Found getting UMA to work extremely problimatic. Turns out theres a lot of wifi and port issues that need fixing. I've finally got it working and stable and thought I'd post my settings and where I got them.
My router is a DSL-2640R flashed with v1.06 firmware on talk talk the process may vary slightly on other routers.
The first problem is some blackberry's seem to have a problem maintaining a stable wifi connection where the wifi icon on your device keeps going from white to grey.
Changing the following settings seem to help
These settings are under (advanced settings . wifi settings) on my router
RTS Threshold 2304
Fragmentation Theshold 2304
Becon Period (Reduce this value down from the default 100)
i've set mine at 70 and its fine but simply put, lower is more stable but has the side effect of reducing your blackberries battery life)
Also some basic wifi settings apply like trying to avoid "noisy" wifi channels.
My router has an auto channel scan but you might have to manually find the cleanest wifi channel for your area.
Now you've got a stable wifi connection the next problem is forwarding and prioritising ports. If this isnt set up problems vary from UMA not working at all to things like hearing nothing in phone calls.
On my router I had to give my blackberry a fixed IP to forward the ports to. Some routers can forward to MAC adresses which makes this unessisary.
IP Protocol 50 (ESP)
IP Protocol 51 (AH)
In the UK this traffic needs to be permitted to the Orange network (no other carriers support this service yet) 188.8.131.52/20
On my router I fixed my blackberries IP and forwarded UDP 500 & UDP 4500 this is really quite simple. On my router I went to advanced..port forwarding.
All you need is to add rules for the two ports to your blackberry either via MAC or IP adress router dependant.
As for the IP protocalls I went to advanced - Qos and clicked on Lan Qos. From here you can create rules to prioritise the two protocalls.
Hope this info helps. Its pretty rough so ask if you want to know anything else
