[Serusers] PA module + registration handling

by Dave Bath

Hey guys, Many apologies if im just being totally dense on this one, but I've been going back and forth for a few days now, and given how new the presence module is there doesn't seem to be huge amounts of documentation on it. I'm attempting to get the PA module for the latest (as of a few days ago) CVS to work. All other config bits in ser seem to work fine. I think perhaps my confusion is also about how it's supposed to work! Perhaps if I could ask some questions, people could fill in where they know the answers, or point me to the right place. I had in my config: if (method=="SUBSCRIBE" || method=="PUBLISH") { # BEGIN method==subscribe if (t_newtran()) { log(1,"PRESENCE: Change of state detected\n"); handle_subscription("registrar"); break; }; }; And like this, a presence aware client could register ok, and I could see from the debug outputs that they had registered, and when I tried to add new contacts to the "buddy list" subscribe requests were being issued. However, I have not yet seen any publish requests. Do I need to use the function handle_publish? Whenever this subscribe request happened, I see some errors in the syslog: Oct 5 10:59:52 sip ser[15409]: PRESENCE: Change of state detected Oct 5 10:59:52 sip ser[15409]: handle_subscription() entered Oct 5 10:59:52 sip ser[15409]: parse_hfs(): Error while parsing headers Oct 5 10:59:52 sip ser[15409]: handle_subscription(): Error while parsing message header Oct 5 10:59:52 sip ser[15409]: handle_subscription about to send_reply and return -2 Also, I am a bit confused about registrations... as there is the function pa_handle_registration... Originally I did not modify the registration code, but when I tried to add this: if (method=="REGISTER") { # BEGIN method==Register checking if(t_newtran()){ pa_handle_registration("registrar"); break; }; ... etc, before my regular registration code, normal (voice) clients could no longer register and I got errors such as : Oct 5 11:02:59 sip ser[15706]: parse_hfs(): Error while parsing headers Oct 5 11:02:59 sip ser[15706]: pa_handle_registration(): Error while parsing headers So I guess my question about that is, do presence-aware clients need to registered differently? And if so, how do you make sure you don't send your normal voice clients into that registration as well? Any guidance on how to these functions are supposed to integrate would be very very much appreciated. Many thanks in advance for all the help this list provides..

[Serusers] help setting SIP DOMAIN + error

by Ashling O'Driscoll

Hi, Hope someone can help with the following two queries: I've set up SER and its now running (I think!) in the background. I get the following: linux:/usr/local/sbin # ser Listening on 127.0.0.1 [127.0.0.1]:5060 192.168.3.77 [192.168.3.77]:5060 10.0.1.4 [10.0.1.4]:5060 However my SIP UA keeps trying to register on iptel.org so obviously I must set my own domain somewhere. I know it's something got to do with 'SIP DOMAIN' but where do I set that? Also im trying to set up a user using the serctl facility. Im getting the following errors (though this may be something to do with the fact that my domain isn't set): linux:/usr/local/sbin # export SIP_DOMAIN=foobar.com linux:/usr/local/sbin # serctl add newuser secret aisling(a)foobar.co MySql password: /usr/local/sbin/serctl: line 316: mysql: command not found /usr/local/sbin/serctl: line 311: mysql: command not found Im a Masters student who's struggling-Please help!! -------------------Legal Disclaimer--------------------------------------- The above electronic mail transmission is confidential and intended only for the person to whom it is addressed.

[Serusers] Mediagateway with STM1 connectivity

by Leon de Rooij

Hi, Right now we're using SER as proxy with Asterisk servers in combination with Digium Wildcard Quad-E1 cards for terminating our customers to our voice-switch. In the near future it may be more interesting to connect with STM-1 instead of E1's. What brands/products do other providers use as mediagateway ? And what products have a good price/quality ? Thanks, Leon de Rooij leon(a)scarlet-internet.nl

[Serusers] 487 not getting ACK

by Richard

Hi, I have a particular UA which can't seem to send the correct "487 request terminated". Hope that someone can help me here. The complete sip scenario is at http://o-matrix.org/sip/asf.html. The relevant call is from Phone A 66.175.65.82, via ser 66.175.65.80 to Phone B 66.135.241.191. When Phone A hangs up before B picking up, Phone A sends a CANCEL to ser. The problem happens when ser forwards the 487 from Phone B to phone A. It seems the message has some errors which cause Phone A not sending back ACK. I am pretty sure that this is a problem with the 487 sent by Phone B. I tested several other type of phones with Phone A and have no problem. But I can't figure out what's wrong with the 487 message from phone B. All headers of 487 seems to match the original INVITE. I noticed SIP packet F14 has "Extra Information: Packet is not a complete SIP message". Not sure about this. Thanks, Richard

[Serusers] some questions about SIP(IM and domain)

by C Y

hello everyone: I have some problems when I configure the SIP server.I hope you can help me to solve them. The first problem: when two users communicate with Windows Messenger 5.0(SIP),they cannot send Instant Messaging.How should I configurate the SIP server to surport it? The second problem:when a user login in the SIP system,the data of field "domain"( database "ser",table "location") is NULL.It should be "voipv6.edu.cn".So I cannot find the online user through SERWEB.What should I do to solve the problem?

RE: [Serusers] Avoiding storing passwords in mysql "subscriber" tablein clear-text

by Dave Bath

Hey Karl, It might be possible to use encrypted mysql passwords - someone else on the list seems to have mentioned that it might be possible, but I haven't used this before. Otherwise, use radius authentication and it's up to you how you get radius to store the passwords (which could be in a mysql database...) hope that helps slightly?!

[Serusers] NAT problems using netopia router but not cisco routers in REGISTER method

by Manuel Marin Garcia

I am trying to register a Sipura ATA to ser. I am using nathelper to fix contact in the register method. Probably Iam implementing nathelper in the wrong way but it works with a cisco router but not with a netopia or linksys router. I append SIP traces. Please help me! if (method=="REGISTER") { if (nat_uac_test("2")) { log(1, "Se detecta cliente con NAT src address different than via header\n"); fix_nated_contact(); append_hf("P-hint: fixed NAT contact for request\r\n"); }; if (!www_authorize("65.77.23.7", "subscriber")) { www_challenge("65.77.23.7", "0"); break; }; save("location"); break; }; The following trace is taken when the Sipura is using a netopia router. Sipura has IP address 192.168.1.50 and the public Ip address is 200.52.114.200. These messages are repeated too many times, I have the following question: * In the VIA header I see that Sipura is sending private IP address not public. Is that correct? Can I solve it using nathelper?
