Remote Phones/Apps with SBC

[shermosillo]

I have an IPO Server Edition and an SBC for my SIP trunking. The protocol on the SIP trunk is port 5060 UDP. I am in the process of setting up remote phones/apps with the SBC. I thought i would be able to use the same WAN interface on the SBC for the phones/apps using TLS, but now looking at this, i am not sure that is going to work. Does anyone have any experience/knowledge with this. Would it be better to use a different WAN interface on the SBC for the remote phones/apps, or should i say is this the way i am going to have to go?

From what I recall (it's been a while since I've set up remote worker) you should be able to use the same physical interface on the IP Office and the SBC for trunking and remote workers. You will need to make sure that you have encryption configured since RW requires it, and you will need to make sure you have all the right flows for your RW configuration as well. The SBC will match the RW flows for stations and the SIP Trunk flows for calls. As long as all the flows are present everything will work.

I did a mixed SBC configuration once and had some problems that the wrong flows matched. To better handle that I used one physical SBC interface for both connections but gave those interfaces (A1/B1) additional IP addresses. That done it was almost like configuring one SBC for trunking and one for remote worker.

Need some help with IP Office?
