<p class=MsoNormal>I have 3-4 smaller sites running CME 3.0 and a larger site
with CallManager 6.1 BE. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I was thinking of setting up SIP trunks between them with
specific 4-digit extension route patterns.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any caveats (eg CME 3.0 version upgrade) with this? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>They have a lot of firewalls and I thought that H323 trunks might
have issues with the firewalls.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Should be Device Trunk in CallManager and SIPv2 dial-peers
in CME 3.0.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I assume this would work but never tried it, search on CCO
didn’t find this exact setup.<o:p></o:p></p>
