[Serusers] Inserting SER into my voice network
by Ray Van Dolson 31 Oct '05

31 Oct '05

First off, here is my voice network layout currently: http://webdev.digitalpath.net/~rayvd/voice/voice_network2.png We're using Asterisk for voicemail, call routing (for long-distance, LNP, etc) and SER/rtpproxy at the other end which handles NAT onto private networks where customer's exist. This setup works fairly well for the most part, except that Asterisk does not have a jitter buffer. I would like to make use of rtpproxy (or mediaproxy) for their jitter buffer on both ends of our voice links here. To me, that would mean shoving a SER/rtpproxy combo between Asterisk and our provider network. Possibly on the same server. I could easily throw up a SER installation, but I'm trying to figure out if there's any way to leave Asterisk in the SIP path but remove it from the media path (have RTP just go straight from SER/rtpproxy to my provider's RTP proxy). Have any of you set up a scenario somewhat like this? Any recommendations? Asterisk CVS-HEAD does let you apply a patch and get some very alpha jitter buffer support. But CVS HEAD doesn't work reliably for me at all currently so I'm sticking with the latest stable release of 1.0.x series. I'm running SER 0.9.3 FYI on the SER proxies I have set up currently.

[Serusers] LDAP authentication (without Radius)
by Felipe Louback 27 Oct '05

27 Oct '05

I'm working in a VoIP solution here in my university and we have a wide LDAP base and I am thinking about using it for I found on the internet Ldap/Ldaps modules for SER (http://www.ethworld.ethz.ch/technologies/sipeth/ser_modules/ldaps), but I am afraid that I could only use them for lookups and not direct authentication. I guess I could use radius for authentication but I dont know if installing a radius server "just" for this would be worth the effort. Does anyone know if there is a way to authenticate users in a LDAP server without using Radius? I mean, could I use SER directly with LDAP without using RADIUS?

[Serusers] fee-for-service SER server
by Michael Kendall 26 Oct '05

26 Oct '05

Dear Wizards, Many of you seem to be running public SER servers with hundreds of users. I would like to become a paying customer of such a SER server, but cannot find any such services advertised on the internet. Can someone please recommend a running, fee-for-service SER server? A few weeks ago, I asked this same question, and got zero responses. And I mean no responses of any kind. Is this the wrong forum to ask such a question? Even messages pointing out why I am a total idiot would have been preferable to total silence. If there are reasons that it is not practical for anyone to operate a fee-for-service SER server, I would love to see some discussion of what makes it so impractical. Please feel free to speculate on why you think such services have not been created. thanks, Michael

Hi Nhadie. I'm using the autoprovisioning system with PAP2 and Sipura. I don't know if the other phones have this feature. I also know that SJPhone can have this feaure too.

[Serusers] RTP proxy between two subnetworks with private @s
by Jose Soler 19 Oct '05

19 Oct '05

Hi, I am trying to figure out how to solve the follwoing problem. I have two subnetworks, A and B, with different private ip adressing schemes (IP@A <mailto:IP@A> ) and (IP@B <mailto:IP@B> ). SER is installed in a computer with network interfaces towards both subnetworks. SER's SIP signalling proxying operation works properly within the subnetworks and when trying to set up a communication between users in A and B. But in that last case, obviously there is no media at all circulating among the subnetworks. Portaone's RTP proxy has been installed and configured in the computer with interfaces towards both subnetworks where SER is installed. I am trying to configure SER so that, based on the nathelper module, when communication between both subnetworks occurs, the RTP proxy is involved and the communication (also media and not only signalling) is possible. BUT I am making something wrong, becouse it does not work ... Can anyone give me a hand /hint? Thanks a lot in advance / in any case. My SER config file is the following: # # ----------- global configuration parameters ------------------------ /* Uncomment these lines to enter debugging mode debug=7 fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) fifo="/tmp/ser_fifo" fifo_mode=0662 alias=wirelessip.x.x.x alias=sip..x.x.x alias=x.x.x log_stderror=no debug=3 children=3 mhomed=1 # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/lib/ser/modules/mysql.so" loadmodule "/lib/ser/modules/sl.so" loadmodule "/lib/ser/modules/tm.so" loadmodule "/lib/ser/modules/rr.so" loadmodule "/lib/ser/modules/maxfwd.so" loadmodule "/lib/ser/modules/usrloc.so" loadmodule "/lib/ser/modules/textops.so" loadmodule "/lib/ser/modules/registrar.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/lib/ser/modules/auth.so" loadmodule "/lib/ser/modules/auth_db.so" # For NAT support / media proxying loadmodule "/lib/ser/modules/nathelper.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- #modparam("usrloc", "db_mode", 0) # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line modparam("usrloc", "db_mode", 2) # -- auth params -- # Uncomment if you are using auth module modparam("auth_db", "calculate_ha1", yes) # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # For NAT # We will use flag 6 to mark NATed contacts modparam("registrar", "nat_flag", 6) # Enable NAT pinging modparam("nathelper", "natping_interval", 60) # Ping only contacts that are known to be # behind NAT modparam("nathelper", "ping_nated_only", 1) # ------------------------- request routing logic ------------------- # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; # special handling for NATed clients; first, nat test is # executed: it looks for via!=received and RFC1918 addresses # in Contact (may fail if line-folding used); also, # the received test should, if complete, should check all # vias for presence of received if (nat_uac_test("3")) { # allow RR-ed requests, as these may indicate that # a NAT-enabled proxy takes care of it; unless it is # a REGISTER if (method == "REGISTER" || ! search("^Record-Route:")) { log("LOG: Someone trying to register from private IP, rewriting\n"); # This will work only for user agents that support symmetric # communication.
