Dropping RTP packets?? (Kevin Dunn)

Hello Kevin,

Can you tell me if this voice quality issue is one way or
both ways ?

I“m dealing with very similar problem with 2821 as h.323
voice gateway
connecting to PRI ISDN to Telco. There is sometimes oneway
quality issues
for outbound calls where the called party is experiencing
the same issue
that you mentioned. The IP phone user does not notice any
voice quality issues.
I have a Cisco TAC case going on and some sniffing from the
ethereal going on as the isdn debug and the PRI lines seem
good.

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

Routing loop or duplicate IP of the gateway on the network.
