when placing a call with a cellphone to the asterisk server, the dtmf recognition on asterisk is not working properly. It seems to duplicate the first digit so if I enter 123 on my cellphone, asterisk interprets it as 1123. I have messed around with relaxdtmf, & toneduration. Calling from a landline or a sip phone works pefectly with no problems. I am using a digium tdm400 card with 2 fxo ports on asterisk 1.4.9.<br>
<br>I tested the actual dtmf sound that asterisk is picking up by dialing from a cellphone and connecting to a sip phone attached to asterisk. when I hit a button I get a brief dtmf sound, then a pause and then the full dtmf sound. <br>
<br><br>Anyone else seen this issue? Is this a bug or an incorrect configuration?<br>
