Nothing interesting there.<br><br>Okay, so you have IP phones that are setup to use G.729 over the WAN... I presume they use G.711 over the LAN, so why don't we disable dtmf-relay, use in-band and see what happens.<br>
<br>Realistically, my thinking is that there is some incompatibility between PRIs and the site you are calling... <br><br><br><br>Jonathan<br><br><div><span class="gmail_quote">On 12/20/06, <b class="gmail_sendername">Robert Kulagowski
