Separate SIP trunk for agents

Hi,
Is it possible to configure extensions.conf / sip.conf / iax.conf so that each agent was assigned a separate sip provider account (only outband)?
Agents use softphones (IAX2). Autodialer is on.
Is it possible to set an additional pool sip provider accounts for autodialer?
