Deploy Cloud Connector Edition with Internet SIP Trunk. Now Skype for Business Online – Cloud PBX is accessible, we’re already deploying several cases of this new exiting version. Where customers are happy to leverage Cloud PBX, but couldn’t or wouldn’t get numbers from Office 365 directly, Cloud Connector kicks in. Where Cloud Connector – and therefore Microsoft – assumes you’re using a dedicated SIP Trunk or Gateway, having a leg inside your local LAN, there’s still the likelihood to make use of an internet-terminated SIP Trunk.

WARNING: this might be technically possible, but probably isn’t backed up by Microsoft, or by a SIP Trunk provider. Use this for your own personnel reference and testing purposes. This blog describes the steps to become taken to implement and connect a (Pilot/test) SIP Trunk, terminated/connected on the internet directly instead of VPN or dedicated line. Topology Microsoft did a great job describing the Cloud Connector that exist here <https://technet.microsoft.com/EN-US/library/mt605227.aspx>.

Additionally to this, keep in mind the subsequent: In our situation we’re connecting a SIP trunk from an ITSP that will be Lync/Skype certified. To get a SIP trunk, we two endpoints:

  • IP B, Port 5068: Cloud Connector ended public IP Address and default TCP Port IP and Port A are in the Cloud Connector.

IP and Port B are non-existent throughout the initial deployment. The cloud connector can be situated anywhere, but there’s one additional prerequisite: we should instead add another, physical network connection which we hook up to “the internet” directly.

Deployment

To deploy a Cloud Connector having an Internet SIP Trunk, focus on deploying as usual, and mentioned/described:

  • Prepare host server
  • Install Sfb Online, cloud connector software
  • Configure deployment and prepare cloud connector.
  • Prepare BaseVM
  • Prepare office 365
  • Deploy cloud connector

When all VM’s are executed creating as well as the script reports ALL OK, the fun begins! Configure SIP Trunk network. To get this done, we must create another virtual network in Hyper-V. This network bind the “SIP Trunk” physical network connection, as described earlier: We call it “SfB CCE SIP Switch”, even as used the defaults in Cloud Connector to the other networks and this way, it keeps the identical format.

However, it’s just a name…Now; we give a new Virtual Network Adapter to Mediation Server VM: In our topology, we need to set a LAN ID but this, of course, depends on your network build. Again: as long even as can configure the genuine IP inside VM, we’re all OK.

Configure VM

Next step is always to visit the Cloud Connector. This needs to become carried out in a console session. We know the password to the VM, even as have given this in during initial deployment. Once signed in, we configure the network topology once we used to in different on-prem situation:

  1. Locate and Configure Network Adapter with Internet IP:
  2. Configure static route:

Of course, again this depends upon your SIP Trunk provider’s requirements and your network topology. Either configure default gateway on public IP and define option to internal network, or the other way around – we did the latter to make a little more “security”, in addition to the firewall configuration where we only allow traffic between ITSP and our IP. Now reboot or restart services on the mediation server, and when all correct – job should be done!

Again, this is actually the least secure and qualitative connection we can think of – however it is cheap and fast to create, acceptable for initial test set-ups. Also bear in mind, our next blog will take care of a fundamental troubleshooting method if this isn’t working.

Defending

The Enterprise Edge: SIP Trunk Edition Industry Trend: Moving to Cloud In case you have been offline for your past few years, things are moving on the cloud. Virtually everything. Moving applications towards the cloud promises increased flexibility, scalability, reliability and accessibility with decreased management costs.

Many enterprises want to achieve exponential benefits by moving their UC platforms towards the cloud. Microsoft’s Entry: Cloud PBX Cloud-based UC solutions, like Microsoft’s Office 365 Cloud PBX, combine UC’s promise of increased efficiency, productivity and business agility with all the inherent benefits of a cloud deployment. Microsoft’s offer is unique because it integrates collaboration and communications in the Office experience that users leverage every single day. The familiarity of Office and Skype for Business help drive adoption throughout an organization.

The 3 Domains of a Cloud Deployment

Although moving your UC deployment on the cloud does remove most of the administrative burden, it adds some complexity when it comes to traversing multiple domains. The servers and licenses reside in the hosting domain (Microsoft for O365), but the users in addition to their devices reside inside the customer domain. To add further excitement, connectivity between the client and Microsoft domains go through the transport domain, which may be a variety of carriers that connect the buyer domain to Microsoft.

Each domain has a different responsible party that is accountable: Although enterprises can enjoy the advantages of shifting a lot of responsibility to Microsoft, this topology doesn’t remove the client from responsibility for own domain. Further, three different domains, each with its own accountability, will add to finger pointing making diagnostics/troubleshooting more complicated. A Hybrid Option: Cloud PBX with On-premises PSTN
