I've created a U-law file for my employer's on-hold message system and it sounds perfect on my end.  When uploaded to the system and played from my employer's computer its has a terrible background static.  All the parameters are set to where the system wants them (employer confirmed with support), 8000Hz, 8 bit, mono, ulaw. 

We were trying to load a tradition file with no luck, as soon as we converted to the proper settings...boom...it uploaded great but had this static.  Perfect on my end.....but end product....no bueno!

 

Any ideas or thoughts would be greatly appreciated.

This is normal for 8-bit audio - it can't have a SNR of more than 6.02 * 8 = about 48dB, which is why you can hear all that noise. That's determined by the Laws of Physics - nothing to do with Adobe. There are some clues as to what you might want to try in this thread.
