[Serusers] avp, selects question
by Luis Silva 05 Jul '06

05 Jul '06

Hi all! I'm trying to learn more about the new function added to ser, for manipulating the information inside the script. One problem that I found was when I tried to use %var1= "value1; %var1 +="value2; What I was trying to do was to get a value from a header field %auth_hdr = @hf_value.authorization; and then %auth_hdr += "something"; is it possible? (I got an error) then I tried another way $auth_hdr = @hf_value.authorization; %auth_hdr_something = "%$auth_hdr, something..."; and worked. but what is the difference between using that or using instead of $auth_hdr, use %auth_hdr. Can I do this: %auth_hdr_something = "%%auth_hdr, something..."; tks in advance

Hi, I have a problem with sending position coordinates with PUBLISH. If I send the x and y coordinates <x>01524.3441</x><y>04704.1020</y> via PUBLISH, SER cuts the last two digits (<x>1524.34</x><y>4704.1</y>). Why doesn't SER Notify the whole position? In which class does it cut the two digits? I hope, someone could help me. Best regards, Alois /usr/sbin/ser[11700]: handle publish request /usr/sbin/ser[11700]: get_pres_uri: _puri=sip:pda_user@fh-joanneum.at /usr/sbin/ser[11700]: handle_publish -4- p_uri= p_uri.len=23 /usr/sbin/ser[11700]: handle_publish -5- presentity=0x4069d1d8 /usr/sbin/ser[11700]: parse_pidf: sipuri=0x8216278:pres:pda_user@fh-joanneum.at contact=0x8216098:sip:pda_user@10.0.0.3 basic=0x82160b8:online location=(nil):(null) /usr/sbin/ser[11700]: parse_pidf: site=(nil):(null) floor=(nil):(null) room=(nil):(null) /usr/sbin/ser[11700]: parse_pidf: x=0x821be28:01524.3441 y=0x821be38:04704.1020 radius=(nil):(null) /usr/sbin/ser[11700]: find_presence_tuple: _p=0x4069d1d8 _p->tuples=0x4069d488 /usr/sbin/ser[11700]: publish_presentity_pidf: -1- /usr/sbin/ser[11700]: publish_presentity: -2- /usr/sbin/ser[11700]: publish_presentity: -3-: changed=1 /usr/sbin/ser[11700]: db_update_presentity starting: use_place_table=1 presid=4 /usr/sbin/ser[11700]: db_update_presentity: tuple- contact=sip:pda_user@10.0.0.3 len=21 basic=1 expires=1150916054 priority=0.500000 /usr/sbin/ser[11700]: db_update_presentity: cleaning contact from table /usr/sbin/ser[11700]: db_update_presentity: room= loc= /usr/sbin/ser[11700]: publish_presentity: -4- /usr/sbin/ser[11700]: publish_presentity: event_package=1 -1- /usr/sbin/ser[11700]: handle_publish -8- paerrno=0 /usr/sbin/ser[11700]: handled publish /usr/sbin/ser[11708]: timer_presentity: _p=0x4069d1d8 pda_user(a)fh-joanneum.at flags=1 watchers=0x4069d3a8 /usr/sbin/ser[11708]: notifying esca(a)fh-joanneum.at _p->flags=1 _w- event_package=1 _w->accept=2 _w->status=1 PUBLISH sip:pda_user@fh-joanneum.at SIP/2.0..Via: SIP/2.0/UDP 10.0.0.3:5060;branch=z9hG4bK874819433..Max-Forwards: 70..From: <sip:pda_user@fhjoanneum .at>;tag=540877786..To: <sip:pda_user@fh-joanneum.at>..Call-ID: 996402808-569651771- 701518565..CSeq: 10 PUBLISH..Contact: <sip:pda_user@10.0.0.3>..Con tent-Type: application/cpim-pidf+xml..Content-Length: 396..Expires: 50..Event: presence..User- Agent: SIP .NET 1.0 evaluation version, www.independents oft.com....<?xml version="1.0" encoding="utf-8"?><presence xmlns="urn:ietf:params:xml:ns:pidf" entity="pres:pda_user@fh-joanneum.at"><tuple id="9da019 ef-d0ea-4de0-8ad3-edacae0ca89c"><status><basic>online</basic><geopriv><locationinfo>< civilAddress><x>01524.3441</x><y>04704.1020</y></civilAddress></ location-info></geopriv></status><contact priority="0.8">sip:pda_user@10.0.0.3</contact></tuple></presence>.. 10.15.200.57:5060 -> 10.15.200.136:5060 NOTIFY sip:esca@10.15.200.136 SIP/2.0..Via: SIP/2.0/UDP 10.15.200.57;branch=z9hG4bK766a.c7db8933.0..To: <sip:esca@fhjoanneum. at>;tag=z9hG4bK29818902. .From: <sip:pda_user@fh-joanneum.at>;tag=589230a54cd08b3768529724501fae28-f2af..CSeq: 10 NOTIFY..Call-ID: 603541788327@10.15.200.136..Content-Length: 464..User-Agent: Sip EXpress router(0.9.3 (i386/linux))..Event: presence..Content-Type: application/pidf+xml..Subscription-State: active;expires=3479. ...<?xml version="1.0"?>..<!DOCTYPE presence PUBLIC "//IETF//DTD RFCxxxx PIDF 1.0//EN" "pidf.dtd">..<presence entity="sip:pda_user@fh-joanneum.at">..< tuple id="9r28r49">tid6e65cf14">.. <contact priority="0.500000">sip:pda_user@10.0.0.3</contact>.. <status>.. <basic>open</basic>.. <geopriv>< location-info><civilAddress> <x>1524.34</x>.. <y>4704.1</y>.. </civilAddress></location-info></geopriv>.. </status>.. </status>..</tupl e>..</presence>..

[Serusers] SER / MediaProxy / B2BUA
by Daniel Salama 05 Jul '06

05 Jul '06

After reading this forum: http://www.voipuser.org/forum_topic_4468.html it made me wonder, whether or not you really need B2BUA if you already have Mediaproxy in your environment. I know the purpose of Mediaproxy is to help with NAT situations. However, given the fact that Mediaproxy is always in the media path, couldn't it be ALSO used to "terminate" a call in progress, the same way that B2BUA can? And by B2BUA I refer to the Asterisk B2BUA, all within the context of prepaid type services. Any comments? Thanks, Daniel

[Users] How can i do accounting in such case
by tele 05 Jul '06

05 Jul '06

Hi all, In the traditional telephony who owned the call is the caller and is it possible for the caller to change the thorn without lost conversation but after 60sec if the call doesn't live, the central of caller disconnect the call. My test: I call from my UA to PSTN and during the call i disconnect my UA from IP connection. in my ethereal i can see now only RTP traffic from PSTN try to reach my UA, but after minutes nothing happen. note that i'm not using an rtpproxy right now. maybe with an rtpproxy it works and disconnect the call. my question is how can i generate accounting for the call if my UA disconnect the ethernet cable? the rtpproxy disconnect the call and generate the BYE for the accounting of the call. is it correct? hmm with a b2bua i can solve this issue but if i can do this only with openser is more better. anyone incurred if this kind of issue? thanks

[Serusers] IP address spoofing
by Nick Hoffman 05 Jul '06

05 Jul '06

Hi guys. Say you have this setup, with an account for the caller on both Asterisk and SER: Caller -> SER -> Asterisk -> VoIP Provider -> Callee If the caller were to spoof SER's IP address and place a call directly to Asterisk (thus circumventing SER), what would happen? If the call was in fact setup, obviously the caller would not receive any audio from the callee. However, would the call be setup? When Asterisk responds to the caller's request and sends SIP packets back (to SER), would SER say "I don't know anything about this call! Asterisk, kill this call please."?

[Serusers] SER in the message path
by Nick Hoffman 05 Jul '06

05 Jul '06

Several sources have told me that, once a call has been established, SER does not stay in the message path between the caller and callee. However, after examining some packet traces in Ethereal, I'm a little confused. I have the following setup: Caller -> SER -> Asterisk -> VoIP Provider -> Callee When I start tcpdump on Asterisk and place a call to the PSTN, the only devices that Asterisk is sending data to and receiving data from are SER and the VoIP provider. Doesn't this mean that SER does in fact stay in the SIP message path for the duration of a call?
