Stupid CsAnalogDevice Tricks

No need to throw away all the old phones - you've got CsAnalogDevice!

Can be integrated into Skype for Business with CsAnalogDevice

Anthony Caragol recently set the Skype for Business community a little challenge:

Never dare a Texas girl.

Previously, a local admin at one of the sites we recently rolled out Skype for Business telephony at needed some mobile phones to be directly callable from the client AND to be identified by the same name when calling Skype for Business users. I vaguely recalled there being some way to integrate older phones and faxes and hit upon CsAnalogDevice.

Like CsCommonAreaPhone, a CsAnalogDevice is an Active Directory Contact object and is completely inaccessible from the web admin interface, but unlike CsCommonAreaPhone, is just a pointer to a phone number.

Here’s how you make one for a German mobile with 0151/12345678 – +49 (151) 1234678:


New-CsAnalogDevice -LineURI 'tel:+4915112345678' -DisplayName 'Maintenance Crew' `
-OU 'mandie.net/Contacts/Phones' -Gateway 'nue-sbc01.mandie.net' -SipAddress `
'sip:maintenancecrew@mandie.net' -RegistrarPool 'nue-FE01.mandie.net' `
-AnalogFax:$false -DomainController nue-dc01

Wait a bit for address book propagation, and you can then click to make Skype calls like any other Skype for Business endpoint.

Back to Anthony’s question – you can only forward to a single number in the client and in SEFAUtil, and delegates and team members must be proper SIP addresses (will need to see if an external SIP address can be shoe-horned in those lists…)

I made CsAnalogDevices for my mobile and home phones, waited awhile, then used SEFAUtil to add their SIP addresses as my “delegates” and set immediate forwarding to delegates. Result! Both rang when I called my main number, and I was able to answer on either.

In the desktop client, I could see both display names as my delegates.

To test:

  1. Can Analog Devices be added as delegates and team members from the desktop client instead of SEFAUtil?
  2. Does this still work when the Analog Devices are on different PSTN gateways?
  3. Is this available in Skype for Business Online?

CsAnalogDevices can make any phone number, internal or external, a more integrated part of your Skype for Business environment.

What weird and/or wonderful use have you found for CsAnalogDevice? Any other obscure endpoint types?
