<br>
please be gentle with me but i can not find any help in the wiki to<br>
solve my problem<br>
this is a desperat try to get some answers to the following problem<br>
freeswitch is a configured as call back server<br>
FS originates the A-leg when answered the B-leg is originated.<br>
after A-leg has answered I like to play a short welcome message<br>
After the welcome mesage is played the international, original<br>
ringbacktone (telco carrier RBT) from the B-leg shall be passed through<br>
and the A-leg user should be able to hear it.<br>
This is important to hear some carrier specific announcements or<br>
coloured/personalized ring back.<br>
Right now we play our own ringbacktone even though the carrier provides<br>
us with a 183 sdp<br>
I did play with the usual Channel variables<br>
but as far as I understood the passing through of the ringbacktone is<br>
default behaviour.<br>
<br>
<br>
<br>
<br>
<br>
<br>

With best regards<br>
