There was also the fact that it says a dial plan can be handed off to another dialplan, making their definition of the word even more confusing. ????Dialplans can be separated into contexts, allowing calls to follow different pathways for different kinds of calls. Calls can be handed-off to other contexts as well.
I found that to be a little imprecise. I checked a dozen telephony glossaries and found no listing for extension. But when searching for definitions, I got these:define the information needed for an endpoint such as a hard phone, soft phone or some other device to connect to the SIP server. The extension is the SIP username and the password is the secret used for authentication.
Noun 1. telephone extension - an additional telephone set that is connected to the same telephone line
The definition of an extension is an addition such as to a building, an extra phone line connected to the main line or an extra amount of time given to someone to pay a debt.
1Extension of the telephone network so as to connect a new town, region, etc. (now rare).
2A subsidiary telephone, either attached to the main line or on a line leading from the main switchboard in a large building.
I think I'll go with "a telephone extension may refer to a phone on an internal telephone line attached to a private branch exchange (PBX)" and "an additional telephone set that is connected to the same telephone line". Does anyone think differently?Extension (telephone)
From Wikipedia, the free encyclopedia
In residential telephony, an extension telephone is an additional telephone wired to the same telephone line as another. In middle 20th century telephone jargon, the first telephone on a line was a "Main Station" and subsequent ones "Extensions". Such extension phones allow making or receiving calls in different rooms, for example in a home, but any incoming call would ring all extensions and any one extension being in use would cause the line to be busy for all users. Some telephones intended for use as extensions have built in intercom features; a key telephone system for a small business may offer two to five lines, lamps indicating lines already in use, the ability to place calls on 'hold' and an intercom on each of the multiple extensions.
In business telephony, a telephone extension may refer to a phone on an internal telephone line attached to a private branch exchange (PBX) or Centrex system. The PBX operates much as a community switchboard does for a geographic telephone numbering plan and allows multiple lines inside the office to connect without each phone requiring a separate outside line. In these systems, one usually has to dial a number (typically 9 in North America, 0 in Europe) to tell the PBX to connect with an outside landline (also called DDCO, or Direct Dial Central Office) to dial an external number. Within the PBX, the user merely dials the extension number to reach any other user directly. For inbound calls, a switchboard operator or automated attendant may request the number of the desired extension or the call may be completed with direct inbound dialing if outside numbers are assigned to individual extensions.
An off-premises extension, where a worker at a remote location employs a telephone configured to appear as if it were an extension located at the main business site, may be created in analog telephony by using a leased line to connect the extension to the main enterprise system. Voice over IP makes the creation of off-premises extensions inexpensive and trivial as broadband Internet and virtual private networking can extend local network access anywhere in the world. In either system, an off-premises extension is reachable from within the same enterprise simply by calling its extension number directly; for inbound and outgoing calls, it functions as if it were located at the main place of business.

No, you are looking for someone who will answer you every tiny basic question which you could answer yourself by a little bit of effort and the ability to analyze errors correctly. Many people in this forum are willing to help and have expert knowledge in freeswitch, fusionpbx and general hosting on linux, but your way to ask questions is just exhausting for everyone here.Sorry to bother. Was just looking for an expert.
