[Serusers] using ser on localhost

[Cory Zue]

Hi,

I'm trying to write a sip client and I am testing it with ser, but I have 
been running into problems.  I'm trying to test it on one machine, by 
setting up two clients on two different local ip addresses, and having them 
talk through ser, which is on a third ip address.  I think that ser is 
listening on 127.0.0.1, so I tried to set up my clients on 127.0.0.2, and 
127.0.0.3, but when I try to bind them to port 5060, it says that it is 
already in use (I'm assuming by ser).   Does ser bind to all local ip 
addresses at port 5060?  Or is there a way around this?

thanks,
Cory
