[Users] Overlapping AVPs
by Andreas Granig 12 Apr '06

12 Apr '06

Hi, Me again, sorry, but the docs aren't really noisy about AVP details... So if I have user preferences for both the caller and callee and load them from DB and print them using the following: avp_db_load("$avp($uuid_caller)", ""); avp_db_load("$avp($uuid_callee)", ""); avp_print(); then they may overlap because of the same ID (say "i:102" for toggling some specific feature on/off), but according to the debug output both are present: INFO:avpops:print_avp: p=0x4056db90, flags=100 INFO: id=<102> INFO: val_int=<1> INFO:avpops:print_avp: p=0x4056dc68, flags=100 INFO: id=<102> INFO: val_int=<0> So is it possible to selectively access the avp-value of both $uuid_caller and $uuid_callee? Something like $avp(i:102)[0] and $avp(i:102)[1] maybe? Thanks, Andy

Does openser support T.38? Does it enable by default? >The problem with G.711 + FAX is concerned with variable delay and jitter... >Use T.38 or V.150 if enable... ;) >Edson.

[Users] Question regarding OpenSER behind NATs with NATed clients
by Justin Pearce 12 Apr '06

12 Apr '06

Greetings, I know it is probably a really newbie question, but is OpenSER able to negotiate the following situation: Server running OpenSER sits NATed behind a firewall. Clients sit on a separate network, NATed behind a firewall. Client systems send signaling information to the server to contact another client. Clients are capable of determining their own outside IP addresses. Client then connects media streams directly to other client. I'm trying to find out of this is possible and, if so, where might documentation for it be found, since my supervisor is asking me about it and I can't seem to find any relevant information on the topic (maybe my googling skills are not up to par). Any info would be greatly appreciated.

[Users] Force RTP stream to go through mediaproxy
by Sam Lee 12 Apr '06

12 Apr '06

Hi all, I got the openser and mediaproxy up working and fine. The mediaproxy is able to work with certain NATED configurations, but not all. When i tried to check what is the problem , those NATED configurations that were not working was found not to have made use of the mediaproxy, which causes the problem. What i am trying to do now, but without much success, is to force all the RTP media to go through the mediaproxy. Is there any way i can force all the RTP media to go through the mediaproxy without all the client_nat_test stuff...? Any hints will be much appreciated ! Regards, Sam

[Users] Media Proxy Problem
by Rafael Neves Harff 12 Apr '06

12 Apr '06

Hi all! Ive finished installing Openser + mediaproxy today. I have user Ozan Blotter post in the list (http://openser.org/pipermail/users/2005-July/000304.html) to configure the mediaproxy.It worked before without media proxy. Now I can authenticate, the same way I did before, but when I try to dial someone I get a message in the Softphone: Call failes: 407 Proxy Authentication Required What I'm doing wrong? Thanks for the help! --- Rafael Neves Harff from Brazil

[Users] function client_nat_test problem
by unplug 12 Apr '06

12 Apr '06

below is the configuration Internet --- openser (mediaproxy) ---- PSTN + public IP (203.13.14.210) + Internal IP (10.0.0.30) openser will list on both internal and external IP User can make/receive call without problem. user device --- NAT -------------------------------------- openser ---- PSTN (10.0.0.60) (202.130.10.200) (203.13.14.210) user device ------------------------------------------------ openser ---- PSTN (10.0.0.60) (10.0.0.30) User can receive call without problem. However, when user makes outgoing calls, problem will occur. 1. called party will ring but calling party without ring. 2. After pick up the phone, both parties can't hear any sound. >From the past experience, the problem should be caused by the NAT issue. In my dial plan, I use a module function client_nat_test("3"). if (method=="INVITE" && client_nat_test("3")) { # INSERT YOUR IP ADDRESS HERE record_route_preset("203.13.14.210:5060;nat=yes"); } else if (method!="REGISTER") { record_route(); }; >From the function description http://openser.org/docs/modules/devel/mediaproxy.html#AEN113, it will test if the client is behind NAT or not. However, in the result of ngrep, I can still find the header with the following. Record-Route: <sip:203.13.14.210:5060;nat=yes;ftag=nQvg2qq2fzNg24d1;lr=on> That's mean function client_nat_test always return true (from the case above) no matter client is behind NAT. It is what I find up to now. I would like to ask whether there is any other configuration variables needed for the NAT detection. How the mediaproxy module (based on what) to detect the device is behind NAT or not? Any clue is welcome.

[Users] Upgrade to 1.0.1 and usrloc alias isn't working.l
by Shane Burrell 12 Apr '06

12 Apr '06

I just upgraded to v 1.0.1 from 0.9.5 and now calls can be made from sip devices but calls coming from PSTN don't find a usrloc or alias and its sent back out by 10 digit check. I'm using MYSQL. What and were should I look for setting to make the following call work to a particular sip user from the TNT. lookup(): '8485974202(a)102.53.11.19' Not found in usrloc The TNT is sending the call to '8485974202(a)102.53.11.19' which appears to be correct in the alias file for user shane who has an entry in the location table. TIA, Shane ***************************************************************

[Users] multiproxy routing question
by HUANG Quan 12 Apr '06

12 Apr '06

Hi all, I wanna setup a simple sip voip system with two proxies, namely proxy1 and proxy2. Proxy1 handles the phone numbers between 1001 and 1999, and proxy2 handles the numbers between 2001 and 2999. Could anybody give me an example script to route sip messages between 1xxx and 2xxx?

Re: [Users] Fwd:Invalid table version
by buxalex＠libero.it 12 Apr '06

12 Apr '06

Hello Bogdan, as usual you are right! :o) I tried to use the table subscriber as follow: if (method=="INVITE") { setflag(2); record_route(); if (!lookup("subscriber")) { sl_send_reply("401", "Dialled Number not Authorizied"); exit; if (!lookup("location")) { sl_send_reply("404", "Dialled number off line !"); exit; }; }; Of course commenting the part related to subscriber table it works fine. My idea was to check whether the dialled number is only off line or it is not existent; this because I would like to have the choice to send a registered vocal message (or for mow an email) to dialled numbers. I tried to put 1003 in table domain and subscriber, but now I get this error: ACC - initializing AVPops - initializing submit_query: Unknown column 'contact' in 'field list' db_query: Error while submitting query preload_udomain(): Error while doing db_query register_udomain(): Error while preloading domain 'subscriber' domain_fixup(): Error while registering domain fix_actions: fixing failed (code=-1) at cfg line 211 ERROR: fix_expr : fix_actions error Can I fix this problem with configuration, or should I modify the logic to access the db (I mean I shouldn't use the subscriber table)?
