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

[Ryan Ratliff]

With no MTP in the call flow RTP is point to point.  Hitting the ?  
button twice on the phone that can't hear will bring up call  
statistics.  If it isn't receiving packets then either the remote  
phone can't route to the inside phone or the RTP is getting blocked  
somewhere.

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.
