Hello everyone, My name is Bruno, I'm a student from Portugal studying IMS at the moment. I've been following tutorials online, trying to get Kamailio to work as an IMS core - I'm pretty much a newbie in this field. Unfortunantly I've been getting several errors and I can't seem to properly configure everything. I was wondering if there is a All-in-One VM that can be downloaded, with Kamailio ready to be used as an IMS core? Thanks in advance. Best regards, Bruno C.

Kamailio: MI Command: 'trusted_dump' and 'trusted_reload'

by José Luis Millán

Hi, I'm using 'allow_trusted()' from Permissions module without a problem in a Kamailio 4.0 routing logic. It does just work, but the MI command 'trusted_dump' tells me that the module is not in use: ''' server:/home/jmillan# kamctl fifo trusted_dump 500 Trusted-module not in use ''' Doing a 'trusted_reload' does neither make any query to database to retrieve the data. Other MI commands of same module do work correctly. ie: 'address_reload' or 'address_dump' Note: I have tested in a Kamailio 1.5 and the result is the same. Regards. -- José Luis Millán

Recommendation for toggling MSILO m_store auto-notification reply on/off

by Anthony Messina

Using Kamailio 4.2-dev and MSILO, is it possible to "toggle" the auto- notification reply MESSAGE using something similar to the following where "$var(msilo_reply)" is emtpy at startup (or are there suggestions for a better method): modparam("msilo", "from_address", "$var(msilo_reply)") ... if(CONDITION WHERE I WANT THE AUTO-REPLY RETURNS POSITIVE) { $var(msilo_reply)="$rU(a)example.net"; } m_store($rU) ... My use case is that I would like the auto-notification reply to occur in some instances, but not others. I also do not want to create a loop where the auto-notification replies are also stored. I was originally using a simple test: if(src_ip!=myself), but I have begun to use the IMC module as well as the EXEC module and these MESSAGEs appear to originate from "myself." Looking at the MSILO documentation I see there is "extra_hdrs(string)," but this appears to be designed to add headers to dumped MESSAGEs. I was hoping there would be a way to add a custom header to the auto-notification, on which I could filter/drop generated replies earlier in the route, but it doesn't appear that this exists. My preference for the best-case scenario would be to control the generation of the auto-notification reply in the first place rather than having to add a control to detect the reply and drop it. Thanks in advance for any recommendations. -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

File transferring issue

by Wingsravi R

Dear Kamailio'ns, I am working on kamailio Server (V 4.0) installed on Ubuntu 12.04 system. Currently i am trying file transfer feature using IMSDroid SIP clients. file transferring is fine between two IMSDroid clients but at the receiving end (file recipient) i cont see the sender identity/ sender name. it is just displaying as 'null' (Screen shot is attached). But the full file is transferring to destination address without any problem. I have configured MSRP module related script in my kamailio configuration file (find the attachment). but i guess it is not invoking anyway when file transferring and the file transferring is negotiating client-to-client basis. And also find Sip capture of file transfer (ngrep based) for better understanding. What could be the problem? Why at the file recipient side it is not displaying sender's identity (instead it is 'null')? how can i resolve this issue? Anyone please help me in resolving this issue. Any help will greatly appreciate. Regards, Ravi.

gruu within dialog

by samuel

Hi all, I'm having some issues treating requests within dialogs with gruu enabled with kamailio 4.1.2. I've got the "standard" configuration of WITHIN route with the adition of the next lines: if(is_gruu()){ route(LOCATION); }; before the the RELAY route call in the loose_route section. The "problem" is that the ACK with a pub-gruu on the Req-URI is not properly lookup. In the logs I can see the following statements: 2(4232) DEBUG: registrar [lookup.c:123]: lookup(): looking up pub gruu [urn:uuid:d63b1c4f-d7dc-4f4e-87f1-948123266dc0] 2(4232) DEBUG: registrar [lookup.c:158]: lookup(): 'sam(a)A.B.C.D' Not found in usrloc Where A.B.C.D is the local IP of the UA. Looking at the code, this last line looks like is looking for the "standard" URI (username@domain) instead of using the pub gruu. Am I right with this assumption or am I missing something from the code? As far as I could look, it looks like there's an exit -1 statement in the line 158 of lookup.c which disables the following gruu treatment. Since the username with IP is not registered, this ACK is lost and the sesion is not stablished (lost ACK). Can anyone provide some hints why is this failing? Thanks a lot in advance! Samuel.

Can't start Kamailio with both db_postgres and tls

by Øyvind Kolbu

Hi, I'm trying to add tls to our services, but seem hindered by "something". When enabling the tls module it seems to turn off the SSL setting in postgresql, and since we require SSL on our postgres servers Kamailio can't connect and it fails to start. If I disable WITH_TLS it will start. If I comment out the sqlops modparam it will also start.
