Thank you for the suggestion Obi Guru.
I also went through the OBI configurations for SP1 and I think these are the setting/fields that are filled up by the config wizard for Broadvoice. I'm enclosing this so that if someone else wants to manually configure either SP1 or SP2 for Broadvoice, they can manually do it.
ITSP Profile A --> General
DigitMap : Default unchecked ((1xxxxxxxxxx|<1YYY>[2-9]xxxxxx|011xx.|xx.) (Replace YYY with the your phone number AREA Code)
ITSP Profile A --> SIP
ProxyServer :
sip.broadvoice.com (Default unchecked)
ProxyServerPort : 5060 (Defualt unchecked)
OutboundProxy : leave the value blank (Default unchecked)

Voice Services --> SP1 Service
