No, different peer names
exten 400, s, DIAL(SIP/400&SIP/400b&SIP/400c&...)

But all stored in the HINT channel variable, not in the dial plan.

Seems like you are creating a quick fix... ;-)
Well, with my solution, it will be part of a HINT that is shared by
all devices registering to the same peer...
