I am having an issue with one way audio that is very limited, but ongoing.
Using a Cisco 3745 with IP-IP Gateway, about 1% of all calls have a one way audio issue after about 1 to 5 minutes (H323-H323).
The one way audio is always to the side to which the calls was made (Ougoing Leg)
We are utilizing the latest IOS (c3745-ipvoice_ivs-mz.124-15.T4.bin, I've also tried with the older IOS's)
I have tried to follow all the one-way audio Suggestions.
voice call send-alert
voice rtp send-recv
h323-gateway voip interface
h323-gateway voip bind srcaddr
no ip route-cache cef
no ip route-cache
no mop enabled
This is on Media Flow-Through with a TCL Script on the Inbound Call Leg.
Here is the only trace info I have that can be possibly be causing this issue:
Mar 6 17:37:18.634: //-/xxxxxxxxxxxx/H323/cch323_h225_receiver: Parse error RXDATA_NONE
Unfortunately Since there is a high volume of calls it is very hard to trace.
Any suggestions for me to tackle this issue would be greatly appreciated.
