Outbound routes rules?

I have two asterisk servers.
Server A : I have sip accounts : 1101,1102…
Server B : I have sip accounts : 1201,1202…
Server A : i want to press 201 to call to account 1201 of server B.
How outbound routes do i config ??

Connect two server through IAX and configure the contexts accordingly

i connected two server through SIP and config outbound routes rules ??

Asterisk does not know anything about inbound/outbound rules/routes. This is a FreePBX nomenclature. Asterisk understands extensions and contexts. The question should be asked in your distro forum.
