Minimum php version issue #1
Description
Fatal error: Call to undefined function json_last_error() in /library/TelApi/Schemas.php on line 66
In the readme it says php 5.2+ is recommended but json_last_error() is only in 5.3+ so the library wont work at all. Im running 5.2.17

Perhaps doing a phpversion() check would helpful to notify developers that they need to upgrade in order for the library to work on their machine.
