Register String
Most VoIP providers require your system to REGISTER with theirs. Enter the
registration line here.
example:
username:[email protected].
Many providers will require you to provide a DID number, ex:
username:[email protected]/didnumber in order for any DID matching
to work.
Codec
Allow specified codecs, the available codecs are on the left options bar and the selected
on the right.
Advanced
Outbound CallerID
CallerID for calls placed out on this trunk
Format:
<#######>
. You can also use the format: “hidden”
<#######>
to hide the
CallerID sent out over Digital lines if supported (SIP/IAX).
CID Options
Determines what CIDs will be allowed out this trunk. IMPORTANT: EMERGENCY
CIDs defined on an extension/device will ALWAYS be used if this trunk is part of an
EMERGENCY Route regardless of these settings.
Allow Any CID:
all CIDs including foreign CIDS from forwarded external calls will
be transmitted.
Block Foreign CIDs:
blocks any CID that is the result of a forwarded call from off the
system. CIDs defined for extensions/users are transmitted.
Remove CNAM:
this will remove CNAM from any CID sent out this trunk
Force Trunk CID:
Always use the CID defined for this trunk except if part of any
EMERGENCY Route with an EMERGENCY CID defined for the extension/device.
Intra-Company Routes will always transmit an extension’s internal number and name.
Maximum Channels
Controls the maximum number of outbound channels (simultaneous calls) that can be
used on this trunk. To count inbound calls against this maximum, use auto-generated
context: from-trunk-[trunkname] as the inbound trunk’s context. (see
extesions_additional .conf)Leave blank to specify no maximum.
Type
Asterisk connection type, usually friend for endpoint.
Outbound Dial
Prefix
The 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.
Qualify
Setting to yes (equivalent to 2000 msec) will send an OPTIONS packet to the endpoint
periodically (default every minute). Used to monitor the health of the endpoint. If delays
are longer then the quality time, the endpoint will be taken offline and considered
unreachable. Can be set to a value which is the msec threshold. Setting to no will turn
this off. Can also be helpful to keep NAT pinholes open.
Qualifyfreq
Frequency in seconds to send qualify messages to the endpoint.
Nat
NAT seting, see Asterisk documentation for details. Yes usually works for both internal
and external devices. Set to No if the device will always be internal.
