Paid on delivery
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

I'll do it using CSipSimple Opensource SIP stack, but take note that G729 requires licensing, and costs 10$/channel so it may not be something you want to ship along. SIP clients which support g729 offer it as a premium feature (check bria). regarding IPSEC, it's security at IP level, meaning it's only configured at app level, but should be available at OS level to work. If your aim with tunnel is to bypass firewall restrictions, you can do it in other ways using OpenSSL for instance, or even having the client connect to different ports/url/protocols (TCP/TLS/UDP). If the aim in security is to avoid traffic being sniffed, you can use secure SIP, along with zrtp for secure media. to avoid giving user SIP credentials, it can be implemented using REST services hosted on apache/iis. The SIP client never sends the password over the wire to the pbx, so it can't be sniffed afterwards. I can consider doing this over IOS, for similar cost.
