I“m not losing packets consistently. No errors
shown nowhere on gateway interface (Gig interface on
gateway, switch
and CCM, no errors nowhere), no duplicate IP“s
on my voice vlan. This is a intermittent problem.
I am gathering etereal sniff traces from the gateway
interface
to determine if the RTP packets are going both ways on my
end when
the problem happens. I also set up a carin voice
reccording system if I have to prove something to
the telco I can play a phonecall file for them
and compare it to the bad voice call over the PSTN.
I suspect this to be a telco issue. Rare to have it only
1 way in that world but I have seen it before though.
I“ll let you know what happens.
regards. Kristjan
p.s doesn“t seem to be a dsp issue either.

Do an extended ping, are you losing packets, are you losing
packets
consistently?
If you are, then you have a routing loop or a dupe IP....
Why do you think you don't?
