We are currently in the process of attempting to migrate away from physical desk phones to softphones. However, our inbound customer service staff has a frequent use-case that has been difficult to achieve.
CS Agent receives call from customer
CS Agent determines that third party provider needs to be involved.
CS Agent conferences in third party provider
Customer, third party provider, and CS Agent all discuss the issue
Third party provider and customer need to continue the call directly, but the CS agent needs to drop to handle other calls
On our Yealink desk phones, we are able to use “transfer on conference hangup” to achieve this behavior. We have not, however, been able to find a softphone that has the same behavior.
