[Serusers] SER with nathelper & rtprpoxy - how to disable rtpproxy when two phones are behind the SAME NAT
by Arek Bekiersz 15 Jun '06

15 Jun '06

Hi, Not sure if such issue was discussed before. Is this possible to detect that two phones are behind the same NAT, to avoid forcing rtpproxy in SER? This way we let the phones to send media directly to each other in private network behind NAT. Imagine two SIP phones connected to WAN using router with NAT. Both phones are in the same private network. Both phones have accounts on SER proxy, that in turn runs nathelper and rtpproxy. Phone_1 <--> NAT <--> SER,nathelper,rtpproxy Phone_2 <--> Normally when we make call between Phone_1 and Phone_2 using SER, RTP media will flow from Phone_1 to rtpproxy and back to Phone_2. Well, this is basically what we expect from rtpproxy & nathelper :-) Now somehow we could be able to detect in SER that both phones are behind the SAME NAT. When such situation is confirmed, we do not use nathelper and rtpproxy. As a result the phones send RTP media directly between them in private network, not using (and probably saturating) the poor internet link. I was thinking about: 1) Standard detection of NAT-ed situation, and then 2) comparing source IP of INVITE from Phone_1 with Contact IP stored for Phone_2 in "location" table. If they match, both phones MAY be in the same private network and we do not use nathelper functions. Of course it would work only if there is no other NAT before the primary NAT (i.e. we do not have the double NAT situation or similar) -- Regards, Arek Bekiersz

[Serusers] Nedd Help Badly
by Nhadie 15 Jun '06

15 Jun '06

Hi All, I'm having problem that the rtpproxy is using 54% of my CPU. Unfortunately i don't have enough money to buy a newer server. Can I make it such a way that I will force only rtpproxy when the call is from a private top another private, but when a private goes to a public IP (like my PSTN gateway) I won't use rtpproxy. another prob of mine is that some phones don't have STUN configured on it, but I have a STUN server. The big clients Ihave pu STUN already, but still they're going to the rtpproxy, I tried this config if ((uri=~"^(sip:)?00[0-9]*@([a-z]+.)?mydomain.com") || (uri=~"^(sip:)?00[0-9]*@202.202.202.203")) { if (is_user_in("From", "world-pstn")) { if (isflagset(8)) {xlog("L_INFO", "Call to anywhere in the Worldn");}; if ((is_user_in("From", "onstun"))) { # Strip first to digits (00) strip(2); prefix("25050#"); rewritehostport("202.202.202.202:5060"); consume_credentials(); t_relay_to_udp("202.202.202.202", "5060"); break; } else { if (isflagset(6)) route(1); strip(2); prefix("25050#"); rewritehostport("202.202.202.202:5060"); #rewritehostport("202.202.202.202:5060"); consume_credentials(); t_relay_to_udp("202.202.202.202", "5060"); #t_relay_to_udp("202.202.202.202", "5060"); break; }; } else { if (isflagset(8)) {xlog("L_INFO", "Your not allowed to call PSTNn");}; sl_send_reply("404", "DENIED: USER NOT IN WORLD-PSTN"); break; }; which would detect if an extension is a member of the onstun it will not use rtpproxy, but the caller (using IP phone) cannot hear the called party but the call is connecting, hope anyone can help me, badly need it. Thank You Regards, Nhadie ________________________________________________ Message sent using UebiMiau 2.7

[Serusers] Multiple SERs sharing same database
by Nick Hoffman 15 Jun '06

15 Jun '06

If I have multiple SER servers, should they each have their own database, or can they all share the same database? They're all going to be for the same purpose and will have the exact same subscriber, alias, etc information.

[Serusers] Presentity & Rls databases
by İlker Aktuna \(Koç.net\) 15 Jun '06

15 Jun '06

Hi, In my Ser installation with mysql db, I see some tables for presentity and RLS such as; | presentity | | presentity_contact | | presentity_notes | | presentity_persons | | rls_subscription | | rls_vs | | rls_vs_names | But they are empty tables and seems that they are not used anyhow. How can I make use of these tables ? I wonder how to save presence info on db. Thanks for any information.

[Users] Building on Solaris10?
by Bret Schuhmacher 15 Jun '06

15 Jun '06

Hi all, I'm having problems loading the mysql module. Seems to be a linker issue - the debug says function floor isn't exported. Anything different required to build or load this module under Solaris10? Do I have to force a 64 bit link or something? The Makefile has a bunch of 64 bit stuff in it: gcc -fPIC -DPIC -g -O9 -funroll-loops -Wall -mcpu=ultrasparc -mtune=ultrasparc -DNAME='"openser"' -DVERSION='"1.0.1"' -DARCH='"sparc64"' -DOS='"solaris"' -DCOMPILER='"gcc 3.4.3"' -D__CPU_sparc64 -D__OS_solaris ..... All the other modules load just fine... Here's my openser stdout: 0(12978) loading module /usr/local/lib/openser/modules/mysql.so 0(12978) ERROR: load_module: could not open module </usr/local/lib/openser/modules/mysql.so>: ld.so.1: openser: fatal: relocation error: file /usr/local/lib/openser/modules/mysql.so: symbol floor: referenced symbol not found ldd shows this, but it's not very helpful: bash-3.00# ldd /usr/local/lib/openser/modules/mysql.so libz.so => /usr/lib/libz.so libc.so.1 => /lib/libc.so.1 libm.so.2 => /lib/libm.so.2 /platform/SUNW,UltraAX-i2/lib/libc_psr.so.1 I've played with LDFLAGS, LD_LIBRARY_PATH, etc. Any tips or pointers in the right direction would be welcomed if this rings a bell with anyone. Thanks in advance! Bret

[Users] Is this configuration possible?
by Kenny Chua 14 Jun '06

14 Jun '06

I'm trying to build Openser with these requirements. Sorry, for the newbie questions. I have 10 users and a PSTN gateway. Let's say each users makes a call for 10 minutes. Is it possible to just show 100 minutes being charged on the PSTN gateway instead of 10 seperate users? If that is possible. Would I need the B2BUA in asterisk to accomplish this? I read Asterisk at large. I was wondering besides using Asterisk for voicemail, what other functions are used with integrating asterisk and openser? __________________________________________________ Do You Yahoo!?
