Hi John and Steffen,

 

is this dial out issue still present? Or has their been a way to configure the Trio?

 

Out of the box, the Trio still does not allow PSTN dial-out when signed in with Office365 accounts enabled for PSTN conferencing.

 

Any update would be appreciated.

resurfacing this article 3 years later since I came across it having the same problem.  I want to share my workaround so other people know how to fix this.  You have two options: Teams profile but no PSTN calling, or PSTN calling (SIP Generic profile) but no Teams app.


For the Polycom Trio 8800, even though it has a "Teams" profile and Polycom considers it to be Teams Certified, it's not.  The Teams profile functionality will work as a Teams user with most Teams functionality, except you will NOT be able to make outgoing PSTN calls and you will not have a dial pad.  The only way to make this possible is to reformat the phone with a GENERIC profile (not Teams) and follow Microsoft's documentation for setting up a common area SIP phone.  It takes away the Teams app and features with it, but it turns the Trio into a standard phone that allows incoming and outgoing PSTN calls. https://docs.microsoft.com/en-us/microsoftteams/sip-gateway-configure#provision-and-enroll-sip-devic...
