Dear List I am testing various early audio scenarios with different voice IC's, phones and pbxes.
In Switzerland, when you operate a value added number, you have to announce the price of the call, usually in early audio, before the call is established. In 'dialplan' terms this would be: exten => XX,1,Ringing exten => XX,n,Wait(15) exten => XX,n,Progress exten => XX,n,Playback(price-announce,noanswer) exten => XX,n,Wait(5) exten => XX,n,Answer I see the asterisk playing the early announcement audio in the rtp stream. Some devices (arris EMTA) calling the asterisk also do play it to the caller. But! Most other devices I have tested just keep playing the locally generated ringtone despite getting an 183 with SDP and the announcement is never to be heard by the caller. If I do to force inband ringback tone, this works with all devices I have tested so far. exten => XX,1,Progress exten => XX,n,Ringing exten => XX,n,Wait(15) exten => XX,n,Playback(price-announce,noanswer) exten => XX,n,Wait(5) exten => XX,n,Answer Is anything wrong with the transition of ringing without SDP (to have the local device generating ringback tone) and then start sending early audio with 183? -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________ -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
