Hello.
Our branch office is moving to a new place where is no landlines, we'll have only internet connection available via WiMAX. We have one 2851 ISR with CME installed on it and fully configured to work with FXO to POTS. Now, we have 4 free POTS lines at our central office as well as 2811 ISR there. So plan is to configure 2811 ISR to work with FXO and trunk it via H.323 to 2851 ISR. Actually we don't need 2811 as PBX, it have to transfer calls from 2851 ISR to FXO and vice versa only.
Thus it should be like this:
OUTCALL (Cisco IP Phone) -> 2851 ISR (CME) -> Internet (VPN) -> 2811 ISR (FXO) -> POTS
INCALL (POTS) -> 2811 ISR (FXO) -> Internet (VPN) -> 2851 ISR (CME) -> Cisco IP Phone
Could you please advise a config of 2811 ISR to make it receive calls from 2851 ISR and then send to FXO and how should I reconfigure 2851 to send all calls to 2811 ISR?
Thanks.
