Users at one single site are complaining of poor call quality, the MOS is in the high ones. Does everything look OK from the gateway side? Wondering if packets are already marked as EF coming in.

*footnote: This was pointing to an IP I can't find anywhere. I'm thinking this used to be a secondary sub that was removed, I doubt this would cause poor audio though.

Are you experiencing poor audio quality within site, from one site to another or from PSTN? Also, just to be sure that you are using all your DSP resources appropriately, I would add following command to voice-card 0 and voice-port
voice-card 0
dspfarm
dsp services dspfarm
voice-port 0/0/0:23
bearer-cap 3100hz

I would advise you to run a wireshark, while you use Jabber and set up a test call. Then verify if your RTP is indeed marked as ef. Alternately use SPAN in combination with wireshark and run a test call between deskphones and establish if the phones are indeed using ef.
Let us know how you go.
also, is it intentional to allocate 70% of your bandwidth to voice and video?
