Hello Rafal. By This /I don't know what is the exact difference between a pre-answerred and answerred call but one nice thing is that when you <hangup /> or <break /> in this state the call will be rejected and the caller will hear a 'busy' signal.// / /You are dealing with early_media./ https://wiki.freeswitch.org/wiki/Early_Media This is what "normally" your mobile operator uses to say stuff like , your are low on credit or , voicemail like messages at least here in Europe is pretty common. You can generally "play" with this feature inside the LAN but it your are using PSTN / GSM Networks take into consideration that the provider will generally drop your early media . Again this depends on your provider Config if its Tier 1 , 2 ,3 .... Antonio On 6/27/13 11:52 AM, Rafal Gwizdala wrote:
