[SR-Users] Can I use Kamailio as B2BUA

[Olle E. Johansson]

I haven't tried this with Kamailio, so please read Daniel's comments.

I did not succeed in using Asterisk to set up multiple TCP connections, but managed to get SIPP to set up one conneciton per dialog. This was during testing the SNMPstats module in Kamailio.
