BT Falcon IP Phone on Cisco Soho 97 ADSL router (all traffic through VPN)

chris_lee100 — Tue, 25 Nov 2008 16:28:50 GMT

Hi,

I have today requested BT activate the voice feature on one of our many BT Business Total Broadband phone lines. We use cisco soho adsl routers on many of our lines. These are programmed with a script that ensures a permanent vpn link with our head office. All sub offices are on different sub nets etc. All internet traffic is routed in and out of our head office. My question is, will IP handsets such as the falcon work in a plug and play fashion (router DHCP etc) or will we need to re-write our scripts in our routers to accomodate this hardware and how they route to the outside world. Any help would be appreciated.

Thanks and regards,

Chris

Hi Chris,

I've spoken with the tech team and they've provided the following suggestions:

1) Is it possible to plug in a PC and immediate get internet access (without disabling DHCP)?

If so, the same is true of a Falcon phone.

2) The Quality of Service will be determined by your company's contention rules. So you need to make sure that sufficient bandwidth has been allowed.

3) You would be better rewriting the VLAN script to give voice priority over data. Or break out the of the VLAN locally.

Hope this helps.

Hi,

1) Machines plugged into the network cannot get instant internet access without their browser being configured with a proxy server address.

2) I understand you QoS answer, thank you.
