Peer names have to be distinct, this is just a fundamental design 
element of chan_sip. What a lot of people end up doing is instead of 
treating peers as people they treat them as devices. The peer name 
becomes the MAC address of the device they have been assigned.

Since peer names are not the same as extensions though you can certainly 
have multiple john extensions on different domains. You need to create 
different contexts which route them accordingly and then map the domains 
to the contexts in sip.conf

Take a gander at sip.conf.sample - specifically the SIP DOMAIN SUPPORT 
section and you'll see what I mean.

Cheers,
