40s Call Delay before call is initiated on zoiper using UCM 6204


For some reason there is a 40second delay from pressing the send key before the dialled number starts ringing,

Outbound dial plan is ok, Please any insight.

Thanks in advance.



How is Zoiper connecting - Wi-Fi or cellular.

Take a network capture at the UCM while conducting a call so we can see what is actually happening. Start the capture before dialing and end after.

Is there a difference in timing when dialing voicemail?


… also, have you tried recording only locally if it’s the same delay?
