Posted: Wed Jan 15, 2014 9:12 am Post subject: [asterisk-users] How to tell Asterisk to to send Ringing sig |
|
|
Hello,
My target system is :
PSTN <---> Sip Provider <---IP/ADSL---> Router with fw/NAT <--- SIP/IP/Eth --> Asterisk <--- SIP/IP/Eth --> SIP Phones
Asterisk is configured to keep NAT connection with SIP provider open (with qualifyfreq) so I don't have any problem (yet) with either casual incoming or outgoing calls.
To work around a possible No Audio when an incoming call is forwarded to an external number (because of NAT issues), I would like to configure Asterisk so that :
whenever a call comes in from SIP trunk, Asterisk starts to play a Ringing tone (while endpoint is ringing) as an RTP flux so that router opens appropriate NAT translation.
My questions are:
1. Is the method above recommended to work around fw/NAT issues ?
2. Are the setings bellow sufficient to implement the above method (from experience, I've gathered mixed results and I would appreciate any input that would confirm I'm on the right or the wrong track) or shall add more magic somewhere (Answer(), Progress(), ...) ?
sip.conf:
progressinband=yes
prematuremedia=no
extensions.conf
exten => _X.,1,Dial(SIP/foo)

Dial(SIP/foo,45,r(ring))
Asterisk will start sending audio packets to the caller before the
callee answers.

Setting progressinband=never when you want....progress (ringing) to be sent as audio (inband) has always confused me.
Can anyone shed some light on that?

(I'm also confused, to say the least)
