Hi ALL; 


I have been trying to work with ser+mediaproxy but I have one way audio problem

I have the following network:

UA (private ip)--------------------unix nat router------------------(public-ip)ser+mediaproxy-------------------------------UA(public ip)


1) I donot use any db for domain.so , what is it?

2) I run it with /etc/init.d/mediaproxy suuceccfully. how do you run it???????????  

3) It appears ser canot find mediaproxy while I can run it successfully.I got the following errors :



0(5982) DBT:dbt_load_file: request for table [domain]
 0(5982) DBT:dbt_load_file: db is [/usr/local/etc/ser/]
 0(5982) DBT:dbt_load_file: loading file [/usr/local/etc/ser/]
 0(5982) DTB:dbt_db_get_table: domain
