<li><font class="Apple-style-span" face="verdana, sans-serif">More Flexible</font></li><li><font class="Apple-style-span" face="verdana, sans-serif">More Features</font></li></ul><div><font class="Apple-style-span" face="verdana, sans-serif">I'm starting to think that for our company there would be a mixture of deployments most would be just a simple one time configuration of Cisco Unified SRST. Then for some more complex sites we could utilise the features of CME in SRST. For example reception consoles for us are not setup in a DR architecture so we could utilise CME in SRST mode to have the reception phone register to CME with the pilot number instead of just its line numbers.</font></div>
</div><div><font class="Apple-style-span" face="verdana, sans-serif"><br></font></div><div><font class="Apple-style-span" face="verdana, sans-serif">If we are running less than 240 phones off a SRST router would Cisco Unified SRST and CME in SRST with the "srst mode auto-provision none" command essentially in the simplest form be the same thing?</font></div>
<div><font class="Apple-style-span" face="verdana, sans-serif"><br></font></div><div><font class="Apple-style-span" face="verdana, sans-serif">The only caveat I see with CME in SRST is that if someone saves the config while in fallback the ephone-dn config etc is saved to the running config which when switch back occurs would make the calls terminate at the SRST router not CUCM and the registered phone.</font></div>
<div><font class="Apple-style-span" face="verdana, sans-serif"><br></font></div><div><font class="Apple-style-span" face="verdana, sans-serif">Just weighing up the possibility of making all our SRST routers "CME in SRST mode".</font></div>
<div><font class="Apple-style-span" face="verdana, sans-serif"><br></font></div><div><font class="Apple-style-span" face="verdana, sans-serif">Any thoughts would be appreciated.</font></div><div><font class="Apple-style-span" face="verdana, sans-serif"><br>
