ez buy thailand client

“Ezbuy Thailand decided to go with Infinity IT’s CallControl VoIP solution because they are good at what they do, and are very hands-on in their approach. We managed to serve all incoming calls from our customers, with few hassles – all within 2 weeks after successful setup”

"CallControl connects our three Thailand locations, and our staff in the field, with our international customers, partners & suppliers, at a great quality, within one simple to use telephony system. Connecting callers quickly & reliably with the right staff, service & information, is extremely important for us, regardless of the staff’s current whereabouts. CallControl reinforces our customer responsiveness and brand image and is an essential component of our client success strategy"

"Our challenge: without a physical office location and affiliated landline number, we could not get BOI approval. Without BOI approval we could not the get the keys to our manufacturing facility, to install and answer the phone. CallControl allowed us to have a fully operational phone system and local DID number, to use from our hotel rooms. This expedited the BOI approval and opening of our manufacturing site and office in Amata City. CallControl also connects to our Australian head office, so we don’t pay a cent when we call home."


"As an international start-up in Bangkok, we required a fully functional but affordable telephone system, with modern call management features and a great deal of flexibility. We also needed a highly scalable system that can grow with us, at a moment’s notice. We found CallControl Hosted VoIP to be the perfect fit for our requirements, without the need to make heavy investments. And it’s great to know that it simply works, without any fine-tuning or trouble-shooting"
