SIP Trunking Options for Mixed Networks

jim blog 061917.pngBack in June, I wrote a blog about using Gateways for SIP trunking if there are PSTN lines inside the enterprise.  And this makes sense for sure given 40% of enterprises are still PSTN on their internal networks.

But there are other options for interfacing your enterprise with a SIP trunk. Certainly, an SBC is a great choice if you have SIP throughout your network.  You would need to enforce SIP security at the network ingress point of any SIP trunk.  There may be SIP to SIP interworking to do as well.  SBCs can do all of that.

So, what should you do if you have a mixed network? 

1. You can deploy a gateway and an SBC.

2. You may already have a gateway and then wish to add onto that with an SBC.

3. Or you may deploy an integrated gateway/SBC box, allowing you to have a SIP trunk coming into the enterprise, and allowing you to migrate from PSTN to SIP at your own pace.

Dialogic has all the options listed above.   If you are interested in utilizing a SIP trunk and starting to standardize your communications on SIP, please contact us. We’d love to help you.
