In the system we use here, all clients register with SER and the invites are forwarded to Asterisk
only when we need any PBX feature. Normal calls are forwarded by SER alone, which we found
scalable, as it doesn't handle RTP streams. When the clients register with Asterisk, all invites
go through Asterisk, which handles media. Of course, we can have Dial statements which dont
request for pbx features, but designing such a complex dialplan was difficult. Also, we wanted to
avoid frequent reloads of Asterisk due to the change of dial preferences by users.

AFAIK, there is no such built-in mechanisms to acheive scheduling in a random manner. The failure
routes follow a sequential order. However, you can implement this feature by adding a custom-built
module to SER.
