IAX SIP VOIP Softphone

This project is only for those freelancer that has existing similar app to amend for us.

Do you have IAX SIP VOIP Softphone system and apps? We would like to do similar system like www . zoiper . com

Zoiper is a phone solution perfectly fit for end users, service providers, call centers or any business willing to benefit from VoIP communications.

Zoiper softphone is a standalone client-side software VOIP phone application and is not bundled together with a voip service. To make and receive voip calls using Zoiper, you must subscribe to any SIP or IAX based service provider across the globe. But for our amendment, do fix the system to our SIP service provider that I will provide you. We do not open for public SIP service provider and only for our own provider.
