Hi,
Anybody please help me to enable the call waiting tone on yate through call routing module.
Where while call routing i would verify whether user is available to receive incoming calls or not, then send a call to SIP agent on both case. If user already on call they will get notifies on their second line. But however want to notifies the ISDN caller as well as User was busy on another call without using any custom music file play on their channel.
Version :
Yate - 6.0.1
Technology ; SIP
Trunk : ISDN E1 PRI
Card : Digium E1 PRI Card.
Methods are described here :
