[App_rpt-users] RTCM Commands

After reading that IRLP is banned from use on an IRLP box I am saddened, but it makes my decision easier. I'll have to live without the RC-210's and go with Allstar. I have been told however that a RC-210 may be linked in with a URI but over-the-air DTMF will be confusing. We were going to use a computer for cell phone control. I would like to know what the command set is. Can someone point me to the controller commands? Such as kerchunk filter (if it has one), DTMF mute, etc. We do have a phone patch. I assume that since Asterisks is a PBX system a phone patch is built in somehow?
