PS : you should remove lines
loadmodule "/usr/local/lib/ser/modules/pdt.so"
modparam("pdt", "db_url", "sql://pdt:pdt_password at localhost/pdt") modparam("pdt", "db_table", "domains") modparam("pdt", "prefix", "2") modparam("pdt", "terminator",0) #modparam("pdt", "start_range", 200) #modparam("pdt", "hsize_2pow", 2)
prefix2domain();
This lines serve to configure pdt module wich can convert a sip adresse with prefix in a domain name (i.e. 23330456@domain.com -> 456@other_domain.com)
