Hi,

you can definitely do this with Kamailio. We've made a similar setup at an MNO, where we had two EPCs and two IMS-Cores which were directly interconnected (using an Oracle/AcmePacket SBC or directly).

Thanks, Carsten

Hello,

Is SIP trunking possible with the free version of Kamailio or we need to upgrade to business license?

There is only one version, the free business version :-)

Kindly get back to us with the details of using SIP trunking using Kamailio. We have a requirement in our organisation regarding the same which uses IMS and SIP trunking.

Kamailio supports SIP trunking, but the definition of SIP trunking varies :-)

...

In this setup we would initially like to test with 2 LTE EPCs connected to two Kamailio IMS with a SIP trunk between them.

There are some IMS modules you can look into for this and consultants focused on LTE/IMS deployments with Kamailio, check the web site for names and addresses.

Best regards, /Olle
