yes, Asterisk does support multiple registry entries...
if it didn't ... it would be just a crippled sip endpoint

lets say more ... Asterisk can do whatever you want it to do (within

Rather than trying to configure/code/etc around the problem with the ITSP, use an ITSP that does things correctly. There are many people here on asterisk-users that can recommend a proper ITSP. If you want pure business response, head over to asterisk-biz and ask there.
