Hi all, I am wondering if chan_oh323 or chan_h323 supports NAT traversal the following setup: H323 phone -----> Asterisk -------> NAT router -----> H323 gateway -----> PSTN I am trying to register a H323 gateway through a NAT to Asterisk for outgoing calls to PSTN. How can I achieve the above? Please help and advise. Many Thanks. Newbie
