There is a lengthy debate about other issues with the business version of the Superhub going on in this thread on the official VM community forum:

Apart from mention of the VOIP issue there is a definite problem with running email server traffic through SH. VM acknowledge the problem and have a workaround but several claim that does not work.
VM staff do not respond to business service matters on that forum (there is not one for business users). If anyone with knowledge of the business modem service would like to comment here it would be appreciated as we have having one installed tomorrow.
