asteriskami - Asterisk How to play announcement without calling party -

i have following task asterisk, , don't know how solve it.

i have context own default extension

[my-context] exten => s,1,answer()         same => n,dial(sip/817,10,ttwwa(demo-congrats))         same => n,hangup() 

i run originate command in cli, or in ami via telnet.

originate sip/814 extension s@my-context 

it's simple , works in sequence:

1. sip/814 ringing
2. i answer sip/814
3. sip/817 ringing
4. another guy answers sip/817
5. playing announcement @ sip/817
6. hangup

but not match requirement yet, don't want calling party (sip/814 in case) join sequence @ all, want give called party (sip/817) announcement , that's it, don't know how stuff.

btw, when called party dahdi source (eg dahdi/1/${my-cellphone-number}), announcement played before accept call, can hear end part of announcement. how fix that?

any appreciated

you should trigger enother call, using call files or other technics

in call should 1 leg connect sip/817, other leg dialplan extension expected playback message.

you can trigger external script place call system command or create deamon listen event/place calls on condition(ami/events used)
