[asterisk-dev] ISDN ETSI Call Rerouting

[Klaus Darilion]

Hi!

I have Asterisk in front of an Siemens PBX which sends Call Rerouting 
messages (e.g. a user forwards incoming calls to its mobile phone).

The ETSI Call Rerouting works this way:

                                        Hicom   rerouting
Caller          Telco                   PBX     target
------SETUP-----> |
                   | ----SETUP------------>
                   |
                   | <---CALL PROCEEDING---
                   |
                   | <---FACILITY+ --------
                   |    EtsiCallRerouting
                   |
                   | ----DISCONNECT------->
                   | <---RELEASE-----------
                   | ----RELEASE COMPLETE->
                   |
                   | ----SETUP--------------------->



Thus, I would like to have Asterisk to forward the FACILITY message to 
the telco. I use Asterisk 1.2 which does not support it and AFAIK there 
is also no support for that in 1.4.

Before starting coding I want to know if there is already support for 
that (or at least for decoding/encoding the ETSI Call Rerouting) 
Asterisk 1.6 or trunk?

thanks
Klaus
