Everything is fine until it gets to line 573, where it calls fifo_find_domain, which sets d=0. Then, in line 575, the error message given above is returned because d if now false. static inline void fifo_find_domain(str* _name, udomain_t** _d) { dlist_t* ptr; ptr = root; while(ptr) { if ((ptr->name.len == _name->len) && !memcmp(ptr->name.s, _name->s, _name->len)) { break; } ptr = ptr->next; } if (ptr) { *_d = ptr->d; } else { *_d = 0; } } I'm not a C programmer, so I don't really understand what's happening here, but it appears to be looping through a list to find a domain, checking to be sure their lengths and values match. It keeps looping until it finds one, and then quits on the first one. It appears that ptr doesn't point to anything in my case; it fails the next if, setting the passed-by-reference d to 0, leading me to think that it hasn't found any domains, or couldn't get a domain list in the beginning. What does this "ptr = root;" mean? I then tried running `openserctl domain show`, only to get: 500 command 'domain_dump' not available Now, I checked the actual database openser.domain table, and my domain appeared correctly. I am also loading the domain module on openser startup. Any ideas? I realize this is getting awfully deep into code, but I hope someone can help. It's probably a simple error on my part. Thanks in advance. Mike Williams

[Users] LCR module
by Ovidiu Sas 10 Jan '06

10 Jan '06

Hi all, The new lcr module has now two modes of operation controlled by the direct_db parameter: - direct_db = 1 (no DB caching) This is the old behavior of the lcr module - direct_db = 0 (DB caching - default one) In this mode, the 1.7 TODO issue from the README file is addressed: no more SQL query in load_gws() function. In addition to this, the From URI from the lcr table is now a POSIX regular expression, with the following extension: if the From URI is an empty string, it will be considered as a universal match - ie .* without invoking the regexec function. Migrating from the old mode to the new mode requires the from_uri column from the lcr table to be updated to use POSIX regular expressions instead of the special _ and % characters. Example: old from_uri -> new from_uri ------------------------------ % -> 123% -> 123.* regards Ovidiu Sas

[Users] TLS problem
by David 10 Jan '06

10 Jan '06

Hello. I'm trying to use TLS with openser. I've made the steps from the tutorial:http://openser.org/docs/tls.html. I have "tls_verify = 1" and "tls_require_certificate = 1". I have a phone without TLS support, but it registers in openser. I think, this shouldn't happend. Anybody has ideas? Second question: I used netstat to verify if somebody is listening on 5060 and 5061, but if I put ip_openser:5061 in the phone, I have an icmp message with "destination unreachable". What's happening? Thanks

[Users] LCR problem

Hello, Im making tests and its not a LCR problem, its a problem from my GW2, when I use it for first option, it fails too, here you have the ngrep, ClientA --> Proxy --> GW2 (192.168.10.93) (192.168.10.91) (195.219.74.166) Regards The problem is that the BYE request will be handled by your LCR logic. The BYE request should be route in the loose_route block as it is an in-dialog request. Maybe the BYE sent from the gateway is not correct. Please post a ngrep dump (ngrep -t -W byline port 5060) regards klaus Pepe wrote: > Hello, > > Im configuring Openser with LCR module and Im having an extrange > behavior, I have 2 gateways, GW1(preference1) and GW2(preference2), > > GW1(pref.1) > / \ > ClientA --> OpenSer --> Client B > \ GW2 (pref.2) / > > > When I call from Client A to Client B using GW1, all works fine, its the > same when hang up Client B or Client A, but when GW1 fail(I provoke it > changing codec) and use failure route (GW 2) then if Client A hang up > all works fine, but the problem is when is Client B who hang up, its > like a new conversation, GW 2 send BYE to openser and Openser just send > "503 Service Not avilable - No gateways" to GW2, but doesnt send nothing > to ClientA, any idea ???? > > > Thx in advance >

[Users] problem accounting of ACKs
by Klaus Darilion 09 Jan '06

09 Jan '06

Hi! I have problems accounting ACK (e2e ACKs after INVITE-200 Ok). I have the following setup: client1 proxy1 proxy2 proxy3 client2 |---INVITE--->| | | | | rewritehostport | | | | t_relay | | | | |--INVITE->| | | | | enum_lookup | | | | t_relay | | | | |-INVITE-->| | | | | lookup() | | | | t_relay | | | | |-----INVITE->| | | | | | | | | |<----200 OK--| | | |<--200 OK-| | | |<--200 OK-| | | | <--200 OK---| | | | | | | | | | ---ACK----> | | | | | loose_route | | | | |----ACK-> | | | | | loose_route | | | | |---ACK--->| | | | | loose_route | | | | |---ACK------>| | | | | | All proxies do accounting. I do see the INVITE and BYE requests accountend by all proxies, but the ACK is only accounted by proxy1. All proxies are configured nearly identical: # accounting parameters modparam("acc", "early_media", 1) modparam("acc", "report_ack", 1) modparam("acc", "report_cancels", 0) modparam("acc", "multi_leg_enabled", 0) modparam("acc", "failed_transaction_flag", 4) # radius, syslog and DB modparam("acc", "log_flag", 1) # syslog modparam("acc", "db_flag", 2) # DB modparam("acc", "db_missed_flag", 3) # DB missed calles table modparam("acc", "swap_direction", 1) and all the flags are set for sure: route{ setflag(1);setflag(2); setflag(3);setflag(4); Does somebody had a similar problem? Are there any known issues how ACKs are handled? Studying the debug log. it looks like proxy 1 identifies the ACK as belonging to a transaction, whereas proxy 2 does not find the transaction (full debug at the end of the mail): proxy 1: ----------- t_lookup_request: start searching: hash=6242, isACK=1 parse_headers: flags=38 DEBUG: t_lookup_request: e2e proxy ACK found parse_headers: flags=8 DEBUG: totag for e2e ACK found: 0 DBG: trans=0x406b1940, callback type 4, id 0 entered parse_headers: flags=258 ACC: request acknowledged: method=ACK, i-uri=sip:user201@..... proxy 2: ----------- t_lookup_request: start searching: hash=6242, isACK=1 DEBUG: proceeding to pre-RFC3261 transaction matching DEBUG: t_lookup_request: no transaction found DEBUG:tm:t_relay: forwarding ACK statelessly DEBUG: mk_proxy: doing DNS lookup... parse_headers: flags=1000 check_via_address(10.10.0.41, 10.10.0.41, 0) Sending: ACK sip:user201@10.10.1.50:8737 SIP/2.0^M To: <sip:+43201@proxy1 Thus, why is there a matching transaction in proxy 1, but not in proxy 2?

Bogdan-Andrei Iancu,hello Ask for you again. :) I am succesful on openser for TLS connected by SIPp,but not minisip :( thanks for your more help! Now I step to srtp! Can I use SRTP to build peer to peer communication from openser? if outbound via openser.or do you learn more about srtp of SIP. Best Regard! Kenny from China Shanghai 2006-1-5

Re: [Users] snom registration expiry
by Christian Benke 09 Jan '06

09 Jan '06

Hello Klaus! Thanks for your reply, you have triggered some new ideas. of course i should have thought about checking back if any packets are received by the openser host after the line is dead but i thought if it still works with ser, it should work with openser too(and i still have no problems with a second line registered at ser@port5060 while the registration at openser@5061 is lost). ok, the result of the ngrep was that no packets appear on the openser-host when i try to call from the (dead) line. i've made some tracing both on the snom and the ser/openser-host as you suggested. To my surprise, the snom seems to be the device that doesn't behave as expected - it doesn't re-register on the openser-configuration! I have made the attached traces in this way: First i've set the account-details on the snom with 103456(a)sip.de.domain.cc,then rebooted the phone and started the trace on the siprouter-host on port 5060(ser), then changed the configuration to 112233(a)siptest1.domain.cc, rebooted the phone and made the second trace on port 5061(openser). In both cases i didn't touch the phone or make any calls after the reboot to get a pure registration-trace. When i use the account 112233(a)siptest1.domain.cc, the snom registers once and doesn't try to re-register anymore. With the account 103456(a)sip.de.domain.cc, the snom re-registers every 5 minutes, not the expected 10 minutes, but at least it does re-register. When switching the account-details, i didn't do anything but changing the login-details(username, password, registrar-url), the rest of the configuration has not been touched. The phone-firmware is 3.60w. There doesn't seem to be a difference between the siplogs, at least i can't see it. i'm really puzzled right now... 8-| I've attached the siptrace from the ser/openser-host: SER_host_siptrace.txt/OPENSER_host_siptrace.txt the syslog from snom190: SER_snom190_log.txt/OPENSER_snom190_log.txt and the siptrace from snom190: SER_snom_siptrace.txt/OPENSER_snom190_siptrace.txt I have tried this several times now, changing the configuration and rebooting, same results everytime. on SER it's reregistering exactly every 5 minutes, on OPENSER it isn't. I hope all this information is not too much and you have the time to sniff through. thanks! christian p.s.:i've also thought about a error in the srv-records on my nameservers, but they look exactly the same for all sub-domains, the only difference is the port change from 5060 to 5061...
