 8.0.3-20000. I added the device as device type = Cisco Dual Mode for iPhone, with TCT_XXXX as the device name. I also added a user for assiciate to the iPhone. The iPhone is connected to the office network via VPN, I could broswer on the admin page of the CUCM after I login the VPN from the iPhone. But the problem is when I try to use the cisco mobile 8.0, I am failed to register to CUCM with error message "cannot connect to server". I am having firewall on the office network, but I checked all TCP and UDP trafic is allowed for the voice subnet.


I tested the same iPhone with another CUCM placed in a different network, and its work...

I noticed that there is different between successful login and un-successful on the network status. for un-successful, the status is [CSINetworkReachability isReachableWithoutRequiringConnection] - flags = 3, and for successful, the status is

[CSINetworkReachability isReachableWithoutRequiringConnection] - flags = 2


I wonder what am I doing wrong, and does anyone have any idea on this issue. Below is the log.


state = 1

  viewcontroller = Title:(null)
