    A2billing CustomerUI customiseWhen a Customer logs into their A2Billing Customer Portal Currently, their negative balance displays. Below the negative balance is a drop down to select the amount of money you want to add to your account. You select the amount and it redirects you to Paypal. Then redirects back adding the funded amount to your account. Instead of this we want when the Customer logs in to his portal he sees the negative balance and a link below to pay that negative balance amount, that says PAY BILL NOW. NOT a drop down to select an amount. This Link to Pay Bill Now should send this amount to our Authorize.net gateway and return marking the database paid.

    We want to build a very simple proof of concept to help us raise capital. The proof of concept involves developing an App and the supporting infrastructure to divert call internationally. The plan is to create the App to divert calls on the GSM network to a local PSTN to VoIP gateway. The server will than route the calls to another server located in the destination country. The destination server and VoIP-PSTN Gateway transfer the call to its final destination. The phone number on the last leg of the call routing should be spoofed with the original number. From a scope perspective we are looking at two to three end points in the UK. If you are interested in such a project please let me know so we can setup a call and discuss the details and the actual cost.

    Summary: We need a solution to allow our call center agents to click on a button in a PHP page which then causes the Asterisk server to barge into the current queue call of the agent and play back a recorded message. After the playback is complete, Asterisk needs to 'listen' for the external caller to press '1' and must ignore any key presses by the queue agent.More detail...1) Patient calls in and speaks with a queue agent in our call center.2) When the agent reaches the right point in the call using our web-based script system, the agent presses a button on the web page.3) The press of the button sends a command to the Asterisk server to barge the agent's existing call and playback a recorded message--audible to both agent and the patient. We will need help understanding how to pass the necessary variables (1) agent number or unique call id, and (2) patient ID number) from the PHP-based web page on a web server to the Asterisk server.4) When playback is completed, Asterisk continues to 'listen' on the call until the patient presses '1' or the call is ended by either the patient or the agent. 5) Asterisk must ignore DTMF codes pressed by agent on their local phone--and accept only touch tones from the patient.6) Once the '1' is detected from the caller, Asterisk must play one more pre-recorded sound clip and add an entry to a MySQL table noting the acceptance, the agent number, the patient ID (provided earlier via the remote call from the web page), and the exact time and date of acceptance.7) Asterisk does not need to do anything further on the call. The agent or patient continue talking as needed until one of them hangs up.IDEALLY: This process would work regardless of who initiated the call (whether we answer the patient's call or if we call the patient)-- but for the purpose of this project, it is inbound calls which we need to make this work for.

    I have a main office with approximately 250 extensions on a single Elastix server, plus 4 remote sites, each with its own Elastix server and from 2 to 10 extensions. Although the system 'works', we want to move to a more fault-tolerant system which 'finds' extensions in the system rather than requiring statically defined outbound routes, etc. We would also like to switch to the FreePBX distro instead of the Elastix distro.So, there are two primary parts to this project:Part I: Main OfficeIn the main office, we want to utilize two servers (either in a master-slave or master-master configuration) to provide a high-availability solution with less than 20 seconds of downtime in the event a server fails. We have approximately 25 queues at present with a call volume of approximately 2,000 calls per day and 110,000 minutes of voice time per month. All voice traffic is routed either to another company PBX via SIP over the Internet or via SIP to an ITSP provider. Part II: Remote OfficesFor our remote offices, we are looking to switch from Elastix distro to FreePBX distro and to introduce automatic routing of calls, based on 'extension presence' on remote PBX servers. All voice traffic is routed either to another company PBX via SIP over the Internet or via SIP to an ITSP provider.Deliverables:For awarding this project, we are looking first for a proposal of how to structure our system (which technologies you propose that we use)Then once the project is awarded, we are looking for a detailed HOWTO on implementation, along with support for initial deployment. We would also want the project winner to be available for future paid support, as needed.I fully expect that more information is needed for being able to bid, so please ask questions and I will reply with project clarifications.
