Yes, but, if UA is behind symmetric NAT, I would not configure STUN to it. I'd just led mediaproxy solve the problem.

[Serusers] Tags, forwarding, redirects, and picky UACs

by Alistair Cunningham

I'm trying to implement forwarding to voicemail with a UAC that's picky about the tags in the To: headers it receives. First, I tried the following: failure_route [1] { rewritehostport("192.168.1.1:5060"); append_branch(); t_relay(); } This failed because the UAC received a "180 Ringing" from the ringing Grandstream phone via ser that contained a To: tag. After the timeout, it received another 180 from Asterisk (the voicemail system) with a different tag. Since it doesn't support forked INVITES, it dropped the call. Then I tried: failure_route [1] { rewritehostport("192.168.1.1:5060"); t_reply( "302", "Moved Temporarily" ); } This time it receives the 180 from the phone as before. Then it receives the 302. Alas, SER has ignored the tag from the phone, and created a new one of it's own, so the UAC again drops the call. Does anyone know of a way round this? Can SER be persuaded to use a tag it has already received? Can I strip the tag from the To: header in one or both of the responses? I'm willing to get my hands dirty with the SER source code if necessary. -- Alistair Cunningham, Integrics Ltd, +44 (0)7870 699 479 http://integrics.com/

[Serusers] No response in serctl add with password heslo

by Che Sosa

I tried adding subscribers using serctl: serctl add che che123 che@localhost It prompts for a MySql password. When I use "heslo", I get NO response. I tried changing the password of admin using: serctl passwrd admin heslo123. This command works with password heslo. What possibly went wrong? These are the config vars in ser_mysql.sh: DBNAME=ser DBHOST=localhost USERNAME=ser DEFAULT_PW=heslo ROUSER=serro RO_PW=47serro11 SQL_USER="root" CMD="mysql -h $DBHOST -u$SQL_USER " DUMP_CMD="mysqldump -h $DBHOST -u$SQL_USER -c -t " BACKUP_CMD="mysqldump -h $DBHOST -u$SQL_USER -c " TABLE_TYPE="TYPE=MyISAM" system info: Linux 2.6.8.1-12mdk #1 Fri Oct 1 12:53:41 CEST 2004 i686 AMD Athlon(TM) XP 1800+ unknown GNU/Linux Using: ser-0.9.0 ser -V output: flags: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.197 2004/12/03 19:09:31 andrei Exp $ main.c compiled on 18:39:55 Apr 6 2005 with gcc 3.4 attached: ser config file

[Serusers] Still no Help -- No ringback for ISDN->SIP->ISDN" using Cisco 2600 Gateway

by karl

Dear all, Following my previous email below, I am still facing the same problem without success of any solution. In this respect, I would very much appreciate whether someone who has come across the same problem in the past and possibly solved it, could at least possible tell me if it was a Cisco IOS issue or a ser configuration issue.

In this, and only in this scenario, the caller doesn't hear any early media (no ringback, no announcements etc).It works like charm when I for example call from a Cisco ATA to ISDN via C5300 and vice versa.When I configure "voice call send-alert" at the C5300, the PROGRESS is converted to ALERT and I hear a ringback tone, but other early media like announcements are also overwritten by a ringback tone.I've also tried "progress_ind setup enable 3", 8 for alert and 8 for proceed, without any success.I've alread studied (hopefully) all available Cisco documentation (voice commands for Firmware 12.2-T, the "Interworking Signaling Enhancements for H.323 and SIP VoIP", the "PSTN Callers not Hearing any Ring Back When they Call IP Phones", "Troubleshooting No Ringback Tone on ISDN-VoIP (H.323) Calls" and so on).Any hints?Regards,AndyPS: I've attached the Q931-debug and here are also the relevant parts of the C5300 configuration:voice call send-alert!voice-port 0:D input gain 2 echo-cancel coverage 32 echo-cancel suppressor timeouts interdigit 3!dial-peer voice 9 pots application session destination-pattern 0. no digit-strip direct-inward-dial port 0:D!dial-peer voice 99 voip destination-pattern [1-9]...T translate-outgoing calling 5 translate-outgoing called 1 voice-class codec 1 session protocol sipv2 session target dns:my.sipserver.com dtmf-relay h245-signal no call fallback no vad!gateway timer receive-rtcp 5!sip-ua retry invite 2 retry response 2 retry bye 2 retry cancel 2-------------- next part --------------A non-text attachment was scrubbed...Name: isndlog_sig.txtType: plain/textSize: 4876 bytesDesc: not availableUrl : https://puck.nether.net/pipermail/cisco-voip/attachments/20040512/48048430/… --------------------------------- Previous message: [cisco-voip] CCM 3.2 and call Parks..

[Serusers] call fwd all with avp_ops question

by Steve Blair

I'm trying to use avp_ops to implement call forward all but it is not working. I'm hoping this list can offer some suggestions. The idea is that a use turns call forward all on or off via the web page. This sets the flag callfwdall to y or n. If flag=y then the user must enter a phone number to which all calls will be forwarded. When a calls arrives for the users phone number callfwdall is checked, if = y then fwdaddr is written to r-uri and the call proceeds through the rest of the route blocks. This is so that any ACL checks can be done on the newly written r-uri so that user cannot forward to an otherwise inaccessible number. Well this isn't working. Here is a snippet from my config. All other calling is working fine. if (method=="INVITE") { if (lookup("location") | lookup("aliases") ) { xlog("L_INFO", "\n[SER]: AVP LOAD: Checking callfwdall flag \n\n"); if (avp_db_load("$ruri/username", "s:callfwdall")) { if (avp_check("s:callfwdall","eq/y/i")) { if (avp_db_load("$ruri/username", "s:fwdaaddr")) { avp_write("$ruri/username", "s:ocn"); avp_pushto("$ruri/username", "s:fwdaaddr"); rewritehostport("net.isc.upenn.edu:5060"); xlog("L_INFO", "\n[SER]: AVP LOAD new ruri: Time: [%Tf] From uri <%fu> To < %tu> Method: <%rm> R-uri: <%ru> Contact Header: <%ct> \n\n"); setflag(3); } else { xlog("L_INFO", "\n[SER]: AVP LOAD: no fwdaaddr \n\n"); }; Thanks,Steve

[Serusers] SER Calls not working with Alias

by Mr Greg Plater

Hi I am having trouble with calls. I have three clients created with alias's asterisk = 38212352, user1 = 38212351 , user2 =38212350 All users can register and I can see with serctl ul show the aliais and the user names. I am using MYSQL and SERWEB also. When I try to call the alias from each user 1 & 2 nothing happens. I think I have to correct something in the route section. I want users to be able to call by alias and calls for PSTN to route to Asterisk with 0 prefix. I start ser with /usr/local/sbin/ser -D -E Can someone please help put my brain to rest. Thank you for all your support. # ------------------------- request routing logic ------------------- # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (msg:len >= max_len ) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol if (!method=="REGISTER") record_route(); # subsequent messages withing a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); break; }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); break; }; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("192.168.1.4", "subscriber")) { www_challenge("192.168.1.4", "0"); break; }; save("location"); break; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; append_hf("P-hint: usrloc applied\r\n"); route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; if (method == "INVITE" && (uri=~"^sip:0")){ rewritehostport ("192.168.1.5:5060"); t_relay(); break(); }
