Hmm - I had been doing some linphone (RedHat 7 - don't know what version of 
speex) to linphone (Blackfin - speex trunk) testing in a lab, and I just got 
static, until I forced it to GSM, and then upgraded speex on the host - GSM 
worked, the speex upgrade worked. 

I guess that looking at: http://fedoraproject.org/wiki/History I forgot how 
long ago RH7 came out... (September 2000).
