RE: [Serusers] Mediaproxy question : client_nat_test ().?

by Ricardo Martinez

Anyone on this one? Thanks again Ricardo.- -----Mensaje original----- De: Ricardo Martinez [mailto:rmartinez@redvoiss.net] Enviado el: Viernes, 17 de Diciembre de 2004 17:28 Para: SER Users (E-mail) Asunto: [Serusers] Mediaproxy question : client_nat_test ().? Hello List I have a question regarding the client_nat_test() in the mediaproxy module. If i have an INVITE something like this. INVITE sip:5555848114@mydomain.com SIP/2.0. Via: SIP/2.0/UDP sipgw.mydomain.com:5060; branch=z9hG4bKNxvDQVViBAAJAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA_. Via: SIP/2.0/TCP xx.xx.154.68:14123. From: <sip:22408100@sipgw.mydomain.com>;tag=3655298548. To: sip:5555848114@mydomain.com. CSeq: 1 INVITE. Call-ID: 3406152498(a)sipgw.mydomain.com. Contact: <sip:22408100@sipgw.mydomain.com>. Accept: application/sdp. Max-Forwards: 69. Content-Type: application/sdp. Content-Length: 200. . v=0. o=sipgw.mydomain.com 811562435 1354711274 IN IP4 xx.xx.154.36. s=SIP Library call. c=IN IP4 xx.xx.154.68. t=3312294794 0. m=audio 23264 RTP/AVP 18 4. a=rtpmap:18 G729/8000. a=rtpmap:4 g723/8000. How is possible to mediaproxy module detect this client as a NAT'd? Because all the calls coming from this GW are being proxied by mediaproxy. It suppose that this GW's has a public IP, so i don't understand why is this happening. Beside this can someone tell me if this is ok that a VIA parameter has a domain name ???? The snippet for my NAT'd mediaproxy enviroment is : if (client_nat_test("3")) { log(1, "NAT: Requerimiento de IP privada --> fixed contact (en rutina principal)\n"); setflag(5); force_rport(); fix_contact(); append_hf("P-hint: fixed NAT contact for request\r\n"); .... if (method=="INVITE") { log(1, "ROUTING: Reply processing (online user) enabled to handle NAT'd resonses\n"); t_on_reply("1"); if ( (isflagset(5)) && (method=="INVITE" || method=="ACK") ) { log(1, "NAT: Invite received --> enabling media proxy (else del lookup 2do if)\n"); use_media_proxy(); append_hf("P-hint: request forced to media proxy\r\n"); }; }; .... onreply_route[1] { # If we've got here, it's because we've previously passed through a block # which handles NAT requests and has set a t_on_reply condition. DB 03-08-2004 if (status =~ "(183)|(2[0-9][0-9])") { if (client_nat_test("3") || isflagset(5)) { log(1, "NAT: Reply from NAT'd client --> fixing contact (onreply_route)\n"); fix_contact(); use_media_proxy(); setflag(5); }; log(1, "NAT: NAT'd transaction answered --> enabling media proxy (onreply_route)\n"); # use_media_proxy(); }; } Thanks in advance. Best reegards, Ricardo.- _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers

[Serusers] Adding new user with serctl

by Steve Blair

I have been meaning to ask how other SER sites add new users to their system. It always seemed odd to me that serctl didn't provide a command line mode for adding the first_name, last_name and phone values. I've managed with such a mode but now that Help Desk staff will be creating user accounts I'd like to package the account creation process into one coherent step. How do other sites handle the account creation process? Have you developed your own tools or do you use serctl and mysql? Thanks,Steve

[Serusers] sip phones in different private networks have oneway audio

by Steven Wang

Hello I have one phone (phone1) in one network, the other (phone2) in public network. both can call the other side; phone1 can be heard by phone2, phone2 can't be heard. I don't have NAT set on both end, but I use rtpproxy on SER. Is NAT still necessary to be set on both phones? Thank you! steven

[Serusers] language syntax

by murat inal

dear all, i am an absolute newbie at SER, sorry if this is a more-than-essential question :) what do we basically code in ser.cfg? is it a script language? how can i learn the syntax of the language? and then we program SER with codes with remarks like "routing logic". how do we learn about the methods & functions used there? checked for documentation (like ser_howto) from iptel.org site, however they are inadequate? best,

[Serusers] ser and RADIUS

by proson.cheng＠kaisource.com

HI everyone, I am planning to configure SER with FreeRADIUS authentication and calls accounting. Do I need to have a RADIUS-enabled UA to use this feature properly? If not so, How does a UA register a domain and thus proceed calling? Many thanks. Proson

[Serusers] Problem with ACK

by Amozurrutia Jesus

I'm implementing the scenario shown below. ___ ______ / 0 \ ---/ \ | /_\ | ATA1 |---| ____ _ _ _ _ _____ \______/ | / \ / \/ \/ \/ \ / \ |---| FW |---| IP Net |---| CCM | | \____/ \_/\_/\_/\_/ \_____/ | | | | | | | | --- --- / \ / \ |NAT| |SER| |-T | | | \___/ \___/ When calling between the CCM (Cisco CallManager) and the ATA, SER simply ignores the call ACK. The ACK looks like: ACK sip:5559853979*sip1.mcm.net.mx=X.X.71.2+17081@X.X.81.92:5063 SIP/2.0 Via: SIP/2.0/UDP X.X.67.218:5060;branch=z9hG4bK29b2c750 From: "5559852600" <sip:5559852600@X.X.67.218>;tag=16781758 To: <sip:5559853979@mcm.net.mx>;tag=2602576443 Date: Tue, 30 Nov 2004 23:53:15 GMT Call-ID: fef8ed00-1da1612d-24d-da4334c8(a)X.X.67.218 Route: <sip:5559853979@X.X.81.94;ftag=16781758;lr> Max-Forwards: 70 CSeq: 101 ACK Content-Length: 0 The call flow: CallManager SIP Server ATA | | | |-- INVITE -------->| | |<-- trying --------| | | |-- INVITE -------->| | |<-- Trying --------| | |<-- Ringing -------| |<-- Ringing -------| | | |<-- OK ------------| |<-- OK ------------| | |-- ACK ----------->| | | |<-- OK ------------| |<-- OK ------------| | |-- ACK ----------->| | | |<-- OK ------------| |<-- OK ------------| | |-- ACK ----------->| | | |<-- OK ------------| |<-- OK ------------| | |-- ACK ----------->| | | |<-- OK ------------| ...... My guess is that SER does not accept the URI "5559853979*sip1.mcm.net.mx=X.X.71.2+17081@X.X.81.92:5063" because it contains "*+=" signs ore something similar. When calling from ATA - ATA there is no preoblem because ATAs construct the ACK message different (URI and Rote flipped). Any ideas? Thanks in advance, Jesus
