Summary: [patch] Pickup with Aastra phones: Unable to find
subscription
Description:
Hello
With Asterisk 1.6.2, the directed pickup don't works with Aastra phones
(53/55/57/30/31i)
It works good with 1.4, 1.6.0, 1.6.1, but not with 1.6.2
The blf works good.
The pickup works good with "*8 + number".
When I press a blinking button, there is only that in CLI, and no pickup
on the phone:
NOTICE[5161]: chan_sip.c:19843 handle_request_invite: Unable to find
subscription with call-id: fb287af6461e248a
the "sip show subscriptions" command return the good call-id:
localhost*CLI> sip show subscriptions
Peer User Call ID Extension Last
state Type Mailbox Expiry
10.0.0.167 guillaume fb287af6461e248 746 at blf Idle
dialog-info+xml <none> 000360
2 active SIP subscription
Is the call-id truncated? (fb287af6461e248 => fb287af6461e248a )
I can "solve" the problem by replacing this two pieces of 1.6.2 chan_sip
by the same pièces of 1.6.1, this works but it's not a
solution:
1.6.2:
if ((state & AST_EXTENSION_RINGING) && sip_cfg.notifyringing) {
const char *local_display = p->exten;
char *local_target = mto;
/* There are some limitations to how this works. The primary one is that
the
callee must be dialing the same extension that is being monitored. Simply
dialing
the hint'd device is not sufficient. */
if (sip_cfg.notifycid) {
struct ast_channel *caller =
ast_channel_search_locked(find_calling_channel, p);
if (caller) {
int need = strlen(caller->cid.cid_num) + strlen(p->fromdomain) +
sizeof("sip:@");
local_target = alloca(need);
snprintf(local_target, need, "sip:%s@%s", caller->cid.cid_num,
p->fromdomain);
local_display = ast_strdupa(caller->cid.cid_name);
ast_channel_unlock(caller);
caller = NULL;
}
}
/* We create a fake call-id which the phone will send back in an INVITE
Replaces header which we can grab and do some magic with. */
ast_str_append(&tmp, 0,
"<dialog id=\"%s\" call-id=\"pickup-%s\" direction=\"recipient\">\n"
"<remote>\n"
/* See the limitations of this above. Luckily the phone seems to still
be
happy when these values are not correct. */
"<identity display=\"%s\">%s</identity>\n"
"<target uri=\"%s\"/>\n"
"</remote>\n"
"<local>\n"
"<identity>%s</identity>\n"
"<target uri=\"%s\"/>\n"
"</local>\n",
p->exten, p->callid, local_display, local_target, local_target, mto,
mto);
} else {
ast_str_append(&tmp, 0, "<dialog id=\"%s\">\n", p->exten);
}
1.6.1:
if ((state & AST_EXTENSION_RINGING) && global_notifyringing)
ast_str_append(&tmp, 0, "<dialog id=\"%s\" direction=\"recipient\">\n",
p->exten);
else
ast_str_append(&tmp, 0, "<dialog id=\"%s\">\n", p->exten);
1.6.2:
/* Try to find call that we are replacing.
If we have a Replaces header, we need to cancel that call if we succeed
with this call.
First we cheat a little and look for a magic call-id from phones that
support
dialog-info+xml so we can do technology independent pickup... */
if (strncmp(replace_id, "pickup-", 7) == 0) {
struct sip_pvt *subscription = NULL;
replace_id += 7; /* Worst case we are looking at \0 */
if ((subscription = get_sip_pvt_byid_locked(replace_id, NULL, NULL)) ==
NULL) {
ast_log(LOG_NOTICE, "Unable to find subscription with call-id: %s\n",
replace_id);
transmit_response_reliable(p, "481 Call Leg Does Not Exist (Replaces)",
req);
error = 1;
} else {
ast_log(LOG_NOTICE, "Trying to pick up %s@%s\n", subscription->exten,
subscription->context);
ast_copy_string(pickup.exten, subscription->exten,
sizeof(pickup.exten));
ast_copy_string(pickup.context, subscription->context,
sizeof(pickup.context));
sip_pvt_unlock(subscription);
if (subscription->owner) {
ast_channel_unlock(subscription->owner);
}
}
}
/* This locks both refer_call pvt and refer_call pvt's owner!!!*/
if (!error && ast_strlen_zero(pickup.exten) && (p->refer->refer_call =
get_sip_pvt_byid_locked(replace_id, totag, fromtag)) == NULL)
{
ast_log(LOG_NOTICE, "Supervised transfer attempted to replace
non-existent call id (%s)!\n", replace_id);
transmit_response_reliable(p, "481 Call Leg Does Not Exist (Replaces)",
req);
error = 1;
} else {
refer_locked = 1;
}
1.6.1:
/* Try to find call that we are replacing
If we have a Replaces header, we need to cancel that call if we succeed
with this call
*/
if ((p->refer->refer_call = get_sip_pvt_byid_locked(replace_id, totag,
fromtag)) == NULL) {
ast_log(LOG_NOTICE, "Supervised transfer attempted to replace
non-existent call id (%s)!\n", replace_id);
transmit_response_reliable(p, "481 Call Leg Does Not Exist (Replaces)",
req);
error = 1;
} else {
refer_locked = 1;
}
/* At this point, bot the pvt and the owner of the call to be replaced is
locked */
I've searched and found news things about pickup with asterisk 1.6.2:
http://www.mail-archive.com/asterisk-users@lists.digium.com/msg234379.html
http://lists.digium.com/pipermail/asterisk-users/2010-February/244771.html
http://www.asterisk.org/doxygen/asterisk1.6.2/chan__sip_8c.html (search
"Unable to find subscription with call-id" in the page)
Maybe not really a bug, but a significant change which blocks an essential
feature.

----------------------------------------------------------------------
Tried with the Thomson ST2030 phone:
With pedantic=yes, pickup always fails, either patched or unpatched *
(1.6.2.6/1.6.2.7).
With pedantic=no: Pickup works OK, also with unpatched *. So it is a
configuration issue with the ST2030, too. Should be fixed for pedantic=yes,
though. What should I provide to help with that?
BUT: This pickup is completely different from what we had till 1.6.1.x: It
works inside the SIP dialog without the dialplan having any control on the
pickup. Even callgroup/pickupgroup are w/o effect here, so we have no
control about who is allowed to pickup.
The above patch from xxxxxxx restores the 'old' behaviour, where the phone
would dial *8XXX and one would be able to deal with that in the dialplan.
