I'm using a SRP521W-U. I've set up a SIP account on Line 1.
I would like to be able to answer incoming calls on both FXS1 and FXS2.
How do I achieve that both ports will ring?
This is a good question "cisco business router" .
With the same sip account I need to answer and make call on both FXS1 and FXS2 too.
If there is not the possibility to do that I am asking to the cisco guys if there is a way to implement a more dynamic call routing on the device in the next firmware release.
If your provider supports multiple registrations, you can configure the same credentials on both lines, FXS1 and FXS2.
By default, FXS1 uses 5060 port and FXS2 5061 ports.
In this way an incoming call will be forked to both FXS interfaces that will ring simultaneously.
The negative aspect regards the busy message. You will get the busy only when both line will be busy.
