Thank you so much for all the valuable input. TDS Metrocom has found some interesting information about this problem. When our fax modem goes off the hook and dial the phone number, the fax modem is dialing the entire phone number in one second. The time frame between each DTMF tone is 80 ms. So, the switch is not registering the entire dialed digits. They have a EWSD switch, and since the switch is not catching all the dialed digits, our faxes are failing. Any suggestion?

I have a question about the T1 Channel Bank. We have TDS Telecom installed a channel bank with FXS card, and connect those analog lines to key system, and fax modem. All the voice lines are perfect, but the faxes are not working properly. The fax line bypasses the key system, and connect directly to the fax card, and then to a server. Many faxes are failing everyday. Any suggestions? </font>
