Hi All, I would ideally like PJSUA to use the public ipaddress of the local machine. I am using microsip. When I make a call to another party it always shows in the call window that it is calling the private ip address of the other party. I would like to see it using the public ip address of the remote party, so we can use port forwarding to complete the call. I thought, in the code, this was sufficient ? acc_cfg_local.id = pj_str(StrToPj(returnURI)); acc_cfg_local.force_contact = pj_str(StrToPj(returnURI)); Where the return URI takes the form <sip:user@[local public ip address]:[port]> Thanks in advance.
