Aircall is the phone system: calls, voicemails, missed calls and the tags agents add while on the line. HubSpot holds the pipeline: contacts, companies, deals and the emails and sequences around them. A prospect calls, the call lives in Aircall against a number, and the deal in HubSpot shows no activity for a week, because nobody logged it.
Liaison reads Aircall and HubSpot together, matches each call to a contact and a deal, and tells you which leads called and were not called back, which deals have gone quiet, and what was said on the calls that matter.
On Professional we connect your tools, bring your data in and set up the first rules with you. Anything that moves money waits for your yes.

Where Aircall provides a transcript, yes. It tells you when it only has the audio.
