[Users] looping problem

Thu May 4 11:29:43 CEST 2006

Here is the alias and listen statements.

listen=10.200.0.228:5060                # INSERT YOUR IP ADDRESS HERE
listen=10.200.0.228:6060                # INSERT YOUR IP ADDRESS HERE
listen=210.14.7.5:5060         # INSERT YOUR IP ADDRESS HERE
listen=210.14.7.5:6060         # INSERT YOUR IP ADDRESS HERE
port=5060
children=16

dns=no
rev_dns=no
alias=o6.ol.com
alias=10.200.0.228
alias=210.14.7.5

In the server, there are 2 interfaces (internal and external).  I put
both of them in the alias and listen statement.  Anything wrong here?

Why openSER fail to recognize the request (CANCEL) as targeted to
itself?
How do you solve and prevent this problem?  As the performance of the
server will degrade when this loop happen.  It must be a way to
prevent it otherwise users connected to the system will be affected.
reduce the time-out parameter?
reduce the number of hops?

Thanks for help!
