Hi Nick,

Thanks for your reply

But the problem still exist

If you're still having problems you may not be able to get the rate of the machine.

Chances are it's using V.30 or V.32 speeds, which are not officially supported on the DSPs.

You can sometimes get speeds higher than 14400 on the DSPs, but it's best effort.

If you drop the speed down on the modem you should be alright.

The previous suggestions are really all you can hope for if there isn't any packet loss or jitter in the call.

hth,

nick

CC machines usually use very slow speed also to improve connection time.

Can you take "show controllers E1" on the PRI ?

Hi,

So I won't be able to have my visa machines on the VGs without changing its rate ?

Also please find:

VoiceGW-1#sh control e1

E1 0/0/0 is up.

Applique type is Channelized E1 - balanced

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20060707, FPGA: 13, spm_count = 0

Framing is CRC4, Line Code is HDB3, Clock Source is Line.

CRC Threshold is 320. Reported from firmware is 320.

Data in current interval (831 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

1 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

You need to configure

network-clock-participate wic 0

network-clock-select e1 0/0/0

That alone might not solve the issue but please try as well.

Then using a regular phone off the VG you should collect info from "show call voice" to see if there is any loss or jitter in the network.

And, I would try h323 for the FXS port.

Hi Paolo,

Thanks for your reply

I'll try it and feed you back

Also can i use h323 for a specific port on an sccp VG

I though for using MGCP for a specific port but found that i add the VG as sccp on the cucm, so don't follow on this

Thanks & Best Regards
