Re: [Serusers] Multihomed SER & NAT
by Sebastian Gabris 10 Aug '06

10 Aug '06

Thanks for the response, will try it and see what happens. :-) While waiting for help, i tried a new config, without fix_nat_contact. It works (Audio & signalling) for outgoing calls.(private -> public) Contact header has a private IP but SDP information is correct due to RTPProxy. At incoming calls the force_rtp_proxy command didn't change anything, meaning that SDP Information is not correct -> no audio, only signalling. I tried to start rtpproxy without options and in bridged mode. Also in bridged mode i tried both possibilities -l private/public & -l public/private, but it didn't influence the outcome. Perhaps someone could help me out on this. :-) Here are the changes to my config. route[1] { if(dst_ip == 10.x.x.x) { force_rtp_proxy("","193.x.x.x"); }; if (dst_ip == 193.x.x.x) { force_rtp_proxy("","10.x.x.x"); }; t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; } onreply_route[1] { if (status =~ "(183)|2[0-9][0-9]") { if(dst_ip == 10.x.x.x) { force_rtp_proxy("e"); log(2,"RTP_PROXY: Reply-Route1 dst 10.x.x.x\n"); }; if (dst_ip == 193.x.x.x) { force_rtp_proxy("i"); log(2,"RTP_PROXY: Reply-Route1 dst 193.x.x.x\n"); }; }; } fix_nated_contact() is meant for changing the IP address of the Contact > header when SER has a public address and the UA has a private (i.e. > behind NAT).

[Serusers] Same aliases for diferent subscribers
by Ricardo Carvalho 10 Aug '06

10 Aug '06

Hi, Is it possible to give same alias to different subscribers? Trying to add same alias in serctl isn't well succeeded because it says that that alias is already in use by other user. Is it any other way to do it? Regards, Ricardo.

[Serusers] How to change display name
by Steve Blair 10 Aug '06

10 Aug '06

Is it possible to change just the display name portion of the from header? I'm trying to implement caller ID blocking but we cannot remove the actual from URI because that breaks our gateway based CDR generation. I'm hoping changing the from header to something like: from="Anonymous" <sip:376826@myschool.edu>;tag=003094 Thanks, Steve -- ISC Network Engineering The University of Pennsylvania 3401 Walnut Street, Suite 221A Philadelphia, PA 19104 voice: 215-573-8396 215-746-8001 fax: 215-898-9348 sip:blairs@net.isc.upenn.edu

After reading a bit more mails, I came to two possible problems: 1. fix_nated_contact() needs a registrar to work properly I dont use a registrar, since i register at the VoIP - Provider. or 2. fix_nated_contact() is not ment to be used on this scenario Any ideas on this?

[Serusers] Multihomed SER & NAT
by Sebastian Gabris 10 Aug '06

10 Aug '06

Hi everybody, need some help on nattraversal. i use a multihomed SER, one private IP & one public IP. MyUA(privateIP) <-> (privateIP)SER(publicIP) <-> UA-(VoIP - Provider, pubicIP) If i try to make a call from private net to public net, SER doesnt change the contact address. He changes the sdp - connection field but he, puts in the wrong IP - address. Instead o writing down his public IP, SER writes his private IP. Then SER forwards the call on his public interface to the provider, which will get wrong Contact & SDP information. After reviewing my logs i saw that SER does the nat_uac_test, but the fix_nat_contact & fix_sdp dont work dont do what they should do :) Here are the important bits of my config: fork=yes log_stderror=no mhomed=1 listen=10.x.x.x listen=193.x.x.x loadmodule "/usr/lib/ser/modules/nathelper.so" modparam("usrloc", "db_mode", 0) modparam("registrar", "nat_flag", 6) modparam("nathelper", "natping_interval", 30) # Ping interval 30 s modparam("nathelper", "ping_nated_only", 1) # Ping only clients behind NAT if (nat_uac_test("3")) { if (method == "REGISTER" || ! search("^Record-Route:")) { log(2,"LOG: Someone trying to register from private IP, rewriting\n"); fix_nated_contact(); # Rewrite contact with source IP of signalling if (method == "INVITE") { fix_nated_sdp("1"); # Add direction=active to SDP }; force_rport(); # Add rport parameter to topmost Via setflag(6); # Mark as NATed }; }; ... and so on. ______________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!

[Users] two phones ringing
by Mark Kent 10 Aug '06

10 Aug '06

I've got two Linksys phones (one spa3000, one spa942) and registered markkent@... from both on the openser1.0.1 box. >From a third device I call markkent@... and both ring. If I take my time answering one phone then everything works as expected. The CANCEL gets sent to the second phone and that phone says OK and maybe I get one spurious ring but it stops. I noticed that if I answer one phone really quickly then the other phone will keep on ringing. So, I looked at the traffic and this is what happens: The players are ORIGINATOR, OPENSER, ANSWEREDPHONE and IGNOREDPHONE ORIGINATOR sends the INVITE to OPENSER where it gets branched out to both ANSWEREDPHONE and IGNOREDPHONE Both phones send back "100 Trying" ANSWEREDPHONE sends "180 Ringing" and OPENSER relays that to ORIGINATOR ANSWEREDPHONE sends "200 OK" when I answer, and OPENSER relays that to ORIGINATOR OPENSER sends "CANCEL sip:markkent@IGNOREDPHONE-IP:5062" to IGNOREDPHONE about 0.6 seconds later OPENSER repeats the CANCEL IGNOREDPHONE sends back to OPENSER 481 Call Leg/Transaction Does Not Exist and does it twice, perhaps once for each CANCEL Then IGNOREDPHONE sends back "180 Ringing" IGNOREDPHONE rings, a lot, but does not send back "180 Ringing" messages There are a lot of "200 OK" messages exchanged between the IGNOREDPHONE and the OPENSER box. The IGNOREDPHONE took 5 seconds to send back the first "180 Ringing", these phones are side by side, although IGNOREDPHONE (the 942) is NAT'ed and ANSWEREDPHONE is not. The ngrep output is here: http://a.mainstreet.net/double-ring.txt What I would like to know is whether this is something I can and/or should handle in the openser configuration? If so, how? Thanks, -mark

Re: [Serusers] Call between two SER Server
by Andrey Kouprianov 10 Aug '06

Hi, 1. In your "domain" table (i.e. MySQL) in both SER's you'd have to add domain entries. E.g. # serctl domain add you.domain.name.net 2. Then into" trusted" tables add entries as follows: a. For 192.168.100 --> Login to MySQL, and insert entries into SER's trusted table: mysql> insert into trusted values ('192.168.200.200', 'any', '^sip:.*$'); b. And vice versa. 3. After that you need to modify ur ser.cfg whenever INVITE method is encountered: E.g. ... if(!allow_trusted() && !is_uri_host_local() ) { if (!proxy_authorize("you.domain.name.net","subscriber")) { proxy_challenge("you.domain.name.net","0"); break; } else if (!check_from()) { xlog("L_WARN", "[%Tf]:%rm: possible uri spoofing attempt!; IP=%is; from=%fu; to=%tu\n"); sl_send_reply("403", "Forbidden"); break; }; consume_credentials(); }; .... Before saving make sure these modules are properly loaded: uri_db.so, domain.so, permissions.so and xlog.so. 4. Then restart your restart your SER Hope that works. Andrey.
