[OpenSER-Users] OpenSER - a slow starter?

[Bogdan-Andrei Iancu]

Hi,

by default openser tries to do reverse DNS lookup on the IPs you put in 
"listen" to learn all the aliases (DNS records pointing to this IP).

To disable this, set the global parameter:
    auto_alias=no

Let me know if this makes a difference or not.

Regards,
Bogdan
