<p> An analog DID trunk is a line (typically part of a group) that has a group of numbers assigned to it at the telco side. They work in a variety of ways depending on the telco. One example is the trunks as Telus provides them. The end user provides dialtone back to the telco. When a call comes in on a DID the telco picks up the first available line (remember, the customer is providing dial tone.) and dials the last 4 digits of the dialed number. They are often replaced by PRIs but in some locations a PRI is not affordable and these provide the same DID functionality for a small fraction of the price.<br /><br /> <br /><br />Darren Wiebe<br /><br />darren@aleph-com.net </p><p> </p><p> </p><blockquote>Wed Feb 13 2008 10:11:44 AM MST from Tzafrir Cohen to asterisk-users@lists.digium.com <br />Subject: Re: [asterisk-users] Analog DID<br /><br />On Wed, Feb 13, 2008 at 10:40:25AM -0600, Joe Pukepail wrote:<br /><blockquote>> Does anyone have any suggestions for connecting analog DID trunks?<br /></blockquote><br />What is an analog DID trunk?<br /><br />You want to connect phones to your Asterisk?
