You should not need four invoices to know what a phone call cost
A short spoken explanation of how callex bundles telephony, transcription, language models, and voice into one monthly bill for trade businesses.
When an HVAC shop tries to set up an AI phone agent, it usually means four separate vendors. You pay a telephony provider for the line, a transcription service for speech to text, another company for the language model, and a fourth for the voice. At the end of the month, you are adding up four invoices just to see what a five minute call about a leaking water heater actually cost. We built callex so you get one bill for everything. Starter is ninety-nine dollars a month with one thousand minutes included on your own business number. Telephony, transcription, the model, and the voice are all covered. Go to callexapp.com, type in your website, and let your new agent call you.
