i have to solve the following problem with Asterisk (Vers. 18.104.22.168) and IP Phone .
The Asterisk System is installed on Rapberry PI Model B Rev 2 with wolfson audio sound card. in Asterisk there are five SIP – phones registered. What I have to do is that the SIP Phone (Hardware not softphone) with ID “1000” should also use external loudspeaker which is connected to soundcard of Raspberry PI.
The System is only for internal communication in building network. My problem is now – how to get the same audio Signal on external speaker which is connected to the soundcard. When ID “1000” is called you should hear the voice from the other part on loudspeaker.
I m not sure how to solve problem. I have found in google some issues like dial(console/Alsa) but at the moment i don´t know how to “redirect” the audio signal (for ID “1000”) to loudspeaker and how the extensions.conf commands are.
At the moment I can call to each phone this function worked well.
I would be pleased if I could get some help .
