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: 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) ?

Regards
