Hi All,

I am planning to use Kamailio, to build a B2BUA with the following functionalities:

-          Topology Hiding (SIP: To, From, Call-ID, P-Asserted-ID)

-          Topology Hiding (SDP: Changing SDP info - and act as an RTP Proxy)

-          Perform - NAPTR ENUM Query

-          To Release call (If Max Duration Reached)

-          Generate CDRs.
[Note: This is somewhat like a light SBC service]

Now, my question is how to develop this service over Kamailio.
Does Kamailio provide any Development APIs, which this B2BUA can use?
OR I need to enhance or built new Kamailio modules?

>From the initial understanding, I got to know, Kamailio maintains SIP Transactions, and NOT the SIP Dialog, and basically I need to build this.

It will be great if someone can give me any leads on this front.
