Issue with One-X Mobile preferred for IP Office

[HBPSYS]

Hi I have ONE X Portal Installed as an application server and my voicemail pro server on Windows 2008 r2. Phone System is running 8.1. One-X Portal works fine internally and externally and I have also installed the ONE-X Mobile preferred application on my mobile. I can make calls using this app no problem and the phone system rings me back. All the IM stuff works as well and can also use the conference facilities. The issue is when I make a call or receive a call I have no options for transfer or hold all I get is the standard IPhone active call screen. I have read the documentation and don't believe I have missed nay steps. Its almost like I need to configure all the FNE codes but I believed this was just for ONE X Mobile essential edition. Also on top of this if I try to play the voicemails through the app its just says "error".

Any help is much appreciated

Thanks

Hi All Some help please and confirm if I have done this correctly...
I have two FQDN's one for IP office (ipo.xxx.com) resolving to the Lan1 address and one for the application server (ucserver.xxx.com) resolving to application server IP address. Both those IP's and NAT'ed to the 1 public IP 41.x.x.x

I have added the IP office FQDN (ipo.xxx.com) to the Lan 1 Voip tab domain name field and the UCserver FQDN to the application server
XMPP address field.

My one x on GSm (3g) works fine with call back but my VOIP fails to register.

What am I doing wrong?
Should the 2 FQDN's point to one Ip address internally?
