Hey,
Apparently the list did not accept the previous message...
Here is the code you suggested with my modifications, it'll help put the log extracts in context :
else if ( dst_port == 5060 ) { xlog("L_INFO", "Publish rewritten forwarded for ext=$tU ruri=$ru duri=$du body=$rb"); subst_body('/group1[.]//g' ) ; t_relay("udp:127.0.0.1:5050"); exit ; } else { xlog("L_INFO", "Publish accepted for ext=$tU ruri=$ru duri=$du body=$rb"); handle_publish(); t_release(); exit;
}
Here is an expert from the /var/log/messsages :

But the phone's syslog shows this :

Everything is good, but notice the entity is somehow back to group1.105.
Where do you want me to run the traceroute? On the server?

Hey,
I tried that, but it did not seem to change anything. I saw the message change on the second loop, but it seems that the presence module figure out my tactic and fixed the message.
That's not possible. The presence module does not alter the received body. I think the problem is somewhere else.
Can you send me a trace?
ngrep -t -P "" -W byline -d any port 5060

That does not work: presence_server always uses the original received body, the modifications applied by you are not seen by the presence server.
The workaround would be to "loop" the modified PUBLISH to Kamailio again, e.g.:
listen=.......:5060 listen=.......:5050
route{ ... if (is_method("PUBLISH")) { if (dst_port==5060) { subst_body('/group1[.]//'); t_relay("udp:127.0.0.1:5050); } else if (dst_port==5050) { handle_publish(); t_release(); } } ... }

Hey,
I tried doing a subst or replace_body_all to change the entity="" value,
if (is_method("PUBLISH") ) { subst_body('/group1[.]//'); handle_publish(); t_release(); }
It did not work, the $rb variable still shows the old body and the NOTIFY received on the phone is the old body as well.
I thought about doing a string replace on the outbound NOTIFY but it never hits my routing script, so I can't.
I read textops and it does not list any limitations relating to me.
Any ideas?

I think the problem lies within the dialog module. Dialog module stores from/to URI. Both, from and to URI are derived from the headers. We could extend the dialog module to store request-URI in the dialog-info structure too, and add an option to pua_dialoginfo to use RURI instead of To-URI.

Hey,
I think I am doing something wrong, because here is the NOTIFY that comes to the phone :
NOTIFY sip:group1.101@my.home.ip:57234 SIP/2.0 Via: SIP/2.0/UDP my.kamailio.ip;branch=z9hG4bK3cab.78e494a4.0 To: sip:group1.101@my.kamailio.domain.name;tag=b2514519391e8b4d From: sip:102@my.kamailio.domain.name;tag=6d6077e15fecee48b2721a5e94bf8883-f712

The phone ( I tested with a GXP2000, GXP2020 and SPA962 + SPA932) does not flash lights or anything. Since you suggested that a solid kamailio would work out of the box, I suspect that either I miscommunicated my setup or did something really wrong. The notify definitely gets to the phone and the phone replies 200/OK when it receives the NOTIFY. But I think that the telephone is not understanding the request because it subscribed to '102' but received a notification for 'group1.102'. The funny thing is, the From header matches the subscribe To header, it's just the XML has the full name instead of the shortened name.
To: sip:102@my.kamailio.domain.name;tag=6d6077e15fecee48b2721a5e94bf8883-f712
I see this in my ( on kamailio ) /var/log/messages :
Aug 13 09:55:24 kamailio-dev /usr/sbin/kamailio[25449]: INFO:presence:send_notify_request: NOTIFY sip:group1.101@my.kamailio.domain.name via sip:group1.101@my.home.ip.where.phone.is:57234 on behalf of sip:102@my.kamailio.domain.name for event dialog
I should also mention that the NOTIFY sent out by presence bypasses my routing scripts. So I have the PUBLISH come through ( which I leave alone ) and the NOTIFY is sent according to the location table without ever consulting my routing script.
So everything amazingly worked out well, except that the lights are not changing status which I think is related to the XML document dialog-info entity attribute containing the group name, sent from my server.
Any ideas or suggestions ?
Thanks,
David
