[osip-dev] can not start an audio call

[giovanni sandra]

Hello;

Please I need your help.

I am trying to make a call from my eXosip user agent to the linphone.

Every thing is ok, the call is received by the linphone.

But I can not start an audio conversation: when choosing to click on the accept button, the linphone

doesn't react.

I don't know where is the problem.

This is my code;
 if (i != 0)
    {
      printf ("Couldn't initialize eXosip!\n");

    }
  else
    {
      printf ("eXosip_init successfully!\n");
    }
i = eXosip_listen_addr (IPPROTO_UDP, NULL, 5061, AF_INET, 0);
  if (i != 0)
    {
      eXosip_quit ();
      fprintf (stderr, "Couldn't initialize transport layer!\n");
   //   return -1;
    }
 
      printf("\t***********************************************\n");
      printf("\t*****************Menu*************************\n");
      printf("\t***********************************************\n");
 
      printf ("\tVoici la liste d'actions que vous pouvez accomplir:\n r:s'enregistrer\n i: envoyer une requête invite \n  l: Rester en ligne \n  f: renvoyer un appel \n");
      printf ("\tSVP choissisez une commande :\n");
 
 
 scanf ("%c", &command);
      getchar ();
      int flag1=1;
      int flag = 1;
 while (flag)
 {
      switch (command)
    {
 
       case 'i':
printf ("\t Tapez SVP l'adresse de l'hôte que vous voulez joindre\n");

char ad;
scanf ("%s", &ad);

char *add=&ad;
 i = eXosip_call_build_initial_invite (&invite, add, source_call, NULL, "This is a call for a conversation");
 
 
          if (i != 0)
        {
          printf ("Initial INVITE failed!\n");
          
        }
osip_message_set_supported (invite, "100rel");
snprintf (tmp, 4096,
            "v=0\r\n"

Any help will be very grateful!
