I am hoping I have narrowed this down to not be a HUGE mess of a message.  I am being asked to find out of these will work together on either a CDP or UDP dialing plan.

Questions:
1.  Is it supported the SIP dialing between IPO R8, BCM 450 R6 and CS1K R7?

2.  Since the last 4 numbers of extensions match on a few systems does this mean I will have to use short codes to make steering codes to the correct line groups for each site or is there a work around to make the CDP dialing work? CDP or UDP?

3.  Do I build a SIP line for each site that the IP Office is going to talk to?  

I cannot find any support documentation on anything other than SCN from IPO to IPO and basic IPO to CS1K but nothing to explain BCM450 too and whether or not we can somehow work around the matching extension numbers either using CDP or UDP.


Any help would be GREAT!  Thanks.

 

The IP Office can talk to most systems using SIP, I just built a trunk to a Mitel, so yes that is possible.

CDP and UDP sounds like Nortel terminology to me, the IP Office doesn't work like that, it uses shortcodes to route the calls, yes you would just build a trunk to each system you want to talk to.

This document is probably what you need

I think it means dialplans instead of protocols.
 

BAZINGA!

I'm not insane, my mother had me tested!

This is a older doc but will also help

You'll use a CDP dialing plan on the BCM and CS1K systems.  The only gotcha I've run into is setting the SIGO on the virtual trunk route on the CS1K to STD and not ESN5.  ESN5 seems to cause issues with calls to/from the IPO.
