I have a Polycom 7000e that is having issues connecting with more than 2 bri's. We have a Adtran 550 with PRI to BRI switching. I can call out using any combination of BRI's, but as soon as I try to connect faster than 256K using 3 bri's I get downspeeding on the far end and then the call drops.

I have had Adtran verify the config on the Atlas 550 and the fact that I can connect using any 2 of the 4 bri's shows that the switching is working. I am thinking the Polcom is having an issue trying to bond more than 2 bri's. Please help!!!!! any ideas are welcome.

Does your codec have the Nx64 as well as 112, 128, 224, 256, 330, and 384 data rates enabled under the call preferences? Double check what your outgoing and incoming data rates are set for as well...
