We're using hunting line with 4 pstn line into office pansonic hunting pbx + 10 handset extension, as below description, all incoming phone line will join into "elasix" with "IVR" & to enable voice message box, we want to keep existing extension to hunting pbx & all others new extension will create at IPPBX system but both can communicate together & dial out too.
Our idea is all incoming pstn line -> ippbx -> ivr ->ippbx extension (e.g. ext. 110 - 130) or -> hunting pbx -> extension (e.g. 100 - 109). ->all can dial out & dial intercom + voice message enable
Thanks, is it needed to add RJ11 splitter for handset or panasonic pbx collection?
By the way, if we change phone line incoming by DDI method, what's model we should pick? And what's hardware requirement for "Elastix" is needed? And also, would it available combine with hunting line + DDI line into a system? If so, what's model will need?
