Developer Documentation - Introduction


In order to be able to better integrate our phone system into the our customers IT environment, it is possible to access a pascom phone system using a number of interfaces.

System Architecture

In order to be able to choose the most appropriate method of integration, you must first have knowledge of the acomplete pascom architecture:

Available Interfaces

One can see from the diagram above that there are currently 5 possible interfaces for pascom. Depending on the application, you should choose the best option for your project. The following table helps you to differentiate between the possibilities:

Interface Explanation Focus Benefits Negatives
SSH Access via putty/ssh/scp/Batchscripts Automation on Operating System level. Start/Ending of Services low level File operations etc. Direct access to all Operating system functions and services
AMI Asterisk Manager Interface Direct Control of Asterisk Functions without additional abstraction layers Simpler entry, Clear Text Protocol on the TCP socket Depending on requirements, steep learning and cost curves.
HTTP-UI Remote control of UI/Browser Simple Operations Management. Very easy to use We cannot guarantee compatibility between versions, scripts on this level are fragile. Generally, as a result you should refrain from using this interface.
REST HTTP access to many high level system aspects Master Data and Live State read outs. Options for; User login/out, Roaming, Queue Agents Operations, Coupling on system to system level. Simple entry thanks to interactive documentation One-Way Protocol, no event control possible.
XMPP Real time access in the Telephony System Complete actions for individual users, react to telephony events. Enables coupling on system to system or user to user levels. Highest Abstraction level. All Data and events are based on pascom objects. Fully Documented. Entry is only possible with a suitable Framework in the preferred programming language. Steep learning curve and lengthy and wordy protocols.
