I am looking for a very talented VOIP engineer who has significant experience building open source VOIP platforms with high availability and large throughput.
You have worked with Asterisk, FreeSwitch, and the various OpenSER forks.
You have built VOIP environments that span multiple servers.
You are familiar with complex routing with multiple trunks and multiple call groups.
You can tie all this to a database such as MySQL or PostgreSQL for configuration and billing.
Please let me know how many hours you are available for this project and how soon you can start.
