trigger different branch route on branch added with append_branch
by Benoit Panizzon 18 Jan '24

18 Jan '24

Hi List Imagine the following situation: Two Kamailio registrar proxies handling the same domain. Location Information synced via DMQ. So if a device registers we don't know on which of the two registrar proxies. Core proxy is dispatching calls to either one of those registrars. Core also performs AOR database lookup and adds an X- header telling which AOR the call is destined to. Registrar performs lookup of that AOR in the location database and routes the call to destination. Problem: The call could be routed to the the registrar which does not hold the active socket to that client. Solution: reg_fetch_contacts, cycle the contacts and append_branch if the contact has a local socket. Next Problem: I use a failure_route to sent the call to voicemail, if not registered, busy etc. This would trigger, if we have no local socket for the registration which is on the other registrar. So I have to find a way to send the call to the other registrar. I guess I can append_branch a branch pointing to the URI of the other registrar. This would then succeed in reaching the device. Also using the failure_route would work this way if we get a remote error from behind the other registrar or no registration at all. Next Problem: I use a branch trigger to remove undesired header I do not want to send to the customer. Now imagine that AOR has two contacts, one on registered on each registrar proxy. So I end up with two destinations added with append_branch to the destination set. One points to the device of the locally registered customer device, the other one points to the other registrar where to find the other device. I use a branch route trigger to remove the X- Headers towards the customer. But I need to X- Header containing the destination AOR to still be sent to the other registrar. Is there a way to trigger a branch route for only some of the destinations added with append_branch? Or to trigger different branch routes for different destinations in one set added with append_branch? Or am I doing this completely wrong and there is an easier way? ;-) Mit freundlichen Grüssen -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

add a SIP custom header on a SIP response generated locally
by frédéric Gaisnon 18 Jan '24

18 Jan '24

Hello, I want to add a SIP custom header on a SIP response generated locally (on the 408 generated when fr_inv_timeout is expired for example) I've tried functions append_hf and append_to_reply in event_route[tm:branch-failure:XXX] or event_route [tm:local-response] without any success. Do you have any suggestions to accomplish this ? Regards, Frédéric Gaisnon

tls.cfg and configuration
by Aymeric Moizard 17 Jan '24

17 Jan '24

Hi all, I'm using a central file to define my kamailio cfg configuration. First question: In my main kamailio.cfg, I use: include_file "kamailio-config.cfg" which contains: #!substdef "!MY_DOMAIN!kamailio.example.com!g" I would like to use the same in tls.cfg which is defined this way: modparam("tls", "config", "/etc/kamailio/tls.cfg") but I get: sr_cfg_parse(): tls.cfg:17:1: Unsupported option 'include_file' Would you advise some way to achieve my goal: ie, I would like only one file to edit my configuration options which would have an effect on both kamailio.cfg and tls.cfg Second question: Can someone confirm that #!substdef will also not have any effect when used in tls.cfg Thanks Aymeric -- Antisip - http://www.antisip.com

Not checking SRV records
by Jon Bonilla (Manwe) 13 Jan '24

13 Jan '24

Hi This may be a stupid question but after a couple of hours and some headache I can't see where the problem is. I'm trying to use SRV records to relay to different servers as I've done many many times before. But in this case I'm getting a 478 from kamailio and I see that it's not trying to resolve SRV. From the log: [core/dns_cache.c:527]: _dns_hash_find(): (fs.mydomain.dev(16), 1), h=632 [core/resolve.c:784]: get_record(): lookup(fs.mydomain.dev, 1) failed [core/dns_cache.c:761]: dns_cache_mk_bad_entry(): (fs.mydomain.dev, 1, 60, 1) [core/dns_cache.c:701]: dns_cache_add(): adding fs.mydomain.dev(16) 1 (flags=1) at 632 [core/dns_cache.c:2807]: dns_a_resolve(): (fs.mydomain.dev, 0) returning -7 [core/dns_cache.c:3176]: dns_srv_sip_resolve(): (fs.mydomain.dev, 0, 0), ip, ret=-7 uri2dst2(): failed to resolve "fs.mydomain.dev" :unresolvable A or AAAA request (-7) When doing tcpdump port 53 I see A record query but no SRV SRV records of course exist although they are not being checked. dns params in kamailio: dns_try_ipv6=no dns_retr_time=1 dns_retr_no=1 dns_use_search_list=no use_dns_cache=on use_dns_failover=on dns_srv_lb=on dns_try_naptr=no dns_sctp_pref=1 dns_tcp_pref=1 dns_tls_pref=1 dns_udp_pref=1 Same exact config in another server is working. There's something I'm missing and can't see. Any hints? cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

Hello. I have some rant with network security dept. Is there some standard, RFC, what port range should be used for RTP traffic, how RTP ports are selected during SIP call negotiation? Thanks.
