Can't create new phone call if company is null

Hello,

It seems I can't create new phone call and link to with a contact if contact's company isn't set.Company field is optional for PhoneCall, as it is described in Netsuite documentation. I tried the situation when both contact and company are present and both are absent, everything works. Could anybody please tell me if it is my fault or not?

Request:
