Music on Hold (MOH)

Execution of Call Pickup

This is the modified source code:

sdpLineNum_iterator_init(&iterator);

while ((a = get_sdp_iterate(&iterator, req, "a"))[0] != '\0') { char* mimeSubtype = ast_strdupa(a); /* ensures we have enough

space */

if (!strcasecmp(a, "sendonly")) { sendonly=1;

continue;

}

/* condition added by VGarroy to test MOH */ if (!strcasecmp(a, "inactive")) {

sendonly=1;

continue;

}

if (!strcasecmp(a, "sendrecv")) { sendonly=0;

}

if (sscanf(a, "rtpmap: %u %[^/]/", &codec, mimeSubtype) != 2) continue;

if (debug)

ast_verbose("Found description format %s\n", mimeSubtype);

/* Note: should really look at the 'freq' and '#chans' params

too */

ast_rtp_set_rtpmap_type(p->rtp, codec, "audio", mimeSubtype);

if (p->vrtp) ast_rtp_set_rtpmap_type(p->vrtp, codec, "video",

mimeSubtype);

}

To compile the changes into the system, complete the following steps:

1.Go to the folder containing the source files (default: /usr/src/asterisk/).

2.Execute the commands make and make install.
