We have had several customers do this to interface VHF radio repeaters. It works using G729 codecs - you need to set up the QOS on the frame relay side of things to ensure the audio quality is maintained when the link is congested.1 call will take up 24K without CRTP. The compression will add a litlle distortion to the signal, so the radios may need to be tolerant of this. If the G729 doesn't work, you can try some of the higher bit rate codecs, such as 16K or 32K.
To conserve BW and have good quality the 729 codec is the best. If you are concerned about BW then the 711 codec would be the way to go. I am attaching a URL that goes over the testing and the scores received with each codec(MOS).
