Summary:                    "transmit_refer" builds REFER with no host in case
of anonymous call transfer
Description: 
In case of Anonymous call Invite comes with the following "From" field:

> From: Anonymous <sip:192.168.0.1>

Transfer is called without specifying host.

> exten => 1.,1,Transfer(100)


Refer is build in function "transmit_refer" (line 12683 of chan_sip
module)
----
/* Get just the username part */
if ((c = strchr(dest, '@'))) {
	c = NULL;
} else if ((c = strchr(of, '@'))) {
	*c++ = '\0';
}
if (c) {
	snprintf(referto, sizeof(referto), "<sip%s:%s@%s>", use_tls ? "s" : "",
dest, c);
} else {
	snprintf(referto, sizeof(referto), "<sip%s:%s>", use_tls ? "s" : "",
dest);
}
----

In mentioned case "dest" is "100" and "of" is "192.168.0.1".

So Refer-To filed contains "Refer-To: <sip:100>" without specifying host
address.

This looks like a configuration issue. The destination should be an IP
address, not an extension number. It may work is [100] is defined in
sip.conf, but you would probably need to specify the SIP/100.

Please use the asterisk-users mailing list or #asterisk IRC channel for
additional support.
