fallback due to RTCP timer

I have a customer whose phones are going into fallback on a SRST gateway, and then reregistering to the call managers quite often. Sometimes they don't reregister very easily. I changed a command that was in the config. Used to be "no mgcp timer receive-rtcp", and I set it to the default (guessed it-not in IOS command index for 12.2) "mgcp timer receive-rtcp 5". What direct affect does this timer have? There is no reference to it in the IOS command index. I had several phones not registering, when I stumbled on this and did a "sh rtsp client session history",,,,looked good,, looked bad,,,then it was good again. It registered all the phones, then it deregistered all of them, and then they all synched up again!?!?!?!? The console never showed any messages while this happened. I know what RTP is, and I'm very familiar with it. What is this command supposed to do for me?

Re: fallback due to RTCP timer

I think it does make an impact as I understand from this URL where this command is documented
