asterisk users - May 2007 - There is no tone on an outgoing call

Hello, everyone.
I'm having a strange problem with my asterisk. After dialing and before
the other side picks up the phone I should hear the tones (I'm not sure
what are they called: piiiiiiiiiiii---piiiiiiiiiiiiii....) and in almost
all cases that is true. However there is a range of numbers where I'm
having this problem. There is no tones, just silence, until someone
picks up the phone. This does not occur when I call to those numbers
with a mobile or regular PSTN phone.
Has anyone experienced anything similar? Where I should be looking to
correct this?
Thanks in advance

P.S. I'm using asterisk 1.2.18. The Dial command is the same for all
calls: _X.,n,Dial(SIP/${EXTEN}@provider-out,45)

If it's working for most numbers and these few then I would suggest it's
an
issue at the other end and not yours.

Try using:  _X.,n,Dial(SIP/${EXTEN}@provider-out,45,r)

    r    - Indicate ringing to the calling party. Pass no audio to the calling
           party until the called channel has answered.

It's possibly what your mobile and PSTN supplier do themselves...

Same thing here for some calls (randomly, seems not to depend on the
number called, but I do not keep statistics of it). I have been to lazy
to investigate (it seems only my personal SIP provider does this, but
the other SIP lines my * is connected to) -- I think there is a Dial()
option that makes sure that a "ringing" sound is provided even if the
upstream provider does not send it. See the voip-info.org page about
Dial(), it should be covered there.
