BlankI have a simple dial plan question and will appreciate if you guys can chip-in:
In some of the workbooks that I am using e.g. IPexpert & NLI in particular, I have seen them state questions like: HQ numbering planning: 212-221-1... BR1 numbering planning: 617-521-2... BR2 numbering planning: 331-321-3... The question will then ask that local, long distance & international calls must use the HQ gateway and if it fails, they should use the BR1 gateway.---seems harmless & the solution seems simple too and that is my problem... The solution will contain these dial plans: 9[2-9]xxxxx - local calls ->pointing to a route list containg HQ-GW & BR1-GW in that order. 9[2-9]xx[2-9]xxxxxx - long distance calls. ->pointing to a route list containg HQ-GW & BR1-GW in that order. *when the call is routed through a remote GW (e.g. DN is in HQ, but it is been routed through BR1 GW); HQ long distance dial pattern will be prefix to the dialed number... Since the same question will be repeated in the BR1 dial plan section, the solution will be the same, but the GW order will be reversed My Question: For calls originating from HQ (CCM), since those two dial plans also mactesn numbers like 221-2001 & 212-221-2001 (which are local & long distance representation of the internal DN 2001), what is the question really asking that one do? Is it: 1. Blindly send all local & long distant calls to HQ GW then BR1 GW and create a hairpin either in HQ GW or in BR1 GW to route the call back to CCM where DNs for HQ & BR1 resides? OR 2. Make the local & long distance dial patterns to be more specific such that, it will only match DNs in BR2 (which resides outside the CCM) and route that to HQ-GW and then BR1-GW.---which makes sense AND 3. Also create a translation patterns for HQ & BR1 local & long distance (e.g. for HQ 221-1XXX & 212-221-1XXX) dial patterns and strip off the leading 221 or 212-221, so that it can match the local HQ & BR1 DNs residing on the CCM.
