There seems to be a bug since 2-3 days with this option.
Earlier if the sip extension was busy - the call would go to voicemail.
But now even with the option "FORWARD ON BUSY" Not Setup to any number,
If the SIP is busy the call is being forwarded to extension setup undre "Forward on unavaliable"
And worst is that the On hold music stops playing - and my trnasfer is to a mobile number and the caller starts hearing the local mobile phone ring after the on hold music stops (This happens when the sip xtension is busy) - however no forward has been setup on busy.
Please help - Let me know if the above doesnt make sense / any other info is needed
