Duplicate of ASTERISK-17278

I'm acknowledging this issue, but there is very little support for chan_h323. I suggest you try migrating to chan_ooh323 in Asterisk 1.8 which has significantly more support from the community.

More than happy to lend a hand with this have a feature set on RB for it that works closing few bugs i like the way it interacts with gnugk this bug can be closed its a trivial over sight when implementing ipv6 in res_rtp see patch in ASTERISK-17278 ready for next rc

Hi, I was testing H323 today and found the same issue.
I am using asterisk 1.8.5 and as suggested by /usr/src/asterisk-1.8.5.0/channels/h323/README I installed pwlib_v1_10_0 and openh323_v1_18_0.

I found that the line printing the error was:
426:   ast_log(LOG_WARNING, "Unable to allocate %s socket: %s\n", type, strerror(errno));

So, since the call to "socket" was returning < 0, I set "af" to PF_INET (IPV4) and it works now. For some reason the function is called with af=-1.

I added this 3 lines at the beginning of the fucntion

static int create_new_socket(const char *type, int af)
{
       ast_verbose("af is: %d. Setting it to PF_INET.\n",af); /* added FB */
       af = PF_INET;  /* added FB */
       int sock = socket(af, SOCK_DGRAM, 0);
       ast_verbose("sock returned %d.\n",sock); /* added FB */


now when the call comes, on the console I see this, showing that "af" was -1, and that after setting it to PF_INET then sock is assigned a valid socket handle.

af is: -1. Setting it to PF_INET.
sock returned 42.

and the call is able to progress on the dial plan.

I hope this helps
Fabian
