[OpenSIPS-Users] How to route calls between SIP domains

[Jeffrey Zhao]

Dear Sir/Madam
We are using multiple SIP domains in one OpenSIPS instance, for example
1001 at aaa.com
2001 at bbb.com
Both extensions register with the same OpenSIPS, if 1001 at aaa.com want to call 2001 at bbb.com, the SIP URI the phone sent out will be 2001 at aaa.com, how to configure in confit file to translate to 2001 at bbb.com?
Thanks.
