Hi
I am having a problem getting ip rtp priority to work on 2 multilinks. This is resulting in very poor voice quality on lines 2 & 3 for voice traffic travelling towards the remote routers . It works fine on the remote routers traveling back to the HO router . Any reason why ip rtp priority is not in effect on multilinks 2 &3?
