For a remote site, my customer wants a group of 2*E1, each being connected to one ISR gateway with SRST.
In cas one WAN problem, what happens ? How should I configure SRST to be sure that all the phones will be connected ? Do I need to buy SRST licenses for all my phones on both routers ? Half on each routeur ?
What about incoming calls : how will the be routed to the phone. Example. My Phone is connected in SRST on router 1 and a call arrives on E1 of router 2 ?
Thank you for your help !
