It gets the traffic over a raw socket and then executes the config file as usual with functions from other modules?

Question on ("sipcapture", "raw_interface", "")

by Nelson Pereira

Is it possible to monitor 2 interfaces? I have 2 Asterisk servers and they are on 2 different switches so I need to capture ETH0 and ETH3 which is where the mirror ports are connected to from each switch. Thanks

CAcert root in Lumicall

by Daniel Pocock

I've been contemplating Daniel's earlier question about using the CAcert certificates with Lumicall sip5060.net should already accept mutual authentication from other Kamailio instances running with a CAcert certificate However, the Lumicall dialer itself will only connect to servers that are using a cert signed by a root CA trusted within Android. This applies to both the SIP and STUN over TLS support. It may be possible for me to embed the CACert root in the Lumicall package and create a custom trust manager - allowing Lumicall to work with any server using CAcert TLS certificates. Does anyone have any strong feelings about not doing something like that?

how to match exact string value in mtree

by Uri Shacked

Hi, I am using Mtree to match prefix numbers, some of them starts with 0 or characters like D for example. so, the mtree param is like this: modparam("mtree", "db_url", CFGDB) modparam("mtree", "mtree", "name=nts;dbtable=service_numbers_view;type=0;") modpmodparam("mtree", "char_list", "0123456789*+#YMDabcdefgh") modparam("mtree", "pv_value", "$avp(mtval)") modparam("mtree", "pv_values", "$avp(mtvals)") The thing is, that i tried all: if(!mt_match("nts", "$avp(DID)","1")) if(!mt_match("nts", "$avp(DID)","2")) if(!mt_match("nts", "$avp(DID)","0")) and lets say i have the both prefix in the nts mtree: 09555 09555333 And the prefix i search for is $avp(DID)=09555444 I allwasy get the 09555 because it is the longest match. I need exact match..... how do i do that?

How to do request URI rewrites using database tables?

by Ben WIlliams

Hi, can someone please recommend the most appropriate modules to rewrite R-URIs based on a database lookup table? I've read the documentation for lcr and carrierroute but not sure if they can do this. In most cases it will be a simple R-URI rewrite but I also need to rewrite based on From user. ie R-URI match From match new R-URI =========== ========== ========= *97(a)example.com 6[0-9](a)example.com *97(a)10.0.0.1 *97(a)example.com 7[0-9](a)example.com *97(a)10.0.0.2 6[0-9](a)example.com match any rewrite domain to 10.0.0.1 abc(a)example.com match any def(a)example.com Thanks Ben

Problems with TCP

by Mino Haluz

Hi, our customers are using mostly UDP but some of them want to use TCP. The problem is, I get various TCP errors in kamailio log and I do not understand what they mean 1) ERROR: <core> [tcp_main.c:4130]: connect <customerIP:port> failed This means kamailio is trying to connect with TCP to the customer ?? 2) WARNING: tcp_do_connect <customerIP:port> : could not find corresponding listening socket for IPaddress , using default... ( where IPaddress is kamailio physical IP address) Kamailio has one virtual IP address (heartbeat IP address) and one physical. It listens on the virtual IP address but I do not understand why it is trying to use the physical IP address ? I was investigating this thing because the BYE message is not being relayed if the TCP is used (everytime the 2. error message is printed), so that's why I have to understand what it really means... And the last question, 3) If kamailio is relaying the traffic to the PSTN gateway, and the customer is using TCP, kamailio uses TCP as well for connecting to the PSTN gw. Is this behaviour normal ? I would expect that customer -- TCP --> kamailio --- UDP --> GW, and not customer -- TCP --> kamailio --- TCP --> GW, Thanks, Mino
