Terminating the dialog usage is the default behavior in case of error response. > I don't want it to terminate the subscription > simply because of a 500 Glare condition. Can I control this? Currently, no. However, if you look at nua_stack.c around line 2714, it calls sip_response_terminates_dialog(). Based on the graceful, nua then decides whether to terminate the dialog usage (by sending NOTIFY with S-S: t terminated). Now s_r_t_d() can either set graceful to false, to true or leave it as is, depending on error code. In case of 500, it is left as is, to the initialized value, 1. You can try to initialize graceful as 0. There probably should be a tag controlling the default value. -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
