In diploma we were studying various options of capacity upgrade of a
telephone system in a healthcare organization in Novo mesto.
In the introduction we presented the needs of the healthcare organization and in
the next chapter we looked over the possible scenarios for upgrading the telephone
system and we as well picked three solutions. Than we presented the three studies,
first possibility was an upgrade of current system, second solution was a commercial
system 3CX and the third solution was open source system Asterisk. For closure we
justified our pick of the solution based on the data that was available to us.
