asterisk users - Mar 2008 - Call deflection on ISDN PRI in Sweden

Hello List!

 

We're having trouble making call deflection on ISDN PRI. We would like to
transfer a call to an external extension but keeping the callerid of the caller
so it can be presented to the receiver of the transferred call.

At the time we're using Zaptel 1.4.5.1, Asterisk 1.4.11 and Digium hardware
TE420B. We've ordered the service (CD) from the phone company.

 

The zapata.conf file inlcludes: 

Transfer= yes

Facilityenable=yes

Callerid=asreceived

 

In extensions.conf we try to transfer a call to an external extension as:
Transfer(ZAP/g0/ xxxxxxxx) but that fails with the ${TRANSFERSTATUS} =
UNSUPPORTED.

 

Ideas anyone? We would really appreciate it!

 

 

Kind regards,

 

Hanna

That supplementary service (CD) is not supported in libpri right now, so 
that would be the reason why it doesn't work.  The Transfer() 
application is for analog lines, IIRC.

*CLI> show application Transfer

  -= Info about application 'Transfer' =-

[Synopsis]
Transfer caller to remote extension

[Description]
  Transfer([Tech/]dest[|options]):  Requests the remote caller be transferred
to a given destination. If TECH (SIP, IAX2, LOCAL etc) is used, only
an incoming call with the same channel technology will be transfered.
Note that for SIP, if you transfer before call is setup, a 302 redirect
SIP message will be returned to the caller.

The result of the application will be reported in the TRANSFERSTATUS
channel variable:
       SUCCESS      Transfer succeeded
       FAILURE      Transfer failed
     ***  UNSUPPORTED  Transfer unsupported by channel driver ***


So what you need to do is use app_dial instead of app_transfer.
Everything else should be able to remain the same.
