    has anyone noticed this problem before?
    I'm using 124-15.T10 on a 3725 running CME with SIP phones. I wrote a script which is supposed to collect digits but every digit recieved is duplicated.. ie if the user presses "6",  "66" shows up in the digitcollection debugs. how can i resolve this?  Relevant parts of the config are here...
    voice register global
     mode cme
     source-address x.x.x.x port 5060
    load 3911 SIP3951.8-1-1b
     application debitcme

    Hi Leon,

    I don't think any issue with TCL Script looks like issue with either sip phone or firmware please contact Cisco TAC Support they will help you.
