[asterisk-users] No ringback even though progressinband=yes is set

[Douglas Mortensen]

I have inbound calls going directly to a ring group. When callers call in, they (the callers) hear complete silence even though the phones that are part of the ring group ARE ringing properly. Employees can answer the calls when their phones ring, and everything works fine.

The problem is simply that the external caller never hears any ringing. Even if the SIP phones in the ring group ring for 5 rings, it is total silence even though there is ringing going on inside of the office.

I'm pretty sure it is a ringback issue.

I'm going to try to turn on SIP debugging & see what I can figure out that way. I do appreciate your help.

If you are referring to a ringback tone when they first dial your system, meaning that they immediately hear your IVR when they dial your PBX's number, it's because that's how it's supposed to work. Unless you tell your PBX to use the Ringing() app and wait for a period of time, Asterisk normally picks up at the beginning of the IVR (since the first thing you have to do to send audio via Background or Playback is issue the command Answer() to start sending actual audio. (Note: The Ringing app just signals RINGING to the remote party)
