We have been using a third party whitelabel provider for IoS and Android softphones. They work ok at best. Have a few good clients, that really use the softphone, that complain it does not maintain call or registration status consistently.
Does Sangoma connect work reliably?
Does Sangoma connect implement PUSH so “sleeping” phone apps wake up and take the call?
Do you recommend Sangoma Connect?
Sangoma Connect is based on the acrobits SDK (Groundwire), which many consider to be the best mobile SIP platform going at the moment. Don’t take my word for it, there is a free 2 user trial you can use to try it out.
