I have a problem with ring-back tones while making blind transfer on sip extension.
I have SIP extension A registered with ekiga softphone. This extension calls other extension B that answers the call and makes blind transfer to extension C. Once transfer is done, A hears silence until C picks up.
I tried to send “Ringing 180” message to sip client of A to force it play ring-back, but it did not help.
Can any one help me with this?
