Asterisk & FreePBX

Asterisk 是第一套以開放原始碼軟體實作的 用戶交換機 系統。Asterisk 由 Digium 的創辦人馬克·史賓瑟於1999年他還在奧本大學念書時所開發。與其他的用戶交換機系統相同，Asterisk 同樣支援電話撥打另一隻分機，和撥打到公共交換電話網與IP電話系統。 FreePBX is a web-based open-source graphical user interface (GUI) that manages Asterisk, a voice over IP and telephony server.

sudo chown -R asterisk.asterisk /etc/asterisk
sudo chown -R asterisk.asterisk /var/{lib,log,spool}/asterisk
sudo chown -R asterisk.asterisk /usr/lib/asterisk

Set Asterisk default user to asterisk

$ sudo vim /etc/default/asterisk
AST_USER="asterisk"
AST_GROUP="asterisk"

Can't send 10 type frames with SIP write

Frame type '10' is comfort noise (aka CNG) which Asterisk does not support.

However as of 13.18.0 this message will be silenced so you won’t see it anymore.

You can ignore it or disable CNG on all of your endpoints and ask the telecom providers as well to disable the CNG on your trunks.



A2B 與 FreePBX 的連接

A2B 作為 Outbound Trunk 時

Call > FreePBX > A2B > SIP Carrier

在 FreePBX 上的設定範例：
以帳號密碼驗證方式

username=51521171
fromuser=51521171
type=friend
secret=1234567
host=incoming.future-nine.com
insecure=port,invite
nat=yes
qualify=yes
context=from-trunk
allow=ulaw,g729,g726
trustrpid=yes
sendrpid=yes
canreinvite=no

FreePBX 作為 Outbound Trunk 時

Call > A2B > FreePBX > SIP Carrier

在 FreePBX 上)
  1. 新增 SIP extension: 9001
在 A2B PBX)

1. 新增 SIP Trunk: freepbx

[freepbx]
username=9001
type=peer
secret=<ext-secret>
insecure=very
host=<freepbx-ip-addr>
fromuser=9001
qualify=yes

2. 新增 SIP Register String (for incoming call only)

9001:<ext-secret>@<freepbx-ip-addr>/from_freepbx

NOTE: 最後面為甚麼不是 SIP number 而是改用字串(/from_freepbx)呢？這是因為若以 SIP number 199 來作識別，可能會與本地的其他分機的編碼規則造成衝突，所以改用字串可以避免爾後遇到路由的問題。

3. 新增 Outbound Route

  8. Logout by clicking on image icon in upper right corner of dialog window.
Installing STT Engine

1. Unpack the file

wget http://incrediblepbx.com/sendmailibm-13.tar.gz
tar zxvf sendmailibm-13.tar.gz
cp sendmailmp3.ibm /usr/local/sbin/sendmailmp3
chmod 0755 /usr/local/sbin/sendmailmp3

2. Edit sendmailmp3.ibm and insert your IBM STT API_KEY and URL. Save file.

3. Edit bluemix-test and insert your IBM STT API_KEY and URL. Save the file.

4. Copy the updated sendmailmp3.ibm file to sendmailmp3:

cp sendmailmp3.ibm /usr/local/sbin/sendmailmp3
chmod 0755 /usr/local/sbin/sendmailmp3

5. Test your Bluemix STT setup: bluemix-test

Result should be: we are now transferring you out of the company directory…

Password protect http access

A simple way to block scanners looking for exploits on apache web servers.

mkdir -p /usr/local/apache/passwd
htpasswd -c /usr/local/apache/passwd/wwwpasswd someusername
htpasswd -c /usr/local/apache/passwd/wwwpasswd someotherusername
nano /var/www/html/.htaccess
# .htaccess files require AllowOverride On in /etc/httpd/conf/httpd.conf
AuthType Basic
AuthName "Restricted Access"
AuthUserFile /usr/local/apache/passwd/wwwpasswd
Require valid-user

Alternatively, the above .htaccess config can be added to /etc/httpd/conf/httpd.conf or as a separate file in /etc/httpd/conf.d/ as follows.

<Directory /var/www/html>
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /usr/local/apache/passwd/wwwpasswd
Require valid-user
</Directory>
Whitelist protect http access

If http access is only required from certain IP addresses.
NOTE: Apache 2.4 以後才支援這功能
Edit /etc/httpd/conf.d/whitelist.conf

<Location />
 <RequireAny>
 ## Uncomment the following line to disable the whitelist
 #Require all granted
 Require ip x.x.x.x
 Require ip x.x.x.x x.x.x.x x.x.x.x

 Require ip x.x.x.0/255.255.255.0

如果以後有修改 Settings 的內容，或者 Template Editor，完成變更後，還要到 Extension Mapping，選擇 Selected Phone Options 或者 Global Phone Options，按下 Rebuild，這樣才會套用更新到所有裝置的佈署檔。

Extension Provisioning

Add Device: Linksys PAP2T

FreePBX GUI > Settings > OSS Endpoint Manager > Package Manager

Create Template: my-pap2t

注意：預設的部署檔會將 PAP2T 的管理網頁界面關閉，新增一個部署設定檔 my-pap2t。

技巧：如果 template 內容如果有修改過，必須到 Extension Mapping 選擇分機後，重新執行一次 Save，這樣新的設定才會被套用。

FreePBX GUI > Settings > OSS Endpoint Manager > Template Manager

Edit the template: my-pap2t

注意：編輯 template 時，不要使用 Edit Global Setting Overrides，這個可能會弄壞 template。如果不小心 弄壞 template，只要將 template 移除後重建即可。

技巧：template 或者原始設定檔 (spa$mac.xml) 有修改過參數，要如何在設備部署前做驗證？以 HTTP 為例，瀏覽這段網址 http://freepbx-ip-addr/provisioning/p.php/spaxxxxxxx.xml，xxxxxxx 是設備的 MAC address （必須是小寫），可以下載部署設定檔。
