Alex, I get the following error ERROR: <core> [core/pvapi.c:1127]: pv_parse_spec2(): wrong char [ ERROR: bad config file (1 errors) CRITICAL: <core> [core/cfg.y:3537]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 462, column 23-40: Can't get from cache: $(rU{s.select,0,#) David, I did try escaping and get the same error. $avp(techprefix) = $(rU{s.select,0,\#}); additionally, I think I initially tried it double quoted. $avp(techprefix) = $(rU{s.select,0,"#"}); Resulted in: ERROR: <core> [core/pvapi.c:1127]: pv_parse_spec2(): wrong char [ ERROR: bad config file (1 errors) CRITICAL: <core> [core/cfg.y:3537]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 462, column 23-42: Can't get from cache: $(rU{s.select,0,"#") Here is the entire block. if ($rU =~ "[\*\#]") { xlog("L_INFO", "[$ci] -> $rU appears to have a tech prefix, processing...\n"); if ($rU =~ "\*") { $avp(techprefix) = $(rU{s.select,0,*}); ## Reset the RURI user to the non-tech prefix'ed value $rU = $(rU{s.select,1,*}); ## Overwrite the message source variable with "sourceip-techprefix" $var(messagesource) = $_s($si-$avp(techprefix)); } else if ($rU =~ "\#") { $avp(techprefix) = $(rU{s.select,0,#)}); ## Reset the RURI user to the non-tech prefix'ed value $rU = $(rU{s.select,1,#}); ## Overwrite the message source variable with "sourceip-techprefix" $var(messagesource) = $_s($si-$avp(techprefix)); } } On Sat, Jan 11, 2020 at 5:00 AM <sr-users-request(a)lists.kamailio.org> wrote: > Send sr-users mailing list submissions to > sr-users(a)lists.kamailio.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users > or, via email, send a message with subject or body 'help' to > sr-users-request(a)lists.kamailio.org > > You can reach the person managing the list at > sr-users-owner(a)lists.kamailio.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of sr-users digest..." > Today's Topics: > > 1.

Trigger a custom SIP Notify Message on demand
by Rupesh Kumar 14 Jan '20

14 Jan '20

Hello kamailio gurus, I was wondering if there is a way to send a custom SIP NOTIFY message from kamailio to the registered SIP clients on-demand. For example, I want to take a kamailio node for maintainance and want all polycom phones registered on a kamailio node to re-register and move to a different kamailio node. I know the uac module can send custom requests via uac_req_send, but can I invoke this via a kamcmd or kamctl command ?Any pointers/clues would be a great help. Thanks,RK

topos and db_redis
by Ben Merrills 13 Jan '20

13 Jan '20

Hi All, Quick question, I've tried to find this myself, but there doesn't seem to be any documentation that I can find on it. Does the topos module work with db_redis module? I can see two schema files for topos (topos_t, topos_d), but I can't work out what the keys should be. modparam("db_redis", "keys", "topos_t=entry:hash_entry,hash_id,...?") modparam("db_redis", "keys", "topos_d=entry:hash_entry,hash_id,...?") modparam("topos", "db_url", "redis://127.0.0.1:6379/kamailio") modparam("topos", "storage", "db") Any pointers would be greatly appreciated. Kind Regards, Ben Merrills

Diameter EVENT_REQUEST
by Steve Bucklin 13 Jan '20

13 Jan '20

Dear All, I was wondering if someone could give me a pointer on handling diameter "EVENT REQUEST" (416) I am a complete newb to the diameter, and have used a RESTCOMM SMS-C to generate charging requests. 1. I have got the CDP and other modules going and it connects with application (Diameter Credit Control Application (4) 2. I tried to use a simple ims_ocs module, but get a "getMethod()" error. Looking at the code, there are only three supported, START, INTERIM, & STOP. 3. I have captured the message in pcap - and all looks OK. 4. To examine the whole message I tried using the ims_diameter_server module to produce a JSON of all the values sent in the $diameter_request within the event_route, HOWEVER once the request arrives I get an error: ERROR: cdp [diameter_avp.c:645]: AAAUngroupAVPS(): hss3g_ungroup_avps: source buffer to short!! Cannot read the whole AVP header! I assume that the cdp function AAAUngroupAVPS() cannot sort the data into JSON due to a buffer issue. Any pointers? Steve

String Transformation Question
by Sam Ware 10 Jan '20

10 Jan '20

We are receiving traffic with a tech prefix. We want to be able to use a # (hash tag) for the separator for the tech prefix and the remote user ($rU). I was using the s.select transformation before when using * for separator, but I get an error because it appears that it being interpreted as a comment. Any suggestions? Example: ## How I was doing it with the * $avp(techprefix) = $(rU{s.select,0,*}); ## How I tried and got an error for the hash tag $avp(techprefix) = $(rU{s.select,0,#}); -- Sam D Ware

caching 404 responses
by Krzysztof Drewicz 10 Jan '20

10 Jan '20

Hello would like to see if I'm not reinventing the wheel: scenario: some old powerdialler/predictive calls kamailio as call dispatcher, kamailio then dials carrier. But this dialler does many calls to the same B number with 404 response (from carrier) in short (retry is < 600s) time, so no need to bother PSTN/carrier with retry. Should I simply use htable, cache 404 hit, use some reasonable value modparam("htable", "db_expires", 1) put there like 600 s TTL or something like that? Any hints/thoughts? Maybe this scenario is common and being used with success somewhere (and yes, this powerdialer is not very clever, and I do know it should not be needed for this) Thanks, -- *Krzysztof Drewicz* Senior Infrastructure Administrator CLUDO | ul.
