    We currently operate OpenSER 1.2 as a Media Proxy and SIP Registration server back-ended to Asterisk 1.4. We have PERL scripts operate a HostedPBX platform we have written ourselves within Asterisk and a web interface based on PHP and MySQL.We require assistance to set up a new server which will need to operate on the EC2 platform of AWS Sydney. We would like to use CentOS 6.4 as the base operating system. We would like to use SIP-Router project to replace OpenSER 1.2 and also upgrade to Asterisk 11.x LTS as it is supported for another few years (later to upgrade to 13.x probably about 9 months after initial release to ensure stability).We need to ensure the following Asterisk functions work through the SIP-Router Proxy:* BLF Lights for calls made, transferred and in progress* Call Group Pickup* SIP Registration on SIP-Router itself (not on Asterisk)We will need to make sure that our MySQL Database works with the new Asterisk 11.x and configs will need to be adjusted to make this work.We currently are using PHP5.1.6 and MySQL5.0.95 (but would like to upgrade both to latest stable versions during this process).We will put up a copy of our MySQL Data, PHP Pages and PERL code onto the new server on AWS Sydney as well as the old OpenSER and Asterisk 1.2 config files for your reference. We will need to ensure the new system works with all the functionality of the old system as well as making sure the above (BLF and Call Group Pickup) works properly too as we currently have issues with it on our old system.No changes to our PHP pages should be needed and our existing MySQL database structure should work for everything. SIP Users details are stored in an openser database separate to the Asterisk database.Please provide a cost for this project as well as a timeline for completion. And if you have any questions, make sure you ask me to clarify everything for yourself.

    We are looking to migrate our existing on-premise PBX setup (Elastix 2.4.0 CentOS x64) and all of it"s settings to the Amazon AWS EC2 (free tier) cloud platform.What we have:- A live, fully functioning, on-premise PBX running Elastix v2.4.0 with all extensions, IVR, MoH, Queues, and settings perfectly setup how we like.- An active, unused Amazon AWS account with no currently installed instances.- Intermediate knowledge of AWS and PBX to answer questions or collaborate with the migration.What we need:- A fresh AMI install of Elastix v2.4.0 onto EC2 (or v3.0 if you"re sure we can import existing settings from v2.4.0)- All settings/extensions/IVR/recordings migrated from our current on-premise PBX running v2.4.0.- Firewall rules setup and locked down so there is only access to SSH or HTTP from our specified IP addresses.- All external logins/credentials removed so the system is thoroughly secured.- A basic 15 minute Q&A after everything is tested so we can be sure everything is 100% done.
