I have two small suggestions;
One I spent a bunch of time recently walking someone through DAHDI who had used ZAP at one time. We got to the Chanel Banked Centrex lines and setup the “ZAP Channel DIDS” module so that inbound the routing worked the way they wanted. Since this is mostly tags and context names, could we get it updated to Dahdi Channel DIDS or maybe some non technology specific label (Inward Dids)?? Spending lots of time explaining why we don’t have ZAP any longer and then telling someone to use ZAP Channel DIDs is a bit confusing.
On another note, a number of years ago Phillipe was nice enough to help me during a Huntsville class with a mod to force the outbound call to a Centrex Channel (Channel Bank slot) with a combination of a data entry in Asterisk and a modified context. This has been a big help because now the outbound PSTN call almost always goes out the trunk assigned as the Inward route so it acts like a private line in a copper world. A SIP /IAX2 solution would be better, but the customer is always right…
