<div dir="ltr"><div><div><div>Hi all,<br><br></div>I have a user with an old Mitel PBX connected to a couple of SPA112's. The user is reporting that their phones ring several times a day and when they answer the "call," all they hear is dial tone or busy signal.<br>
<br></div>Their PBX guy says that the SPA112's aren't providing line supervision and the PBX requires it.<br><br></div>Does anyone know how to fix this? I'd also like to fix it from a provisioning file, if possible.<br>
<br>Thank you!<br><br>Mike.<br></div>
