[OpenSER-Users] serialize_branches seems to be not working

Hi to all, i'm using openser 1.2.2 no tls and i use exec_dset to get list of gateways in destination set to be serialized. After execution of exec_dset i get in output: sip:123456@10.10.10.1:5062;q=0.2 sip:123456@10.10.10.10:5060;q=0.1 $ds become : Contact: sip:123456@10.10.10.1:5062;q=0.2, sip:123456@10.10.10.10:5060;q=0.1 RURI become: sip:123456@10.10.10.1:5062;q=0.2 $bR become: sip:123456@10.10.10.10:5060;q=0.1 All seems to be fine but when i run serialize_branches() i get: DEBUG:serialize_branches: nothing to do - all same q! Any ideas on what i'm missing? May be something in the output of exec_dset?? I'm using the \n between lines in my custom LCR scripts to get gateways from DB. Thanks, Bye, Marcello
