[SR-Users] UACREG to many Asterisk

Hi Javier,

Not knowing your config I could imagine that you can maybe use
ds_next_dst()
In a while loop to iterate over all setid members of dispatcher. That's not
tested and most people here would strongly suggest to use Kamailio as
Registrar.

Or you try some configuration that spreads the registration around to your
backends
Take a look at this thread

http://sip-router.1086192.n5.nabble.com/MID-Registrar-Example-td192277.html#a192339

Not sure if this works for you (due the path missing in asterisk 11 you
mentioned) but maybe gives some inspiration.


Kind regards
Karsten Horsmann
