Asterisk connection with Mobile phone using Chan_Mobile

Hey.. Below are the simple steps to configure chan-mobile for asterisk to use mobile phone as outgoing trunk
The system i have used is as follow

OS: OpenSuse 12.2
Asterisk Version:certified-asterisk-1.8.11-cert8
Mobile Phone: Nokia C1-01

Step 1:

Download and and unzip asterisk into a folder

Step 2:

(a) ./configure –disable-xmldoc
(b) make menuconig ( goto Addon and select chan_mobile and save) as shown  below

Asterisk Module and Build Option Selection
**************************************************

Press ‘h’ for help.

— extended —
[*] chan_mobile
[ ] chan_ooh323
[ ] format_mp3
[ ] res_config_mysql
— deprecated —
[ ] app_mysql
[ ] app_saycountpl
[ ] cdr_mysql

(c) run make
(d) run make install
(e) run make samples

Step 3:

Make sure you have bluez pakage install if not run yum install bluez*

Step 4:

In Step 4 we will try to make sure that the bluetooth device is working on the system run command

hcitool dev

linux-ensr:/ # hcitool dev
Devices:
hci0    90:00:4E:99:7F:60

Note: my bluetooth adapter MAC address is 90:00:4E:99:7F:60 and I will be using it later in below steps

You should get an output like given below where hci0 is the bluetooth interface if you have connected to bluetooth then you should see output like below

linux-ensr:/ # hcitool dev
Devices:
hci1    BB:4A:BB:33:31:51
hci0    90:00:4E:99:7F:60

Step 5:

Now in this step we need to configure asterisk to listen to the available bluetooth device that is hci0. Goto /etc/asterisk/ and edit file chan_mobile.conf and add the following line under [general]

[adapter]
id=internal ( ID could be anything you want)
address=90:00:4E:99:7F:60

In this step we have defined the available bluetooth adapter for Asterisk to listen if you have more then two adapter add them accordinly with different ID and ofcourse MAC address

Now Asterisk is ready to detect available bluetooth devices since we have configured it to use the bluetooth device

Step 6:

As in Step 5 we have already configured Asterisk to use the available bluetooth now its time to scan the available mobile devices using Asterisk console. We will goto asterisk console using command asterisk -rvvvvv

Once inside the console type the command

linux-ensr*CLI> mobile search

This command should give you result something like this

linux-ensr*CLI> mobile search
Address                         Name                         Usable     Type                    Port
00:25:47:36:D8:C0   Nokia 5130c-2         Yes           Phone                 13
78:2E:EF:9C:3D:5E  Red                            Yes            Phone                 13

So now we have two usable devices in this example we will be using mobile device name Red ( its a nokia c1-01 mobile phone)

Note the mac address and port of the phone we will be using it in the next step

Step 7:

Edit the same file chan_mobile.conf as done in Step 5 earlier. Now we will add the details of Mobile phone taken in step 6

Simplpy add the following lines at the end of the conf file

[red]
address=78:2E:EF:9C:3D:5E
port=13
context=incoming-mobile
adapter=internal ===> This Adapter ID internal we hav already defined in step 5
group=1

Save and exit from the file

Step 8:

Now its time to pair the mobile phone with the system bluetooth adapter

use avabile GUI for bluetooth pairing to connect the mobile phone with system as shown in image below

Step 9:

Once paried goto asterisk console by typing asterisk -rvvvv and then restart asterisk by typing core restart now

Step 10:

Go back to asterisk console again by typing asterisk -rvvv once its loaded asterisk will try to connect to already paired mobile devie

Asterisk will try to initiate the connect if prompted on mobile / system for pairing accept it. You should see something like this on console

— Bluetooth Device red has connected, initializing…
— Bluetooth Device red initialized and ready.

Once connected you can run the command to see the status

Run the command mobile show devices on asterisk console

linux-ensr*CLI> mobile show devices
ID              Address           Group Adapter         Connected State      SMS
red             78:2E:EF:9C:3D:5E 1     internal        Yes       No Service No

If Connected status is YES it means you are ready to goto the next step

Step 10:

We will create the Dial plan now to make call go throug the mobile. Goto /etc/asterisk/extensions.conf and add the following lines at the end of the configuration file

[test]
exten => _X.,1,Dial(Mobile/red/${EXTEN},45)
_X.,n,Hangup

Herer red is the name of the mobile that I mentioned above in chan_mobile.conf in step 7

Save and exit

Step 11:

After making the dialplan now we have to create a sip account to make a test call designated for dial plan named [test]

Goto /etc/asterisk/sip.conf and edit it. Add the following lines at the end of the configurtion file

[test]
type=friend
host=dynamic
secret=test
dtmfmode=rfc2833
canreinvite=yes
nat=yes
qualify=yes
context=test

Save and exit

Step 12:

That is the final step simply use any sip dialer of your choice and use the credentials we defiened about in step 11 and make a test call

On asterisk console you should see call going to the mobile name (mine case its red )

== Using SIP RTP CoS mark 5
— Executing [03249255604@test:1] Dial(“SIP/test-00000000”, “Mobile/red/03249255604,45″) in new stack
— Called Mobile/red/03249255604

I think I pretty much tried to make it simple and easy. Asterisk Chan-Mobile does support more then two mobile phones that require some additional steps that I have not covered here, I run this knowledge sharing for free however small donations are always welcome.

If you are looking for more then one mobile solution please send me message or comment down to discuss
