I previously wrote about how CM determines proper inbound call delivery (inc-call-handling-trmt), but might loosely be considered the DID -> Extension association. But… the inc-call-handling-trmt tables only tell CM how to figure out which extension to which a call should be delivered; they don’t actually associate DIDs with extensions. So how does CM determine the outbound calling party number when a station/extension makes an outgoing call? Enter public-unknown-numbering.
Ever wanted to be able to echo a calling party’s phone number back to them, in much the same way a telco-provided ANI/ALI line does? Here’s a way to do it using the ANI as presented to your PBX by the PSTN.
There are a lot of vector steps, and a lot of announcements required. For the announcements specifically – the announcements that are named with only digits are simply those spoken digits (I haven’t bothered customizing this for inflection).
Incoming call handling treatment is the administrative function used to instruct CM how to route incoming calls traversing specific trunks.
Errors/alarms of maintenance name “NR-CONN” indicate a network-region connectivity failure.
There are (hopefully rare) times when a telecom admin needs to get remote access to on-net dialtone of his Avaya Aura CM PBX. You can accomplish this via remote-access functionality.
