<div dir="ltr">Hello all,<br><br>I've got a user out on a branch campus that is trying to use a long distance calling card from her dorm room (POTS phone), and she is unable to enter in the card number successfully after she connects to the carrier. If she moves to an IP Phone it works fine.. so I am thinking this might have something to do with DTMF tones between the VG224 and the pstn gateway. I've had then swap out her POTS phone already, didn't help.<br>
<br>VG224 ports are in SCCP mode. Anyone run into a similar problem before? Is there some specific configuration on the gateway I need to add to deal correctly with DTMF?<br clear="all"><br>-- <br>Ed Leatherman<br>Assistant Director, Voice Services<br>
