Every time I reboot my Cisco IOS 800-series router, all the Windows 7 machines 'identify' the wireless network as being a 'new' network, forcing users to classify it as Home/Work/Public all over again (and more painfully, causing host firewalls to th...

My client would like callers who have dialled an extension and been put through to voice-mail to be able to return to the site's operator instead of leaving a message.I thought to callf-forward callers to an AA script instead of to the 'voicemail' ap...

I've frequently seen recommendations to have a separate "management VLAN". I guess the main ideas are:a) to keep managment-traffic and data-traffic out of the same Layer 2 broadcast domain? (So that rogue stations in the access-layer can't sniff ma...

Is minimising one's use of the private address space to avoid unnecesary potential overlap worth the hassle of having un-even VLSM lengths?I am designing my first non-trivial IPv4 addressing scheme in the 10.0.0.0/8 range. Just two small branch offi...

Thanks Karthik. Hi, yes all of the above are true, I believe. The telco is Telstra, and the product is their ISDN10, which I believe uses an NI-2 type switch. Their literature suggests that it is possible to subscribe to an ISDN-delivered transfer...

Hmm, won't the original caller hear the DTMF sounds on the line? Apart from that, I like this solution.Alternatively, I have located a whole bunch of information on doing redirects with TCBT (Two B-Channel Transfer) . In that scenario, you can appa...

Yes, that would do. The main point is not so much avoiding tying up the channels, but making sure that the eventual transferee has the original caller's number show up on caller-line-id. (Although avoiding call redirection charges and 2 channels is...

Hi Steffen,I was going to call it a bug on 9.2.1 and get on with my life. But if it's happening with later versions of everything for you, then I'll try to collect a few of my thoughts on it. Maybe you will be motivated enough to chase it up.First,...

Why does windows insist that the wireless network is 'new' after the router reboots?

Is there a better xfermailbox.aef?

If I want to summarise routes, I don't want the router I'm advertising to to be connected to the subnet, right?
