[Serusers] Problems with SER pdt module

I use ser 0.8.14 with pdt module in order to call other people on other domain. a sample of my ser.cfg: loadmodule "/usr/local/lib/ser/modules/pdt.so" modparam("pdt", "db_url", "sql://ser:ser_password@localhost/pdt") modparam("pdt", "db_table", "domains") modparam("pdt", "prefix", "2") modparam("pdt", "terminator",0) route { ..... loose_route(); prefix2domain(); record_route(); ....... } I entered in DB the code and domain matching. code = 333 domain[333]=fwd.pulver.com (0 is the terminator digit by default) When I use Xten client (SIP softphone) and I call a user at fwd.pulver.com from mydomain.com : 23330XXXXX(a)fwd.pulver.com fwd.pulver.com tells me Too Many Hops ? Where is the problem ? fwd.pulver.com ? Or my SER ? My SER works perfectly with all users registered at it. Thanks you
