The objective of the project is to modify the existing FaxServer solution based on Hylafax and Asterisk. Current solution supports T.30 protocol with SIP Trunks and G.711 (Asterisk with IAX modems). Modified solution should provide SIP interface (SIP Trunks) with T.38 (we require the usage of Freeswitch - www.freeswitch.org). Modifications should be transparent for other system functionalities. The software to be used should be released under Open-Source License (excluding GPL,CPL).

Our company currently uses over 1,000 different VOIP local phone DID numbers. We currently pay .99 per number per month through Ringcentral. Our plan gives us the minutes we need (around 15K/month) and 5 users, a phone tree, departmental extensions, personal extensions, automatic voice recording, and softphones for around $1,500 per month. We are looking for a VOIP consultant that can get us a better way at a lower cost. In addition, We hope this person will also help us keep our 1,000 current DID numbers. Again we are looking for a way to pay less than .99 cents per number for our 1,000 local number or a way to pay one up front fee for permanent use of our current numbers. I assume that we will need to port these to the new system. We don't know if we need another VOIP provider, and SIP trunk provider, just a DID host, our own ISP license, Asterisk or WHAT?? We are not sure if there is a way to do this but are interested to find and will need help with the process. Thanks...

Zoiper: http://www.zoiper.com/en/screenshots#mobile-ios http://www.zoiper.com/en/screenshots#mobile-android Main idea is that it should be an app that can be downloaded to a smartphone through the AppStore, Google Play store. User then launches the app, goes to Settings and creates a new SIP account by entering all the information we will provide to them manually such as: Host (IP or domain name of our VOIP server) Username and Password (username and password the user will try to authenticate with against our server) And maybe some other optional settings to make sure calls get routed through. Then they hit big Register button and get authenticated by our own VOIP server we already have in place running Asterisk. After they get authenticated by the server with the given credentials they get sent to a normal dial-pad/number-pad view where they...
