Tested Switches:
|
|
================
|
|
Siemens EWSD - (ITU style) MTP2 and MTP3 comes up, ISUP inbound and outbound calls work as well.
|
|
DTI DXC 4K - (ANSI style) 56kbps link, MTP2 and MTP3 come up, ISUP inbound and outbound calls work as well.
|
|
Huawei M800 - (ITU style) MTP2 and MTP3 comes up, ISUP National, International inbound and outbound calls work as well, CallerID presentation&screening work.
|
|
and MORE~!

|
Thanks:
|
|
=======
|
|
Mark Spencer, for writing Asterisk and libpri and being such a great friend and boss.
|
|
|
|
Luciano Ramos, for donating a link in getting the first "real" ITU switch working.
|
|
|
|
Collin Rose and John Lodden, John for introducing me to Collin, and Collin for the first
|
|
"real" ANSI link and for holding my hand through the remaining changes that had to be
|
|
done for ANSI switches.
|
|
|
|
To Use:
|
|
=======
|
|
In order to use libss7, you must get at least the following versions of DAHDI and Asterisk:
|
|
DAHDI: 2.0.x
|
|
libss7: trunk (currently, there *only* is a trunk release).
|
|
Asterisk: 1.6.x
|
|
|
|
You must then do a `make; make install` in each of the directories that you installed
|
|
in the given order (DAHDI first, libss7 second, and Asterisk last).
|
|
|
|
NOTE: In order to check out the code, you must have the subversion client installed. This
|
|
is how to check them out from the public subversion server.
|
|
|
|
These are the commands you would type to install them:
|
|
|
|
`svn co http://svn.digium.com/svn/dahdi/linux/trunk dahdi-trunk`
|
|
`cd dahdi-trunk`
|
|
`make; make install`
|
|
|
|
`svn co http://svn.digium.com/svn/dahdi/tools/trunk dahdi-tools`
|
|
`cd dahdi-tools`
|
|
`./configure; make; make install`
|
|
|
|
`svn co http://svn.digium.com/svn/libss7/trunk libss7-trunk`
|
|
`cd libss7-trunk`
|
|
`make; make install`
|
|
|
|
`svn co http://svn.digium.com/svn/asterisk/trunk asterisk-trunk`
|
|
`cd asterisk-trunk`
|
|
`./configure; make; make install;`
|
|
|
|
This should build DAHDI, libss7, and Asterisk with SS7 support.
|
|
|
|
In the past, there was a special asterisk-ss7 branch to use which contained the SS7 code.
|
|
That code has been merged back into the trunk version of Asterisk, and the old asterisk-ss7
|
|
branch has been deprecated and removed. If you are still using the asterisk-ss7 branch, it
|
|
will not work against the current version of libss7, and you should switch to asterisk-trunk
|
|
instead.
|
|
|
|
CONFIGURATION:
|
|
In /etc/dahdi/system.conf, your signalling channel(s) should be a "dchan" and your bearers should
|
|
be set as "bchan".
|
|
|
|
The sample chan_dahdi.conf contains sample configuration for setting up an E1 link.
|
|
|
|
In brief, here is a simple ss7 linkset setup:
|
|
|
|
signalling = ss7
|
|
ss7type = itu ; or ansi if you are using an ANSI link
|
|
|
|
linkset = 1 ; Pick a number for your linkset identifier in chan_dahdi.conf
|
|
|
|
pointcode = 28 ; The decimal form of your point code. If you are using an
|
|
; ANSI linkset, you can use the xxx-xxx-xxx notation for
|
|
; specifying your linkset pointcode.
|
|
adjpointcode = 2 ; The point code of the switch adjacent to your linkset
|
|
|
|
defaultdpc = 3 ; The point code of the switch you want to send your ISUP
|
|
; traffic to. A lot of the time, this is the same as your
|
|
; adjpointcode.
|
|
|
|
; Now we configure our Bearer channels (CICs)
|
|
|
|
cicbeginswith = 1 ; Number to start counting the CICs from. So if DAHDI/1 to
|
|
; DAHDI/15 are CICs 1-15, you would set this to 1 before you
|
|
; declare channel=1-15
|
|
|
|
channel=1-15 ; Use DAHDI/1-15 and assign them to CICs 1-15
|
|
|
|
cicbeginswith = 17 ; Now for DAHDI/17 to DAHDI/31, they are CICs 17-31 so we initialize
|
|
; cicbeginswith to 17 before we declare those channels
|
|
|
|
channel = 17-31 ; This assigns CICs 17-31 to channels 17-31
|
|
|
|
sigchan = 16 ; This is where you declare which DAHDI channel is your signalling
|
|
; channel. In our case it is DAHDI/16. You can add redundant
|
|
; signalling channels by adding additional sigchan= lines.
|
|
|
|
; If we want an alternate redundant signalling channel add this
|
|
|
|
sigchan = 48 ; This would put two signalling channels in our linkset, one at
|
|
; DAHDI/16 and one at DAHDI/48 which both would be used to send/receive
|
|
; ISUP traffic.
|
|
|
|
; End of chan_dahdi.conf
|
|
|
|
This is how a basic linkset is setup. For more detailed chan_dahdi.conf SS7 config information
|
|
as well as other options available for that file, see the default chan_dahdi.conf that comes
|
|
with the samples in asterisk. If you would like, you can do a `make samples` in your
|
|
asterisk-trunk directory and it will install a sample chan_dahdi.conf for you that contains
|
|
more information about SS7 setup.
|
|
|
|
For more information, please use the asterisk-ss7 or asterisk-dev mailing
|
|
lists (I monitor them regularly) or email me directly.
