I have been having problems dialing into Verizon conferencing using my * system. If i dial using a POTS line directly, the dtmf codes for the conference room are recognized with no issues, however, verizon doesnt recognize the keys when i press them as being a valid code. I remember something a while back (unfortunately - lost all my IMAP email) - Something about verizon lines and dtmf and asterisk... I have tried voipjet, goiax, teliax, all with no happyness. I am using a sipura 1001, with ulaw encoding. My dsl line is 768 up and 3200 down. Ben
