Hello

I've got an easy configuration for SER and all I want it to do is to forward to a PSTN GW in 10.140.0.4 all the calls that are not 331xxx. The inside calls work alright, and I can also make calls to PSTN phones, the problem is that SER keeps sending INVITEs even after the caller has hanged up, or even after a conversation, so the callee rings (but noone is calling, and if you answer there's no communication). I enclose my ser.cfg, please help!! Thank you,

Llanos
