[asterisk-users] Max number of Registrations with and without Realtime

[Grey Man]

Sounds more like a database problem than an Asterisk problem. Asterisk
shouldn't care if you have 50 million accounts in your realtime db
provided it gets timely responses to its queries and updates. I use a
Postgres database  with Asterisk and realtime and have over 5000
registered SIP accounts in the one db.

Asterisk is very snesitive to unresponsive realtime db's (and
unresponsive DNS while you're at it). If your db starts to struggle
you can expect console freezes and other oddities on your Asterisk
servers.
