as the attachement

Ver.txt  is the  show run/show version/show voice register global/show telephony-service/show voice register all /some information

8831.txt is the debug voice ccsig message when 8831 phone dialed

Any idea why it's only sending one digit

I have seen this on 7841 phones using cme. If you are using full provisioning srst then enqble digit collect kpml command on voice register pool, apply cre prof and reset the phones

tks for your reply.

i will test about the full provisioning srst mode ~~

Hello,

Configure the following:

config t

voice register pool 1

no digit collect kpml

Try making a test after this, It should work.

Rate the post accordingly.

Also your missing the following:

config t

voice register pool  1
 id network 11.31.66.0 mask 255.255.255.0
codec g711ulaw

Amazing , your method is right , i change config like this

voice register pool  1
 id network 11.31.66.0 mask 255.255.255.0

 no digit collect kpml

 codec g711ulaw

 dtmf-relay rtp-nte sip-notify
 no vad

the problem solves ! thanks a lot ~~

by the way , i search KMPL information on google , that`s a Digit collection for SIP phone , it seem that KMPL has not any problem , and 78XX phone can dial normal , why 8831 not ,is 8831 no support KMPL ?

Hi,

There are two mechanism here:

1> Digit collection

2> Digit Relay

1>

When we apply the command " no digit collect kpml" we are making sure we stop digit collection.

Secondly asking it to stop collection of the digit one-by-one for KPML. As KPML is Out-of-band DTMF.

2> Relay comes into picture once the digits have been collected.

Hope this helps..
