Hi Daniel & K-Team, I setup kamailio 5.0.5 from git on vanilla Debian GNU/Linux 8.3 (jessie) # kamailio -v version: kamailio 5.0.5 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 16:53:42 Jan 5 2018 with gcc 4.9.2 Installed mongodb from debian repo # dpkg -l | grep mongodb ii mongodb 1:3.2.17-1 amd64 object/document-oriented database (metapackage) ii mongodb-clients 1:3.2.17-1 amd64 object/document-oriented database (client apps) ii mongodb-dev 1:2.4.10-5+deb8u1 amd64 object/document-oriented database (development) ii mongodb-server 1:3.2.17-1 amd64 object/document-oriented database (server package) # mongo --version MongoDB shell version: 3.2.17 Will try sometime with mongodb latest version 3.6 as well as I will get time.

Used default kamailio configuration and defined mongodb connection as #!define DBURL "mongodb://localhost/kamailio" I enabled WITH_USRLOCDB [#!define WITH_USRLOCDB], kamailio refuse to start with errors.

I experienced same error when I enable WITH_ACCDB or any other section that use DBURL. 1. Whats the syntax error here? 2. Is there any special configuration required to work with mongodb? 3. How can we create collections using 'kamdbctl create' ? What else should I share for resolving the issue? -- regards, abdul basit On 4 January 2018 at 12:50, Abdul Basit &lt;basit.engg(a)gmail.com&gt; wrote: > Hi Daniel, > > Thank you for your reply. > > I tested libmongoc with debian package available with repo.
