Help with VOIP on Cisco 831


I am trying to get some configuration examples for Cisco 831 VOIP.

I have 3 office with 768mbps SDSL going into each and a Cisco 831 and I wish to configure them for VOIP.

I've looked on the Cisco site but cannot seem to find 831 specific examples.

I am not sure what you are trying to do ,I am assuming you have connected three 831 cisco routers to the internet ,now you wish to do voip between these three sites .831 does not support Voice , check the following Links for routers which support voice,

formatting link
anthor option which you could try is Install an asterisk server at one of the locations behind one of these routers on public ip and register sip phones on the internet from the other sites .This would not involve buying more hardware if u use sipsoftphones.Also you could use ATA boxes behind these routers and configure them for differrent Voip providers like Vonage or FWD.

Thanks Aman
