[Asterisk-Users] Simulating Dialtone ?

[Christoph Adomeit]

Hello,

I have a tradititional PRI-PBX internally before my Asterisk Server,
it looks like this:
PSTN-PRI->ASTERISK->ALCATEL

I did not and I dont want to change my PBX Setup.

My Users are used to hear a dialtone after dialing "0" with a
phone on the Alcatel.

In my asterisk setup I use overlapped dialing, so there is
no more dialtone and that confuses my users.

Is there any Trick to simulate a Dialtone after the users dial
a "0" for an outgoing call ?

Asterisk does not see the "0", it is kept in the Alcatel and only
the numbers after the zero are sent to the asterisk-server in
overlapped mode one-by-one, "0" here means PSTN, I think many
other countries use "9" for this.

There must be some way, there is a dialtone as soon as I plug in the
Alcatel directly to the PSTN-PRI.

Thanks
  Christoph
