example tables:

mysql> select * from gw;

2 rows in set (0.01 sec)

mysql> select * from lcr;

2 rows in set (0.00 sec)

mysql> select * from gw_grp;

Ok this should set you up to route calls from an incoming pstn and proxy them to feature servers based on prefix (phone number)

the ip address of desitnation server needs to be this: reverse ip address, convert to binary, then convert to a decimal number

so 19005552222 will be send to sip1 and 19005553333 will be sent to sip2

make sure you are using a stable version of SER!!!!
