Hello, I have a Polycom 301 phone that used to work perfectly. I have updated the bootrom to 3.2.2 and SIP version 2.0.1. Upon testing, I realized that MOH does not kick in when I hit the Hold button (or use the softkey) on the 301. The call is put on hold on the phone (mic. is muted), but it appears as if Asterisk is unaware that the call has been put on hold. (Pressing the Hold button does generate SIP traffic to Asterisk, but the MusiconHold command is never executed)
This used to work fine. It also works fine with an xlite softphone I use.
Any ideas if this is a problem with the phone’s software or an asterisk issue?
