Well, what is actually happening? Call comes in on BR1 router, tries to ring a phone (on the CCM cluster) at BR1, RNA, gets forwarded to VM...
OK. Who is calling VM? the Phone at BR1 that CFNA to VM? Or the gateway? >From an IP perspective, the call leg is terminated and initiated by the GW, not the phone at BR1... So, we will then have RDNIS back out the GW to HQ and to Unity... My question is, will this RDNIS get passed to Unity when the call is redirected and will it go to the right mailbox. >From Unity's perspective, the original called party is the Unity pilot, as the GW is initiating that call leg... How do we get that call into the right mailbox???? Jonathan On Thu, Apr 17, 2008 at 8:53 AM, Juan Lopez Hernandez -X (jlopezhe - IBM - INS at Cisco) <[EMAIL PROTECTED]> wrote: > > Ah !
