Hello,
working on Kamailio SCSCF module, when I receive an INVITE the serving
module should find the corresponding ICSCF to forward the INVITE. In
order to do this it should perform a NAPTR query, followed by a DNS
SRV query and a DNS A query.
In our case the serving has the following behavior:
1) it CORRECTLY make NAPTR query
2) it send an SRV query to resolve ICSCF service port having invalid
response 4 times.
After 4 times, so 20 seconds, it sends INVITE message to ICSCF at
default port 5060.
SRV query contains a null name, shown as <Root> in Wireshark. Current
DNS application (MyDNS) answer with a not implemented response.
I expect that the serving CSCF try to resolve the ICSCF making an SRV
query and an A query to discover the service port and ip address using
the domain returned by NAPTR query.
I have two questions:
It seems that SRV query is not valid, because it's not based on SIP
domain, do you think it's correct?
At least, is it possible to configure s-cscf to force an INVITE to be
sent always to the same interrogating?

Hi,
I am using LCR module to send outbound calls to my carrier, however I am
using a new carrier who require authentication. Any ideas on how to
authenticate the call to the carrier?
Thanks

Dear list,
I'm having an issue with our Kamailio setup.
I've installed two Kamailio servers with Corosync/Pacemaker. Kamailio1 has ip 10.254.254.5, Kamailio2 has ip 10.254.254.23. The VIP is 10.254.254.1. All is working well; clients can sent request to the VIP, and all traffic is sent via 10.254.254.1, and not the real ipI've configured the listen addressess:
mhomed = no
listen = udp:10.254.254.1:5060
listen = udp:10.254.254.23:5060
I'm now trying to configure the server as a multihomed one. Both Kamailio have two NIC's. Kamailio1 also has ip X1, Kamailio2 has ip X2. The VIP is Y. Configuration is done as:
mhomed = yes
listen = udp:10.254.254.1:5060
listen = udp:10.254.254.23:5060
listen = udp:Y:5060
listen = udp:X1:5060
When a UA sends an INVITE to for example 10.254.254.1, all responses (back) to UA are being sent with source address 10.254.254.1 (VIP), except for the ACK (and BYE). The ACK is sent via the real ip 10.254.254.23. I can resolve this by issuing a force_send_socket before t_relay in the config; but since it's multihomed, I have to build a lot of checks to find out the outgoing socket. Besides that, I want it to be possible to use both the real IP and the VIP as IP-address for the UA (for testing purposes). This won't work with force_send_socket.
Does anyone from the list know how I can solve this?
Thanks,

Hello all,
I want to know the difference between kamailio-3.1.1
and kamailio-4.0 in regard to their features. If anyone has the experience to use both. What improvements will one enjoy on upgrading to kamailio-4.0 as compared to kamailio-3.1.1. I asked this question and a friend suggested some webpages. They give updates in modules for every version from 3.1 to 4.0. That is good but I want to know in short what main improvements will I get. Thanks for help.
Cheers,

Hi All,
I know there are some products out there but I'm looking for a very basic
way to store in a database the SIP call journey including errors etc.
Anyone have any ideas?
Thanks,
Keith
Thanks for the info guys, unfortunately it's not sending the from ip
address properly now. I am using dispatcher to route these calls so not
sure if the $fs is working properly?
Any more ideas?
Thanks
Keith
Hello all,
I want to know the difference between kamailio-3.1.1 and kamailio-4.0. As I am running kamailio-3.1.1 in my environment. I am interested to know what improvements will I enjoy if I reset the whole system and use kamailio-4.0(latest stable version). Replacing is quite a huge task, I have to make a decision whether it is worth it or not. Can some one please suggest any online page to read which can help. Any help will be much appreciated. Thanking in advance.

Owais ul Haq,
