SIP Trunking FAQ’s
- What is a SIP Trunk and what does SIP stand for?
- Session Initiation Protocol (SIP) trunkingis a service offered by a communications service provider that uses the protocol to provision voice over IP (VoIP) connectivity between an on-premises phone system and the public switched telephone network (PSTN).
- Who makes the SBC (Session Border Controller)?
- There are a number of manufacturers that we use. We’ll help find the one that works best with your system. For Mitel (ShoreTel), we recommend the Ingate SIParator line of products.
- I have one site that is out of contract on their PRI, but the rest of my sites are in contract for another year. Can I move that site now, or do I have to move everything at once?
- We can move a single site onto SIP now, and leave your other sites as they are until your contracts are at term or you are ready to move them.
- Where can I get phone numbers? Do they have to be local to my site?
- We can provide phone numbers almost anywhere in the United States, and they do not have to be local to your physical location.
- Can I bring my current phone numbers with me?
- Yes. You can “port” your current phone numbers over to our SIP trunks.
- Are there charges involved with reserving blocks of numbers in the SIP world?
- Yes, you will be charged for any phone number on your trunks, whether it’s in use or not.
- If my internet goes down, do I lose my ability to make phone calls?
- If you have a single internet connection, yes. We offer a robust set of failover and backup options to help prevent these outages.
- Are there options for private connections, if we don’t want our traffic going over the open internet?
- Yes, we have private line, MPLS and SD-WAN options available.
- Do SIP connections honor any QOS on the open internet?
- Once a call is on the open internet, we cannot guarantee QOS. With a private line or MPLS option added on, you’ll have QOS across that circuit.
