TopTel Türkiye is the authorized distributor of Avaya in Türkiye. We deliver the Avaya IP Office platform together with our partners, backed by solution design, product training and QPS engineering support.

What is Avaya IP Office?
Avaya IP Office is a unified communications (UC) platform built for small and midsize businesses, bringing voice, voicemail, mobility and contact center capabilities together in a single system. Its modular design lets it grow from a single-office business to a multi-site organization. According to Avaya's R12.3 documentation, IP Office Server Edition scales to 150 sites in a multi-site network, and an IP Office Select configuration supports up to 3,000 users.
IP Office is a hybrid system that supports TDM and IP telephony at the same time. Existing analog and digital lines can be kept while you migrate step by step to SIP trunks and IP phones. Deployment options range from compact hardware appliances to virtualized software running in a data center.
