In lab 10A, HQ devices are placed in DP_HQ with location HQ. GK/SIP trunk are placed in seperate DP, with location hub_none and no RSVP applied. So when calling from BR1 phone to CME over GK trunk, no CAC is enforced at the UCM. But the calls go over the FR link, as the FR setup is hub-and-spoke. Considering this topology (versus MPLS) : Shouldn't CAC be enforced (RSVP enabled on the hub_none location) to limit the amount of calls from BR1 to HQ - by extension to CME? I understand GK CAC can be used to contol the amount of calls between the UCM cluster and CME - but in this case we need to have CAC on the link BR1<> HQ too.
Also, what is the use of codec pass-through in the RSVP MTP ? Calls use g729 over the WAN (normally) - so what scenario exsits to have codec pass-through configured with g729 as fallback? why not simply use g729r8 as codec, without the passthrough (considering no video is involved here) thx for sharing thoughts!
