Using Asterisk 1.8.6.0 on the FreePBX distro
The phone is not set for DND. However, some calls go through and the phone rings normally. Other times it doesn’t ring at all with the the user getting a busy message voicemail.
“sip show peers” comes up around 70-100ms.
Even when the phones gives busy message status is always OK and registered.
Is there any way to troubleshoot this phone and see what’s going on?
