а точнее, кто такой p->owner
не знаю. для application/dtmf-relay такая проверка уже была.
if (!strcasecmp(c, "application/dtmf-relay") ||
!strcasecmp(c, "application/vnd.nortelnetworks.digits") ||
!strcasecmp(c, "application/dtmf")) {
unsigned int duration = 0;
if (!p->owner) { /* not a PBX call */
transmit_response(p, "481 Call leg/transaction does not exist", req);
sip_scheddestroy(p, DEFAULT_TRANS_TIMEOUT);
return;
}
