[cisco-voip] Dropping RTP packets??

[Kevin Dunn]

I just spent the day recabling a cluster &^%$( wire closet at our remote
site.  H323 Gateway with 7 incoming FXO lines.  They had some static on the
lines that were clean at demark and noisy by the time they got to the 2821.
Now the lines are crystal clear (pat on back) but one line is now dropping
incoming packets (example: I say "1234567" they hear "12 45 7" it is
"sporatic and with the static so bad before it could have "always" been
happening.

On a side note thie one line is their 800# which sends all calls to IPCC.  I
am running CCM 4.1.3 (sr6) and the gateways is 2821 H323.

Voice-port configuration:

voice-port 0/1/1
trunk-group 1
input gain 3
output attenuation 1
no vad
connection plar 3999 (to IPCC)

I dont' think the issue is IPC, as there are three other lines that run the
PLAR 3999 command, and all work splendidly.

QUESTION:  How can I check dropped packets on one FXO port?
is it a debug scheme?

Thanks folks

Kevin
