[asterisk-ss7] Force out-bond call to specific CIC

[Rafael Prado Rocchi]

Hi,
I'm considering you are using libss7 implementation, you can access CIC directly using the same syntax dahdi uses to direct access channels.

Syntax:
Dial(dahdi/2/${your_destination})
Dial(dahdi/15/${your_destination})


Pointing to dahhi channel-number directly.
You must first assign "CIC numbers" ->  to "Dahdi channels" in chan_dahdi.conf



example chan_dahdi.conf  (parts are missing to focus on CIC mappings)

signalling=ss7
ss7type=itu
linkset=1
networkindicator=national
pointcode=0-0-1
adjpointcode=0-0-2
sigchan=24

cicbeginswith=1
channel=1-23  ; (Add DAHDI/1 to DAHDI/23 to linkset 1 and maps them from CIC 1 to CIC 23)



Here is another example:

linkset=1
pointcode=12251
defaultdpc=6332

cicbeginswith=34
channel=2-31
cicbeginswith=66
channel=33-62
cicbeginswith=98
channel=64-93


This will result:

*CLI> ss7 show cics 1

[ Dial dahdi/3 and you will be using CIC 35 ]


Examples above are from this list (about 3 years ago). Currently I don't know about SS7 implementation on recent asterisk versions, and maybe something could be changed.
For past versions based on libss7 , you can use like this.

Hope the information helps.

What asterisk version and ss7 based implementation are you using?

Assunto: [asterisk-ss7] Force out-bond call to specific CIC

Hi
How is it possible to use Dial application to force out-bond call use "specified channel" number in one E1 or specified CIC (SS7) ?
