I'm looking to have a go with the ASA phone proxy.
I've found lots of stuff on the web about configuring the ASA side of things. The thing I can't find, is how you tell the phone the external TFTP IP address.
One person says it's something you have to statically configure into the phone. I don't like the idea of that - doesn't make it very user friendly. Especially when you then have to de-configure this if you bring the phone back into the office.
Another person one time told me that you can put the information "somewhere" into CUCM (I'm on 8.0.3) and it will provision the info down to the phone. (Assuming the phone is in the office before going out)
Can anyone help ? Google just keeps on giving me ASA configuration guides :-(
