I have a odd issue going on, I have a UC520 running CME 7.0 (IOS 12.4(20)T2) SIP trunked to a CUCM 7.1 cluster. To my knowledge all calls between the two work well in both directions, with one exception. The UC520 terminates some FXO lines from the PSTN. Inbound calls on those FXO ports, when transferred to phones on the CUCM cluster, get only dead air. Oddly, I've discovered that DTMF can be heard, just no (other) audio in either direction, so I'm leaning to a trancoding issue. I have calls between the two using G729, and I'm not positive that my xcoder config is correct in CME. I'm attaching an abbreviated config. There are a slew of dial peers in the whole config, but I only included the one I've been testing with. I'm sure there is some enviroment info that I've left, so just ask if there's anything else you need to know. Any help you can give to figure out why these calls aren't working properly will be great appreciated!

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
