<p class=MsoNormal>Does anyone out there use a SIP trunk for PSTN and DID
routing out there?? <o:p></o:p></p>
<p class=MsoNormal>I’m considering converting one of my field offices
from a standard TDM circuit to SIP, and wanted to know if anyone could share
their experiences.<o:p></o:p></p>
<p class=MsoNormal>What are the benefits and downsides. I know it’s
supposed to allow for flexible management of your DID’s, but if
you’re using an MPLS circuit to <o:p></o:p></p>
<p class=MsoNormal>piggyback your DID’s onto and it goes down, you have
no failover, varying on how you’re configured, etc. etc..<o:p></o:p></p>
<p class=MsoNormal>and what does the config look like on the CUCM side? I
gather it’s still configured as a gateway.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Experiences, anyone?<o:p></o:p></p>
