VoIP Phone app that integrates with Shopify customers info (orders/inbox)

[dagoodretail]

Basically had a headache trying to use Aircall, but support is dead, so I thought I ask around.

Need a VoIP Phone app that integrates with Shopify customers info (orders/inbox).

Usability:

to see customer name and order details when he calls

being able to pull up relevant info in real time

ideally also integrates with mail system (gmail) so you see the whole picture of interactions with a customer.

Haven't tested yet a Swarm app, only has 1 review now... may test it later. Maybe someone already has an app that I can't find? Anyone really uses Aircall?
