Re: [SR-Users] uac_req_send() multi-process synchronization problem
by Henning Westerholt 30 Nov '22

30 Nov '22

Hello, not sure if I fully understand the problem. But regarding another user is registered with the same IP address as a previous user, there are several mitigations. To give two options: you could choose a really short re-registration time, you could use TCP and when you lose the connection you delete the contact.

Starting with Kamailio
by Clint Crabtree 29 Nov '22

29 Nov '22

Hello, I’m a DIY entrepreneurial developer beginning to build a system and I stumbled upon Kamailio. I’ve installed asterisk and kamailio in hopes of setting up an IVR to collect voice to speech information from incoming calls. I’m skilled with PHP to Javascript application development. In my research of PBX and discovery of Asterisk I have found enough information online to begin developing with Asterisk ARI; however, somewhere in my discovery process was the suggestion that Kamailio can offer close to real time voice recognition streaming whereas Asterisk is more of a record, pause, translate, respond process. In an AstriCon presentation by Fred Posner I saw recommendations for new applications the suggestion to develop with Kamailio: https://www.youtube.com/watch?v=IaYOboZQEw0?t=23m10s I’m a newbie to SIP, but it seems really promising, can you help point me in the right direction for aforementioned use-case for Kamailio? or am I misunderstanding some if its capability? Regards, Clint Crabtree

Setting package memory from core config
by Alex Balashov 29 Nov '22

29 Nov '22

Hi, There is a way to set the shared memory pool size from core config instead of external CLI arguments: https://www.kamailio.org/wikidocs/cookbooks/5.6.x/core/#shm_mem_size Is there something analogous for package memory (-M)? I could not find it.

db_mysql_new_connection(): driver error: Can't connect to MySQL server
by Denys Pozniak 29 Nov '22

29 Nov '22

Hello! We use Kamailio in conjunction with the cloud Azure Database for MySQL 5.7. It has been noticed that Kamailio does not always start after restarting. It happens to restart a couple of times and everything starts normally. >From the pickup trace I collect on our side, it can be seen that Kamailio connects to MySQL, requests and gets data, and then sends a Request Quit. On another server with a different configuration (slightly different set of modules) and connected to the same database, this issue is not reproduced. How to determine the source of the problem? Below, the logs are filtered by PID of processes in which an error occurred: ERROR: db_mysql [km_my_con.c:163]: db_mysql_new_connection(): driver error: Can't connect to MySQL server on '10.1.128.4'

Turn off transaction accouting but keep dialog cdr accounting?
by Benoit Panizzon 28 Nov '22

28 Nov '22

Hi Team Inserts require resources, especially on high load situations and if there are a couple of indexes on the table. As I use the dialogue module to create CDR, I would like to disable the normal transaction based accounting. I have attempted by not calling: setflag(FLT_ACC) setflag(FLT_ACCFAILED) but I still get both, CDR and Transaction entries created in the corresponding database tables. How could I turn off transaction accounting?

Regex not capturing as required for subst_hf
by Salvinder Parhar 28 Nov '22

28 Nov '22

Hi, I'm trying to capture and substitute the host IP of contact header using the subst_hf but it's not working as expected. I tested my regex in a tester and it works fine there but not in Kamailio config. *Regex:* @(.+?)> *Substitution:* @PUBLIC_IP:5060> *Three contact headers that I'm trying to match;* Contact:<sip:0065*7766@199.48.100.166:5060 >;methods="INVITE,ACK,BYE,CANCEL,OPTIONS,INFO,MESSAGE,SUBSCRIBE,NOTIFY,PRACK,UPDATE,REFER" Contact: <sip:0065*7788@172.16.1.216 ;transport=udp>;expires=3600;reg-id=1;+sip.instance="<urn:uuid:03660bc5-bb70-4784-8ac5-000413B108BA>" Contact: <sip:0925*0007@199.48.100.166:5060> *Outcome I'm expecting for the three contact headers;* Contact:<sip:0065*7766*@PUBLIC_IP:5060>* ;methods="INVITE,ACK,BYE,CANCEL,OPTIONS,INFO,MESSAGE,SUBSCRIBE,NOTIFY,PRACK,UPDATE,REFER" Contact: <sip:0065*7788*@PUBLIC_IP:5060>* ;expires=3600;reg-id=1;+sip.instance="<urn:uuid:03660bc5-bb70-4784-8ac5-000413B108BA>" Contact: <sip:0925*0007*@PUBLIC_IP:5060>* This regex in Kamailio works fine for the first and third contact header but for the second contact header it matches all the way to the end of the contact header excluding the quote (") sign. I've tried so many other combinations [like *(a)(.+?)>;?* ] of regex but nothing seems to work. Is there a way to accomplish this with one regex? Thanks, Sal
