Feature Phone to VoIP

Job ID: 31716360

Budget: $250 – $750 USD

Hello: We operate a VoIP telecom platform and are using it with cellular phones as well.

We have recently connected a "feature type" phone using its native dialer to our VoIP (SIP to SIP) Platform (rather than an app on a smartphone).

The phone is Android OS and does have a SIP client.

The phone has a messenger app for sms and the manufacturer has noted we could make adjustments to the apk as this is publicly available for developers.

On our VoIP side the custom application should support the SIP SIMPLE protocol for messaging. It should send outbound SIP MESSAGE to our SIP node IP xxx.xxx.xxx.xxx as well as receive inbound SIP MESSAGE from the SIP node.

This maybe helpful … https://cs.android.com/android/platform/superproject/+/android-8.1.0_r48: and dive into the phone and messages source code. The SIP stack is in the external/nist-sip folder.

Let me know what you would need. Thank you,
