asterisk users - Apr 2007 - Static in Audio PRI, Got reject for frame 39, retransmitting frame 39 now, updating n_r!

Anyone know what would cause this error?
!! Got reject for frame 39, retransmitting frame 39 now, updating n_r!
!! Got reject for frame 39, retransmitting frame 40 now, updating n_r!

I assume this would cause audio issues as well.  

Thanks,
Steve
