<p class=MsoNormal>Hi everyone,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a CUCM6.01 cluster that talks to an Exchange 2007 UM
cluster over SIP. The issue I have is with T.38 faxing. I
have an eFax service which is calling into the CUCM, which is a CTI forwarded
to VM. Once the fax server hits the mailbox, it seems that MSX is not
picking up the fax tones. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>There is a known issue on the MS side that I’m looking
into, as we are on MSX07SP1. I’m going to change the setting, but I
wanted to see if there was anything I’m missing in the GW config to get
this to work properly. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Has anyone successfully gotten CM6 and MSX07 to work with
faxing? Can it even be done?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am running 12.4(15)T1 on a 2851 with MGCP. I
have ensured that T.38 is on. Show MGCP excerpt below:<o:p></o:p></p>
