Hello, dear colleagues.<br><br>I have a problem with outgoing SIP calls to ITSP. ITSP doesn't send to my CUCME ringing (180) packet at all, so, during the outgoing calls to ITSP from CUCME internal extension I've heard only silence before I received OK (200) from ITSP and started to listen to the remote party RTP.<br>
<br>So, signaling seems like: CUCME > INVITE > ITSP; then CUCME < Trying (100) < ITSP; then silent without ringback and then CUCME < OK (200) < ITSP.<br><br>Is it possible to configure CUCME to play "ringing" tones before/without receiving ringing (180) from ITSP during outgoing calls?<br>
<br>Thank you for your reply in advance.<br>
