I just installed the last version of Freepbx and I received the following request. The client would like to have the camp on function with pjsip extensions. Basically when someone try to call an extension that is currently busy, they would like to use a feature code to book the call … and be called back as soon the desired extension is available again. Is there anything compatible with Freepbx and pjsip? I tried to enable Camp on function in freepbx but it seems discontinued and not compatible with pjsip.
I am not aware of a work around. We get a few requests a year for this feature, almost always from European users. The concept of a camp-on feature never really caught on in North America, so there is very small demand here for it.
