Create an interconnection¶
There are two types of interconnections :
Customized interconnections are mainly used for interconnections using DAHDI or Local channels:
Name : it is the name which will appear in the outcall interconnections list,
Interface : this is the channel name (for DAHDI see DAHDI interconnections)
Interface suffix (optional) : a suffix added after the dialed number (in fact the Dial command will dial:
Context : currently not relevant
- , and tabs create the SIP peer information
- tab creates the registration chain
in XiVO PBX Web interface slash “/” character is not supported in the password field.
To use your DAHDI links you must create a customized interconnection.
Name : the name of the interconnection like e1_span1 or bri_port1
Interface : must be of the form
dahdi/[group order][group number] where :
group orderis one of :
g: pick the first available channel in group, searching from lowest to highest,
G: pick the first available channel in group, searching from highest to lowest,
r: pick the first available channel in group, going in round-robin fashion (and remembering where it last left off), searching from lowest to highest,
R: pick the first available channel in group, going in round-robin fashion (and remembering where it last left off), searching from highest to lowest.
group numberis the group number to which belongs the span as defined in the /etc/asterisk/dahdi-channels.conf.
if you use a BRI card you MUST use per-port dahdi groups. You should not use a group like g0 which spans over several spans.
For example, add an interconnection to the menu
Name : interconnection name Interface : dahdi/g0
Interesting Asterisk commands:
sip show peers sip show registry sip set debug on
When setting up an interconnection with the public network or another PBX, it is possible to set a caller ID in different places. Each way to configure a caller ID has it’s own use case.
The format for a caller ID is the following
"My Name" <9999> If you don’t set the number part of
the caller ID, the dialplan’s number will be used instead. This might not be a good option in most
If you only need to set a number as an outgoing caller ID, you just have to put the number in the caller ID field like
Outgoing call caller ID¶
There are several behavior for the outgoing caller ID.
Use outgoing caller ID¶
When the internal caller’s caller ID is not usable to the called party, the outgoing call’s caller id can be fixed to a given value that is more useful to the outside world. Giving the public number here might be a good idea.
A user can also have a forced caller ID for outgoing calls. This can be useful for a user who has his own public number (DID number). This option can be set in the user’s configuration page. For this, the Outgoing Caller ID option must be set to Customize.
The user can also set his outgoing caller ID to Anonymous.
If you use a SIP provider trunk, and if your provider supports the RFC3325 for Anonymous calls, you have to set the Send the Remote-Party-ID option of your SIP trunk to PAI:
- set parameter Send the Remote-Party-ID to PAI
With this option anonymous calls will be sent to your SIP provider with the RFC 3325 standard. Note that in this case, the P-Asserted-Identity SIP Header will contain the Outgoing caller ID number if set. Otherwise it will use the user’s internal caller id, which not a good idea. So you should configure a default caller ID in the outgoing call.
Order of precedence¶
The order of precedence when setting the caller ID in multiple places is the following.
- User’s outgoing caller ID
- Outgoing call caller ID
- Default caller ID
