Depending in how your are connected to the PSTN, you may have to generate the ringing tone yourself. SIP generally will send a "ringing" message, but it's up to the client to provide the tone. Sometimes, I'll get one from the remote side, but that's after the media path is established. The PJSUA library has a tone generator you can use to provide this as well as other tones, e.g. dial tone, DTMF, etc. Norman Franke ASD, Inc.
