Hi All, it's me again! I am trying to set up a remote location with 6 Yealink T19P E2 everything went good with the auto provisioning however when the extensions receive inbound calls, they have no sound. the caller can hear perfectly but the recipient cannot hear anything. Outbound calls work fine. It's not possible to use SBC and I have used the standard provisioning template. Running v15.5 and all firmware updated to 184.108.40.206. Any ideas? Thanks!
