PCM WAVE Files to G.711

Hey Guys,
I am trying to read a WAVE file and transmit it over an RTP channel in G.711 format(sample size 8 bits, number of samples per sec 8000). However, most of the wave files I tried had (Format PCM, sample size 8 bits and number of samples per sec 11025). I tried reading the wave file using mmioRead and then converting each PCM sample to g711 ulaw and transmitting. However, since other end thinks the sampling rates as 8kHz, the playback is just noise. How do I get around this problem?
