[Serusers] SRV failover question

[Paul Antinori (pantinor)]

Hi,

Regarding the SRV query addition in (ser-0.9.7-pre7), when the call
fails on the first priority destination, it never seems to attempt to
send the INVITE to the second priority destination in the SRV response
list.  Is there anything else to script in the ser.cfg file to get this
to work?

Thanks for help,

Paul
