Hi Guys, Hope all are well? We are looking to implement kamailio with cockroachdb due to the advantages it gives us in terms of postgres management and clustering. I can see from a previous string http://sip-router.1086192.n5.nabble.com/CockroachDB-and-Kamailio-td189233.h… that someone has attempted this and even created their own branch. Has any further work been done on this, and if so has anyone got any advice/tips relating to it? As I am nervous about potentially using a branch and not a general release of kamailio moving forwards. I appreciate you cant support all database types but I would just be interested to hear people’s thoughts on the topic. Many thanks!

pipelimit with a kamailio cluster

by Daniel Donoghue

Hello, I have 2 stateful kamailio servers that receive incoming requests, load balanced across the 2 servers by our carrier trunk partners (outside of our control). I am looking at putting certain invites from these trunks into pipelimit to rate limit under some conditions but I have some questions: 1. How will pipelimit establish rates when requests can come in to either of my servers? 2. If pipelimit decides it is time to limit the requests, will both servers respect that limit? 3. does pipelimit rely on a db or can it use dmq, redis or other methods for cross-server communication? 4. Is there a maximum number of pipes that can be defined? Hope somebody can help me answer these questions. With every blessing, — Daniel Donoghue

http_client/http_connect in request_route: INFO: <core> [main.c:857]: sig_usr(): signal 13 received

by Anthony Joseph Messina

With the following config # ----- http_client params ----- modparam("http_client", "httpredirect", 0) modparam("http_client", "connection_timeout", 2) modparam("http_client", "keep_connections", 1) modparam("http_client", "query_result", 0) modparam("http_client", "httpcon", "api=>https://api.example.com"); and after calling the following from request_route, $xavu(http=>rs)=http_connect("api", "/kamailio/message", "application/json", "$var(message_api)", "$xavu(http=>rb)"); if($xavu(http=>rs)==200) { jansson_get("result.code", $xavu(http=>rb), "$xavu(http=>code)"); jansson_get("result.message", $xavu(http=>rb), "$xavu(http=>message)"); sd_journal_print("LOG_DEBUG", "[$cfg(route)] Result: $xavu(http=>code), $xavu(http=>message)"); sl_send_reply("202", "Accepted"); exit; } I see the following in the log: INFO: <core> [main.c:857]: sig_usr(): signal 13 received It doesn't seem to have any negative effect, but I am wondering if it's something I should look into. If so, any pointers on where/how to begin? -- Anthony - https://messinet.com F9B6 560E 68EA 037D 8C3D D1C9 FF31 3BDB D9D8 99B6

Advice on handling SIP trunk to a Perimeta SBC

by Björn Bylander

Hi, So I’m tasked with setting up a SIP trunk to a Perimeta SBC (https://www.metaswitch.com/products/perimeta-sbc). Apparently, > Perimeta hides the topology of networks by rewriting or removing topology-sensitive information from SIP messages. By default, your Session Controller will make the following changes to SIP messages. > > The Session Controller generates new dialog identifiers (call-IDs, From tags and To tags) for each side of the call, so that it does not expose information about your core network to your access networks. > The Session Controller strips Record-Route and Route information from the message. > The Session Controller rewrites Contact and Via headers so that the source IP address is replaced with the local address of the outbound adjacency. > The Session Controller replaces the IP addresses in c= lines in SDP with the addresses it has allocated for media forwarding. For more information on this, see Media addresses and gates. My problem is this: When the Perimeta SBC sends its first INVITE (I can't say anything about any succeeding INVITEs yet) it's added a Record-Route header with the "lr" parameter included which, as far as I can see makes Kamailio think it should use loose routing which is all well I think. But when the SBC sends an ACK for the "200 OK" from the Kamailio side it doesn't include any Route headers and I think that makes it hard for Kamailio (at least with the standard script which is basically what I'm using) to know where to relay the ACK, at least it makes the t_check_trans() call in WITHINDLG after 'is_method("ACK")' return false which makes the script ignore the ACK. Any thoughts or suggestions on how to handle this? Thanks in advance, Björn Bylander

Usage of ldap/db2_ldap

by DEV

Hi! I'm trying to use the ldap / db2_ldap module in kamailio but I'm stuck because the docs seem to either be outdated or me being on the wrong track. >From what I understand, I need a single ldap.conf but there are two example files with different syntax: 1) https://github.com/kamailio/kamailio/blob/master/src/modules/db2_ldap/ldap.… 2) https://github.com/kamailio/kamailio/blob/master/src/modules/ldap/etc/ldap.… I'm already using ldap realtime for asterisk and want to switch kamailio to use the same objects by using this schema: https://github.com/kamailio/kamailio/blob/master/src/modules/db2_ldap/ser.s… When using syntax from (1) I receive this error: ERROR: ldap [ldap_mod.c:198]: mod_init(): no section found in config_file [/etc/kamailio/ldap.cfg] I double-checked my conf and it matches (1). When using (2), I got an error, telling me I left some tables unconfigured (even when mixing both syntax). What is the correct syntax to use ldap as my auth module and replace mysql auth tables? Thank you. Kind regards Kevin

Indeed I tried to configure it to use remote Postgresql and failed, so I came back to MYSQL as it looks somekind of default config. To Kamailio. Thank you in advance.

Re: [SR-Users] Advice on handling SIP trunk to a Perimeta SBC

by Björn Bylander

Hi again, I'm using Kamailio 5.3.2 by the way. Björn Bylander writes: > Hi, > > So I’m tasked with setting up a SIP trunk to a Perimeta SBC (https://www.metaswitch.com/products/perimeta-sbc). > > Apparently, > > Perimeta hides the topology of networks by rewriting or removing topology-sensitive information from SIP messages.

For more information on this, see Media addresses and gates. > > My problem is this: When the Perimeta SBC sends its first INVITE (I can't say anything about any succeeding INVITEs yet) it's added a Record-Route header with the "lr" parameter included which, as far as I can see makes Kamailio think it should use loose routing which is all well I think. But when the SBC sends an ACK for the "200 OK" from the Kamailio side it doesn't include any Route headers and I think that makes it hard for Kamailio (at least with the standard script which is basically what I'm using) to know where to relay the ACK, at least it makes the t_check_trans() call in WITHINDLG after 'is_method("ACK")' return false which makes the script ignore the ACK. > > Any thoughts or suggestions on how to handle this? > > Thanks in advance, > Björn Bylander
