[SR-Users] Architecture - your opinion is welcome and your experience too

[Alex Balashov]

Hi Daian,

Rather than reoriginaring registrations with Kamailio’s UAC module, I suggest you look into the Path extension and Kamailio’s PATH module as a means of relaying registrations inward to Asterisk. 

You can still benefit from security features of Kamailio in that case, while removing 90% of the complexity in your proposal. :-)
