This post describes the requirement of creating a SIP phone application on android over the same codecs as WebRTC ( PCMA , PCMU , VP8) . In my project concerning the demonstration of WebRTC inter operability ( presence , audio / video call , message )  with a native android client , I had to develop a lightweight Android SIP application , customized for the look and feel of the webrtc web application . This also enables the added services to WebRTC client such as geolocation , visual voice mail , phonebook , call control options be set from android application as well .

Aim :

Android webrtc- sip client development , using sipml5 stack implemented through web services and native android programming .  

Software Used:

⦁ Eclipse IDE
⦁ Java SE Development Kit 7.0
⦁ Android SDK

Tasks :

⦁ Authorization of a user, based on his/her credentials (Database local to the application).

⦁ Navigation Drawer on the home page which shows a menu giving the user various options like:
⦁ View Home Page
⦁ View Contact List
⦁ View/Edit My Profile
⦁ View My Location
⦁ Sign Out

⦁ Phonebook sync : Importing contact list of the Android Phone into the application. Editing user profile with values like  User Name ,  Password ,  Domain. 

⦁ Inclusion of a Web View in the application which currently opens the desired webpage(http://sipml5.org/call.htm).

⦁ Geolocation: Showing marker for the current location of user in Google Maps.Displaying the address of the user in a Toast Message.

⦁ Audio / Video call capability

Future Roadmap:

⦁ Connecting the application to a database which sits on the cloud.
⦁ Based on the entries in the database the user will be able to:
⦁ Login to the application.
⦁ View or edit his/her details in the My Profile Section.
⦁ Understanding codes of sample applications for making SIP calls from Android OS like:
⦁ SipDroid
⦁ SipDemo
⦁ IMSDroid
⦁ Modifying the existing application to be able to make SIP calls like one of the apps listed above.

Modules :

Development Done:

1. Development of an authorization page connecting the application to a local database from where values are inserted and retrieved.
2. Development of navigation drawer where additional options for the application will be displayed making it a user friendly application.

Development Planned:

1.Connectivity to a cloud database.  

2. App engine on cloud.

3. Importing contacts from phone address book .

4. Offine storage of profile details and few call logs .
