[Serusers] TCP sessions
by Stefan Ljung (TN/EAB) 28 Aug '07

28 Aug '07

Is it possible to make the SER 0.9 (or 2.0) to reuse the listening TCP port , usually 5060, when it relays requests to the next SIP element in the network.

[OpenSER-Users] Group and directed call pickup
by Zahid Mehmood 28 Aug '07

28 Aug '07

Hi All, I am working on implementing group/directed call pickup and it is my understanding that this requires dialog state information. Can someone describe the best approach to implement this when using multiple proxies? We have multiple proxies that replicate registration information to each other. Is there a way to share the dialog information among multiple proxies? or should all calls be routed through one proxy? Also, does this require presence server? Thanks in advance. -- Zahid

[OpenSER-Users] sip_msg_cloner: cannot allocate memory
by laurent schweizer 28 Aug '07

28 Aug '07

Hello, I have 2 openser working on 2 diffrents server. The first is doing the full job, Registration, authentifications .... And the second is only used for SEMS so a very simple config file. the first is working perfectly but the second create me this night a memory error. He was working correcly more that 1 month and I don't think that the problem is a overload usage because during the night I have low traffic. ./openser[5429]: ERROR: t_newtran: new_t failed ./openser[5435]: ERROR: sip_msg_cloner: cannot allocate memory ./openser[5435]: ERROR: new_t: out of mem: mpath="/usr/local/lib/openser/modules" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "xlog.so" loadmodule "avpops.so" modparam("tm", "fr_inv_timer", 15000) modparam("tm", "pass_provisional_replies", 1) modparam("rr", "enable_full_lr", 1) children=60 disable_tcp=yes disable_dns_blacklist=yes disable_dns_failover=yes disable_dns_blacklist=true # modparam( "tm", "tw_append", "info_append:hdr[Content-Length];hdr[Content-Type];msg[body]") #modparam( "tm", "tw_append", "info_append:Content-Length=$avp(i:70);Content-Type=$avp(i:71);body=$avp(i:72)") modparam("tm", "tw_append", "billing:billingid=$avp(i:67);accountid=$avp(i:68);Remote-Party-ID=$avp(i:69);Pays=$avp(i:70)") avp_aliases="bid=i:67;acid=i:68;rp=i:69;pays=i:70" # ------------------------- request routing logic ------------------- route{ # xlog("L_ERR","BEGIN: call [$rm] ru[$ru] fu[$fu] tu[$tu] si[$si] ct[$ct]\n"); if (!mf_process_maxfwd_header("5")) { sl_send_reply("483","Too Many Hops"); return; }; if (msg:len >= max_len ) { sl_send_reply("513", "Message too big"); return; }; sl_send_reply("100","---- trining"); record_route(); # if (loose_route()) { # xlog("L_ERR","LOOSE_ROUTE: [$rm] ru[$ru] fu[$fu] tu[$tu] si[$si] ct[$ct]\n"); # } if (!t_newtran()){ sl_send_reply("500","could not create transaction"); return; }; if (method=="INVITE"){ $avp(i:67) = $hdr(x-billingId); $avp(i:68) = $hdr(x-accountcode); $avp(i:69) = $hdr(Remote-Party-ID); $avp(i:70) = $hdr(Pays); if (uri =~ "sip:.*@") { if (!t_write_unix("/tmp/sems_sock","billing/billing")){ log("could not contact media server\n"); t_reply("500","could not contact media server"); return; } return; } # if (method=="INFO") { # $avp(i:70) = $cT; # $avp(i:71) = $cl; # $avp(i:72) = $rb; # # if(!t_write_unix("/tmp/sems_sock","sems/info_append")){ # log("could not contact sems\n"); # t_reply("500","could not contact media server"); # } # } } if (method=="BYE" || method=="CANCEL"){ if(!t_write_unix("/tmp/sems_sock","bye")) t_reply("500","error contacting bye"); } return; }

[Serusers] SIP-based multipoint video conferecing?
by SIP 28 Aug '07

28 Aug '07

Is anyone aware of, or does anyone have any experience with any SIP-based multipoint (i.e. more than 2 users) video conferencing server software? Ideally, of course, I'd like an H263 codec module for SEMS, but barring that, another SIP server that I can easily mesh with SER, forwarding video requests as need be to the video conferencing server to handle just the video mixing. Anyone use anything like that in their environments? N.

[OpenSER-Users] AVP Iteration
by Brandon Armstead 28 Aug '07

28 Aug '07

Hello, I'm trying to setup some kind of iteration through an AVP list using recursive routing, and use an AVP to create an "index" incrementing counter, i.e. if(is_avp_set("$avp(counter)")){ $avp(counter) = $avp(counter) + 1; } else { $avp(counter) = 0; } then I wish to apply to an avp index likewise: if($avp(some_avp[$avp(counter)]) == null){ # this avp list index does not exist, stop recursive routing } else { # keep doing operations } However this is trivial, there seems not to be any easy way of going about this, also openser.cfg errors out when I try to nest AVP's and use an AVP value as an index value. xl_parse_index: error parsing format [$avp(counter)])] expecting ']' parse error (410,59-89): unknown script variable Any thoughts? All Appreciated, thank you! -- Brandon Armstead

Re: [OpenSER-Users] About RTP stream

Yin, here you have a proper configuration: http://openser.svn.sourceforge.net/viewvc/openser/branches/1.2/examples/nat… Just make sure you install rtpproxy and start it on the same host with your openser. If properly installed, openser should recognize it in the logs (found RTP proxy, support for it activated) Cheers, DanB On 8/28/07, zze-WU Yin RD-MAPS-LAN <yin.wu(a)orange-ftgroup.com> wrote: > Hi Dan, > > In fact, I have two telephones VOIP and Openser as a SIP Proxy (in the same local network,there's no NAT.), they can register and call each other with no probleme. Now I just need the stream RTP pass by Openser, but no directely between two telephone. I have installed the rtpproxy, but I don't understand how it works exactely.
