I need to put together a two site, two UC500 based system and this is something I haven't done before. Looking for some tips on how to best architect this. One site is significantly larger than the other (64U UC500 and 16U UC500) and both will have PRI PSTN connections and QoS enabled MPLS data circuits between them. I guess I would start with the dialing plan. Should I use 3 or 4 digit extensions? What other issues will I have to deal with and/or plan for?
SIP and H323 dial peers are actually very similar - the only difference is that SIP dial peers have the 'session protocol sip' command. The default is H323.
