So I decided that it would be fun to play around with Call Manager Express in my home lab and get some experience with SIP and Cisco voice technologies. Initially, I held back from playing around with it since I didn’t want to pay for DIDs and SIP trunks (despite them being very reasonable) just for a lab environment. After some googling, I came up with this…
Free SIP trunks for lab testing! What a steal! I’ve had some brief communications with the guys over at SIP-UA and they are very helpful. It works like this…
-All lab users share a single DID. When you call the DID, it asks you for your lab extension (you get assigned one when you sign up) and then forwards the call to you.
-Outbound calling is allowed in the US but limited to 2 minutes
-No monthly fees, no commitments, and no contracts
Pretty cool huh? I’m a big fan and I think it’s really nice of the guys over there to offer this service to people who are trying to learn the technology.
In the next post, I’m going to a single phone base CME setup using a SIP-UA SIP trunk.
