UC520 8.6 bind commands breaking MWI

As some of you may know, software pack UC520 8.6 adds 2 bind lines in the config -

voice service voip

sip

  bind media source-interface Vlan100

  bind control source-interface Vlan100

These above lines are required to register SIP based phones such as 9971 or Iphones.   Unfortunately having these lines in the config also causes MWI to stop working. 

What is a standard setup/config to have both SIP phones registered and MWI working simultaneous?

Thanks in advance

the issue will be next CCA 3.2.2,

for now, you can just remove these 2 lines, this is for remote teleworker access only, and 9971 not support remote teleworker with UC500. other thank this everything will be fine include MWI.

bind media source-interface Vlan100

Bongsu,

Are you saying SIP phones such as 9971 do not depend on those 2 lines for it to work?  So I can remove the two bind lines and get a 9971 or Iphone working?
