[cisco-voip] Deploying 7961 Phones Remotely with ASA5500?

Thu May 7 10:53:14 EDT 2009

Steve,

If you set it up as Ryan suggests, are you planning to power the phone
with a brick? Be ready for some serious troubleshooting since most of
your remote users will not be extremely helpful. I've gone down this
road for the last 6 months using the ASA setup and we are still
streamlining the process. 

How do you plan to create the tunnel to HQ?

Carlos

Your Linksys router is going to be doing NAT/PAT and I'm pretty  
confident they don't support SCCP fixup.  You will need the phone to  
either be in the DMZ or have a vpn tunnel behind the Linksys.

Yes. I am just trying to make sure that there is nothing other than  
generic router (Linksys or whatever someone would normally have in  
their home) and the phone which are necessary to work with the the  
ASA55XX back at the network site.  We have been using VPN3002 boxes  
which are expensive and sometimes problematic to set up/program.  
Thank you for your feedback!

What do you mean by necessary? If you can get your Linksys to setup a  
vpn tunnel then yes

Thanks. Only the phone is necessary, correct?

Only the hardware needed to establish connectivity back to the  
cluster (VPN or direct via a t-1 or other circuit), and provide power  
for the phone.

You could use an ASA5505 and that does poe and the vpn tunnel all in one

Simple question:

What hardware is required (if any) at the remote location to allow a  
Cisco phone to work?  My understanding was that hardware was  
unnecessary....that the phone could just hang off a regular Linksys  
router at a person's home. Please advise.  Thank you!
