[SR-Users] Topos_redis and loose_route

[Daniel-Constantin Mierla]

Hello,

topos is designed for sip traffic related to calls, it does not track
presence/subscribe dialogs, you have to skip them. Presence traffic is
usually terminated on a local server, no need to hide topololy, but if
anyone wants to add support for subscribe dialogs, he/she is more than
welcome to submit such enhancement.

For the non-call traffic, it does transaction level topology stripping,
ensuring that the reply is properly built for a request that was through
topos (this is aiming at MESSAGE requests, which can be routed via
interconnect trunks for SMS).

Cheers,
Daniel
