From HacDC Wiki
HacDC is currently using three providers for the phone system. Google Voice - They provide the 202-556-HACK (4225) number. Twilio which allows dynamic scripting of your phone system through xml pages. voip.ms which is our SIP provider.
If you dial 202-556-HACK, you will be routed through Google Voice to Twilio and connected to our IVR (options below).
If you contact us via email@example.com or firstname.lastname@example.org, you will be routed through voip.ms which will connect you to our Twilio IVR.
We can also be reached via iNum +883-5100-09902515 or email@example.com SIP URI. iNum calls are routed through voip.ms and connected to Twilio. Due to most services not supporting iNum, iNum access is available through local access numbers in a number of countries. A list of access numbers is available at http://www.inum.net/what-is-inum-2/local-access-numbers/. An iNum number can be called from HacDC by dialing as a standard international number (instructions below in Phone System#Twilio IVR Menu:).
Calling from HacDC:
Dial as you normally would.
International numbers can be dialed using either US standard international access (011-country code-number) or European standard international access (00-country code-number) If you need access to an international number that the phone in HacDC isn't allowing access to, contact firstname.lastname@example.org for help.
voip.ms supports a service called SIP Broker for making connections between SIP providers. To find out if a provider can be contacted via SIP Broker, check out their Provider Whitepages. To call a SIP Broker number from HacDC, dial **275-Provider access code (including *)-phone number.
If a number will be called often or if people require access to a SIP URI, the Admin Team can create a speed dial which will be accessible by pressing #xx on the phone. voip.ms allows a total of 99 speed dials.
Current speed dials:
