Add DAHDI Trunk

Trunk Settings
Outbound Caller IDCaller ID for calls placed out on this trunk

Format: "caller name" <#######>. You can also use the magic string 'hidden' to hide the CallerID sent out over Digital lines ONLY (E1/T1/J1/BRI/SIP/IAX):
Never Override CallerIDSome VoIP providers will drop the call if you try to send an invalid CallerID (one you don't 'own'). Use this to never send a CallerID that you haven't explicitly specified in this trunk or in the outbound callerid field of an extension/user.

:
Maximum ChannelsControls the maximum number of outbound channels (simultaneous calls) that can be used on this trunk. Inbound calls are not counted against the maximum. Leave blank to specify no maximum.:

Outgoing Dial Rules
Dial RulesA Dial Rule controls how calls will be dialed on this trunk. It can be used to add or remove prefixes. Numbers that don't match any patterns defined here will be dialed as-is. Note that a pattern without a + or | (to add or remove a prefix) will not make any changes but will create a match. Only the first matched rule will be executed and the remaining rules will not be acted on.

Rules:
X    matches any digit from 0-9
Z    matches any digit from 1-9
N    matches any digit from 2-9
[1237-9]  matches any digit or letter in the brackets (in this example, 1,2,3,7,8,9)
.    wildcard, matches one or more characters (not allowed before a | or +)
|    removes a dialing prefix from the number (for example, 613|NXXXXXX would match when some dialed "6135551234" but would only pass "5551234" to the trunk) +    adds a dialing prefix from the number (for example, 1613+NXXXXXX would match when some dialed "5551234" and would pass "16135551234" to the trunk)

You can also use both + and |, for example: 01+0|1ZXXXXXXXXX would match "016065551234" and dial it as "0116065551234" Note that the order does not matter, eg. 0|01+1ZXXXXXXXXX does the same thing. :

Dial Rules Wizards Always dial with prefix is useful for VoIP trunks, where if a number is dialed as "5551234", it can be converted to "16135551234".
Remove prefix from local numbers is useful for DAHDI trunks, where if a local number is dialed as "6135551234", it can be converted to "555-1234".
Lookup numbers for local trunk This looks up your local number on www.localcallingguide.com (NA-only), and sets up so you can dial either 7 or 10 digits (regardless of what your PSTN is) on a local trunk (where you have to dial 1+area code for long distance, but only 5551234 (7-digit dialing) or 6135551234 (10-digit dialing) for local calls
:
Outbound Dial PrefixThe outbound dialing prefix is used to prefix a dialing string to all outbound calls placed on this trunk. For example, if this trunk is behind another PBX or is a Centrex line, then you would put 9 here to access an outbound line. Another common use is to prefix calls with 'w' on a POTS line that need time to obtain dial tone to avoid eating digits.

Most users should leave this option blank.:
