How to specify source ip

[michaelbrucelin]

I have been using the sip-option command in my program for a long time. Recently, I encountered a problem. The server has multiple network cards and multiple public IPs configured. I want to use the specified public IP as the source IP to execute sip-option. How can I do this?

Public ip1 is the default route, and the A record of hostname is public ip1. Public ip2 is currently just configured. I want to do policy routing later, but it is currently just configured and nothing has been done. However, as long as public ip2 exists, sip-option will use public ip2 as the source ip. How can this be solved?
