I'm troubleshooting a particularly annoying DTMF issue in that, It seems to mostly effect inbound long distance calls. And seems to work fine from every test set I can seem to get my hands on. Anyways, The test is quite simple. I've setup two phone numbers, 321-205-1709, And 321-302-7797. Both numbers answer and play back a sound file saying "Please dial extension 106". Upon dialing ext 106, You'll be presented with a "The test was successful" voice playback and the call will hangup. In any event that anything but 106 is heard. It'll play "That's not a valid extension" and hangup. If anyone is willing to test for me, Please report back the results when calling both numbers. The number you called from, And the carrier you terminated the call with. I appreciate the assistance! Nick Olsen Sr. Network Engineer Florida High Speed Internet (321) 205-1100 x106
