[cisco-voip] SOLUTION! One Way Audio Issue with Phones Using ASA5520

[Miller, Steve]

Thanks to all who responded.   We needed to upgrade from ASA software
version 8.0.4 to 8.2 in order to use "Pair Interface MT" which was not
previously available.   Our inbound calls were routing directly to our
ASA device while the outbound calls to the ASA remote phone where
defaulting to a different route.....so we downloaded the new software.
Configuring two different Media Termination Points fixed the issue.
More testing to be done, but everything so far is working great!

One way audio is indicative of a routing issue with the ASA MTA.

We have a remote phone which is connected and everything is working,
except that we have a one way audio issue where the ASA remote phone can
hear us, but we can't hear him.  What path does the Call Manager use
route the incoming voice transmission?  Any suggestions would be
helpful.
