## FreePBX tftp server

This is an advanced tftp server that automatically generates config files for cisco sip phones.

## How it works

FreePBX server syncs with FreePBX. Binding users to phones is carried out through the fax field in the user properties from FreePBX. The tftp server receives a request for a file of the form `SEP<MAC>.cfg.xml`, makes a request to the FreePBX database, generates a config and sends it to the phone. All other files are taken from provided folder as-is.

## Requirements:

* [go >= 1.16](https://golang.org)
* [FreePBX >= 15](https://www.freepbx.org)

## Flags:

```bash
Usage of ./freepbx-tftp-server:
  -freepbx_db string
    	Set freepbx db connection string (default "asterisk:password@tcp(127.0.0.1)/asterisk")
  -sep_template_file string
    	Set path to sep template file (default "./sep-cisco.cnf.xml.tpl")
  -workdir string
    	Set working directory (default "/tftpboot")
```

flags may be set via ENV variables by capitalizing flag name, e.g. 

```bash
SEP_TEMPLATE_FILE=/tftpboot/sep-cisco.cnf.xml.tpl
```
