Take a look at outbound_proxy for pjsip
https://wiki.asterisk.org/wiki/display/AST/PJSIP+with+Proxies

With chan_sip you could do this dynamically from the dialplan:
; A new feature for 1.8 allows one to specify a host or IP address to use
; when routing the call. This is typically used in tandem with func_srv if
; multiple methods of reaching the same domain exist. The host or IP address
; is specified after the third slash in the dialstring. Examples:
;
; SIP/devicename/extension/IPorHost
; SIP/username at domain//IPorHost
