Do you have:

sip-ua
mwi-server ipv4:x.x.x.x unsolicited

Brandon

[Vishal Parekh]

Yes, I do have this command under my CME;

sip-ua

mwi server ipv4:10.105.61.2 unsolicited

I have followed few documents and configured unsolicited configuration on both side - CME & CUE but did not worked out for me. 

what are the traces level and how I should collect to check the errors ?

Regards,

Vishal
