Using PJSip for an extension we have it set to allow for 3 contacts. I provisioned Yealink with endpoint manager. When I go to the extension to enter the contact I select the brand, but the model does not show up.
We have several brands provisioned. None of the models appear if we choose the various brands.
I think I solved my problem. Apparently you need to provision the SIP device by adding the MAC first. Doing that provisioned the rest of the related fields. Whodathunk
