Hi, the problem is that gnugk 2.2.1 in your codec has commented q933´s message send. When we uncomment this part and re-compile the ring-back work fine. Best regards.

The called endpoint sends an Altering signal and the calling endpoint plays a locally-generated ringing tone to the caller. 2. The called endpoint sends a Progress signal and then sends an audible ringing signal in the RTP stream. This may be generated locally, or passed on from the PSTN, destination PBX, etc. This type of ringback is usually more desirable, because there are often audio announcements (changed number, cell-phone out of range) given before Connect. Even if there are no announcements, it is useful to hear ringing appropriate for the country you are calling. gnugk never creates either kind of ringing; it should just pass on whatever signaling it receives from the called end. The most common cause of not hearing ringing is that the calling endpoint (or its GK) is behind a NAT or stateful firewall. The incoming audio is not passed on to the caller, until some RTP packets have been sent out by the caller. However, the calling endpoint will normally send audio only after Connect has been received. You should configure suitable port forwarding to fix this. Some endpoints won't play local ringing if logical channels have been set up, even if there is no audio actually present. Some endpoints won't negotiate logical channels until Connect, even if Progress has been received. In many cases, turning Fast Start on (or off), or changing an endpoint setting related to Alerting, will help. If you still have trouble, use Ethereal to see if media has been negotiated, if RTP packets are coming in, and if there is ringing tone actually present. If you ask for more help, tell what kind of endpoints are used, where NATs or firewalls are present, if gatekeepers have multiple interfaces, what GK routing or proxying is involved, etc. --Stewart -----Original Message----- From: Gustavo Espeche [mailto:gespeche@xxxxxxxxxx] Sent: Friday, February 11, 2005 6:56 AM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: ring-back Hi anybody knows for what the gnu-gk doesn't send ring-back when it is connecting to other gk. Endpoint-->gkcisco-->gnugk-->othergk. Gnugk is register as gw in gkcisco. When I do a call I can't hear the ringing in my endpoint. Do I need configure something in my gnugk? When I connect directly the endpoint to gnugk is work fine? Endpoint-->gkcisco-->gnugk-->othergk (I don't hear ringing) Endpoint -->gnugk-->othergk (I hear the ringing) Thanks.
