Have you listed the profile via kamctl or kamcmd? The commands are in the readme: http://kamailio.org/docs/modules/stable/modules/dialog.html#idp3737432 Is the afferent profile listing any dialog?

I don't know what exactly happened in your case but if you don't have time to investigate you can try cnxcc module [1] channel control to achieve the same goal. Take a look at the sample configuration file located in [2] xlog("L_INFO", "Setting up channel based credit control"); $var(max_chan) = 2; $var(retcode) = cnxcc_set_max_channels("$var(client)", "$var(max_chan)"); if ($var(retcode) == -1) { xlog("Error setting up credit control"); return; } $var(count) = -1; … [View More] if (!cnxcc_get_channel_count("$var(client)", "$var(count)")) { xlog("Error getting customer's channel count"); } xlog("L_INFO", "CNXCC ROUTE: $var(client) has $var(count) call(s)"); if ($var(retcode) < -1) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden"); if (!cnxcc_terminate_all("$var(client)")) { xlog("Error terminating customer's calls"); } exit; } [1] http://kamailio.org/docs/modules/devel/modules/cnxcc.html [2] https://github.com/caruizdiaz/cnxcc/blob/master/example/kamailio-cnxcc.cfg Regards, Carlos On Fri, Aug 23, 2013 at 5:16 AM, Gertjan Wolzak <g.wolzak(a)foize.com> wrote: > ** ** > > Goodmorning All,**** > > ** ** > > I use the following route to check for concurrent calls by the same user, > if a concurrent call is tried it is not allowed.**** > > ** ** > > route[CONCURRENT]**** > > {**** > > xlog("SCRIPT: Conccurrent call check");**** > > ** ** > > if(!get_profile_size("caller","$fu","$avp(nrcalls)"))**** > > {**** > > sl_send_reply("403", "Call not matching profile");**** > > exit;**** > > }**** > > xlog("SCRIPT: caller value for $fu is $avp(nrcalls)");**** > > if($avp(nrcalls)>= 1)**** > > {**** > > sl_send_reply("403", "Active calls limit exceeded");**** > > exit;**** > > }**** > > dlg_manage();**** > > if(!set_dlg_profile("caller","$fu"))**** > > {**** > > sl_send_reply("500", "No new channels in this profile");** > ** > > exit;**** > > }**** > > ** ** > > xlog("SCRIPT: caller value for $fu is now $avp(nrcalls)");**** > > ** ** > > }**** > > ** ** > > Now I had a situation where a user could not call because the > get_profile_size for this user gave the value 1.

mediaproxy-ng one-way audio (but not all the time)
by Peter Dunkley 23 Aug '13

23 Aug '13

Hello, I am testing mediaproxy-ng (running on CentOS 6 on Amazon EC2) for WebRTC to non-WebRTC calls and I am getting one-way audio most (but not all) of the time. I always get audio in the WebRTC to non-WebRTC direction. Has anybody had any experience of anything this? I have checked the obvious (all the ports open in iptables and the Amazon security groups). I know that the right (advertised) address is going into the SDP. I am getting an error message out of mediaproxy-ng a lot. But … [View More]

Goodmorning All, I use the following route to check for concurrent calls by the same user, if a concurrent call is tried it is not allowed. route[CONCURRENT] { xlog("SCRIPT: Conccurrent call check"); if(!get_profile_size("caller","$fu","$avp(nrcalls)")) { sl_send_reply("403", "Call not matching profile"); exit; } xlog("SCRIPT: caller value for $fu is $avp(nrcalls)"); if($avp(nrcalls)>= 1) … [View More]

Re: [SR-Users] Subscribe to a common resource list
by Yufei Tao 23 Aug '13

23 Aug '13

Now I've got round this by calling rls_handle_subscribe($tu), if $tu is detected as a group uri. So $tu will be used as watcher_username to compare with the RL's user. Seems to work but not sure if this is the right way, i.e. is there a way of putting the group's RL under a special URL so that every other user can get its RL document?

AVPops clarification
by Daniel W. Graham 22 Aug '13

I am using avp_db_load to read certain values from usr_preferences table. Since sqlops is more efficient / preferred over avp_db_query, I was wondering if this would also apply to avp_db_load ? -dan

DB_CLUSTER - Cluster Definition
by Charles Chance 22 Aug '13

22 Aug '13

Hi All, I'm having difficulties with the above module and can't see what I'm doing wrong. Config as follows: modparam("db_cluster", "connection", "db01=>mysql:// > readwrite:password@db01.domain.com/kamailio") > modparam("db_cluster", "connection", "db02=>mysql:// > readonly:password@db02.domain.com/kamailio") > modparam("db_cluster", "cluster", "cls1=>db01=0s9s;db02=9s0s") As you can see, there are two database servers - a master and a slave. I am trying to force all … [View More]

UAC remote registrations caller id
by Isaac McDonald 22 Aug '13

22 Aug '13

Hello, I'm using the UAC module to perform remote registrations. When an incoming call comes in from one of the remote registrations I'm using the following to route the call to the correct user: if(uac_reg_lookup("$rU", "$ru")) { lookup("location"); route(RELAY); } This works fine for routing the call to the local user but the "from domain" still contains the IP address of the remote registrar. This results in the caller ID being displayed along with the … [View More]
