Hello Stephen, Thanks for reaching! For the Sandbox, you'll need 443, and the following ephemeral ports: 20100 - 20354. For the Ephemeral port range, you can just allow those for the following IPs from our two data centers: 173.38.221.89 and 128.107.93.228 Let me know if that works out! Jacob ... View more

Hi Stephen, In addition to jokearns's comment, we're also moving to a model where some ephemeral ports are required. The  range is is anywhere between 20100 and 20354. However, this number will likely grow in the future. Thanks! Jacob ... View more

Hello Jonathan, I checked the CUCM 12 link and it is working for me. You will have to log in/sign in to see the Sandbox. I am not sure about any plans to migrate/change APIs on CUCM in future releases. You may want to throw your question into our developer support spark room, where our evangelists should have a better idea about CUCM. You can join the room here: https://developer.cisco.com/site/spark-chat/ Please let me know if you've got any other questions. Thanks! Jacob ... View more

You would need to create the external database to use. If you installed the database locally and connected the VPN, you should be able to connect from the Sandbox Lab (where CUCM is) back through the VPN to your database instance. When connected on the VPN, you have to look at the IP settings, and grab the IP address that the AnyConnect interface has. That would be the IP address that CUCM should use to connect to your external database. Does that make sense? Could you give it a try and let me know if it works for you? If your database was running on a unix system, you could try use OpenConnect for VPN. Thanks! Jacob ... View more

Hello Peter, This is an always-on lab, so backend/administrative access is not provided. If you'd like to get this access, please make a reservation of the ACI Hardware Sandbox. The reservation-based ACI Simulator may work for you, and we have more open availability of this lab. Both of these labs offer full administrative access to APIs, SSH, backends, etc. Please give them a try and let me know if they work for you. More info on Reservation vs Always-On labs. Thanks!
