Android SIP Client

Project is for an Android SIP client based on sipdroid or similar with the following features:

• Access to phone/sim contacts

• Option to set app as default dialer either when on wifi, when on local data network, or at all times (including when roaming)

• IPSEC VPN client built in

• GSM or G729 codec (G729 preferred, but battery drain must also be taken in to consideration)

• Ability for app to intercept a “wake up” call from the cellular network to re-enable data on phones with data set to turn off after a certain idle period

• Conforms to SIP RFC and correctly passes DTMF tones

• GUI will ask for username and password, that username and password will then be queried against a central database to retrieve SIP username and password – SIP credentials should not be accessible by end user

• Any other protection to prevent end user from using SIP credentials on a non-cellular device should be considered

• Must work behind NAT/private IP

• Mute/Speaker/Conference/etc

• Possible balance display functionality

• User friendly GUI with custom branding and logo

Full source code must be provided and must be written in English.
