I've got a Freepbx 16 VM that is used purely in a lab, however it has a SIP client connection to SIPGate for inbound calls. Its also got some SIP IP phones registered and some trunks to other test devices. Its all working, however some of the admin web pages don't display and I get a PHP error...

I've had an issue for years with Mitel 5000 series IP phones and the passthrough LAN interface. It's a combined issue with Intel (and other) NICs. The switchport is configured with a Voice VLAN (single 802.1q tagged VLAN) and the untagged access VLAN. It's a Cisco switch so its a 'pseudo...

I still have a few Windows 7 workstations in an AD domain (2016 functional level). There are various GPOs that get applied and its a fairly robust setup. I have however a single Windows 7 Ultimate workstation that is having some GPO issues. It appears to be localised to this one PC. GPO...

I recently changed the default SMTP address for my small Exchange 2013 deployment. I noticed shortly after that when clicking the 'File' ribbon in Outlook 2016 to show the various options, the 'Account Settings' now shows the blank photo image with the 'Change' button below it. If you click...

I inherited a LaserJet 4250m with duplex unit recently. It has a non-HP toner installed so on power-up after the POST the display says 10.00.00 SUPPLY MEMORY ERROR and the attention LED flashes. If I press the green 'tick' button it then briefly displays [code]NON HP SUPPLY INSTALLED. Economode...

I am trying to understand if I have a problem or not - everything seems to be working OK but I have noticed some odd DNS queries from Windows 7 clients for my 2008R2 Domain. All the DCs are 2008R2 and the domain functional level is 2008R2, all the DCs are also DNS servers and all my zones are...

I want to prevent all routes except the default from being advertised down an interface. I have RIPv2 running between a core and an access switch. The access switch doesn't need anything but a default so I want to prevent the core from advertising anything but the default. At the moment all...

I am currently running two Dell XPS i7 Desktops with 24GB RAM as Windows Hyper-V servers at Home. I have various guests that I use for testing, plus my home AD domain across about six guests (some Windows 2003 & some 2008R2). I am hitting some limitations with some guests that I want to...

In a typical WiFi hotspot a wireless client is assigned a private RFC 1918 IPv4 address. When accessing the Internet this address needs translating to a public IPv4 address, this will happen on a gateway/router (you can verify what you appear on the Internet as with sites such as...

I have an unlicensed Exchange 2010 server. According to the GUI There are 11 days remaining and I was hoping not to rebuild this when it expires. I have read that it will continue to work but will prompt for a license key. Has anyone let their trial run beyond the 120 days? Is this what...

With IPv4 I have always created reverse lookup zones that reflect the actual subnets in use - i.e. separate zones for each subnet 10.1.1.0/24, 10.1.2.0/24, 192.168.1.0/24 etc. If you have a site that has its address space nicely carved out and can be summarised would it be valid to use a...

If you only have IP Phones and SIP trunks are gateway resources required? If there is CODEC translation required then obviously this must be the case but if every endpoint is doing G.711a (or G.711u) then there should be no need for a call to go through a gateway? I have a test MX-One under...

I have Outlook 2007 on a Windows 7 x64 PC. It is configured with three accounts - an Exchange 2007 mailbox, a POP3/SMTP account with an ISP and Hotmail. For the past few weeks I have noticed that the 'Empty the Deleted Items folder upon exiting' setting is not working. When you exit Outlook...

I am attempting to use Asterisk (FreePBX) as a 'transit' trunk between a service provider and an internal Cisco Call Manager. The reason for this is Call Manager cannot be a SIP endpoint - i.e. it won't register and the SP accounts are just simple SIP accounts. I have everything working and...

I have a 'virgin' install of FreePBX and I am using it purely as a SIP-to-SIP gateway sat between a Cisco CUCM 7.1 server and the Internet where my SIP provider is. Asterisk is being used as CUCM doesn't perform SIP registration. This is all for testing. In my NetFlow logs from my Internet...

I upgraded a CUCM 7.1 server (7.1.5.2000.6) to the latest version of 7.1 (7.1.5.33900.10) and as far as I can tell the upgrade was sucessful. I switched versions and it booted OK. Now however the ccmdmin page will not display - I get a 404 saying /ccmadmin/showHome.do as unavailable. I can...

I need to configure some source & destination based policy-routing to redirect some traffic to a new firewall. The policy decision will be specific source hosts to some destination networks. Traffic for internal networks from these hosts should continue to route normally but to these specific...

I posted this ages ago - Edit the IPSec (offline request) Certificate Template for MSCEP? http://www.tek-tips.com/viewthread.cfm?qid=1275487 The thread has been closed but I managed to get this working and have replaced the IPSECIntermediateOffline Version 1 certificate template with a Version...

I have some older Extreme switches (ExtremeWare OS) that support LLDP but not enough to get the Mitel IP Phones to discover the Voice VLAN. No problem - I have routing between the Data (access) & Voice VLAN so I'll configure Option 125 on both the Data & Voice VLAN DHCP Scopes. Since LLDP is...

Since someone has raised a question on IPv6 and Cisco IP Phones I assume people are now actually looking at this? I know IANA handed over the last /8 block a few weeks ago so its probably got to happen at some point. Anyway according to this document on CCO...
