+1 for this! We were on the board about switching to Close since HubSpot is missing this but ended up using an integration with HeyMarket which works okay but it would be better if it was all native. Makes sense since we already have the HubSpot phone number. Somewhat akwards calling and texting from two different numbers.
Totally agree with everything else said here. It would be so nice to be able to send and receive calls and texts from the same phone number (my HubSpot one)
