Development of Asterisk OpenStandards Software

Developed in 1999, the OpenSource software is the creation of Mark Spencer. Operated with Linux, the software consists of four core modules. The PBX core switching model for in- and outbound calls plus the implementation of the differing technologies from VoIP to hardware. Voice channels and various applications are managed by the Schedule and I/O Manager. Phone ringing or call forwarding functions are controlled using the Application Manager Module.

In addition, Asterisk controls all protocols such as ISDN, SIP, GSM or IACX2. The OpenSource software offers a massive range of functions accross all protocols and is therefore a highly flexible future proof solution for nearly every telephony infrastructure. A particular strength of Asterisk systems is that VoIP endpoints can be connected without requiring specialised hardware. pascom’s specifically developed admininstrations User Interface, which is based on Asterisk, leaves nothing to be desired.

Lars Hoeger, IT Director
When we make decisions regarding new systems, we want to make sure that we have both reins firmly in our hands. Therefore, it is essential to implement systems which adhere to OpenStandards, allowing us to seamlessly connect and integrate these into our existing systems. In addition, we require reliable suppliers, who are ready to customise their solutions to our requirements, which is why we chose pascom who offer exactly this service and more.

Kassandra Martin, Deputy Director & Reception Manager
We chose pascom as our telephony solution in part due to the scalability, flexibility and ease of deployment. In addition, the pascom platform functions perfectly with our digital guest directories in our rooms whilst offering the largest range of features at easily the most cost effective price compared to alternative solutions. A further deciding factor was the wide choice of compatible hardware that choosing pascom afforded us.

Markus Gerlitzki, Managing Director
My team and I pride ourselves on the level of excellent care we provide our guests. However, it can be distracting when the phone is always ringing and we constantly answer the same questions. Thanks to the pascom phone system, we have been able to set up an automated attendant self-service hotline which allows guests to quickly get answers and if required callers can be quickly and efficiently routed to an employee. The system greatly improves customer service with around-the-clock answers around opening times and courses and therefore reduces the strain on employees, ensuring we are free to cater to the needs of our on-site guests.
