<p class=MsoNormal>Do I have to use T38 for this to work then, the gateway
is already set up for modem passthrough as the calls come from the CUCM to the
gateway and faxing from elsewhere is working fine, it's just the faxes that
originate across the SIP trunk that do not work.<o:p></o:p></p>

<div>
<p>We are having some issues with faxing over a SIP trunk, the setup is Nortel
CS1000 > SIP Trunk > CUCM 6.1. All outbound calls from the CS1000 are
routed to go out of a gateway connected to the CUCM, phone calls are fine but
faxes are working, the calls are getting to the gateway and you hear the fax
machine answer and get fax tone for about a second then it cuts off. The debug
on the gateway shows normal call clearing and no errors.<o:p></o:p></p>
</div>
<div>
<p> <o:p></o:p></p>
</div>
<div>
<p>Does anyone have any experience of this sort of set up? or any useful
troubleshooting tips.<o:p></o:p></p>
