[Asterisk-Users] RTP codec error???

Sorry for my terminology assumptions.

UA = User Agent, which is what the ATA-186 and 7960 are.  Anything 
that normally is what the "end user" has on their desk or on their 
computer (in the case of a softphone) is considered a "UA".

So, since you have both an ATA-186 and Cisco 7960, make the changes I 
describe below.  If you don't understand what they are, take a look 
at the configuration guides for each piece of equipment, located on 
the Cisco website, or alternately use Google (which I find to be more 
useful at finding things than Cisco's terrible search interface.)
