2What is SIP and SIP Trunking?
SIP stands for Session Initiation Protocol. It is a standard for signalling and controlling multimedia connection sessions. On the other hand, SIP trunking is a way to deliver voice and video communications over the internet.
3Can you provide test results for both copper and fibre cabling?
Yes, we have testers in-house that allow us to record all test results, which can be emailed as a PDF for your future reference.
4Bandwidth requirements?
To access SIP calls, you'll need to ensure you have the proper bandwidth. As an industry best practice, you should therefore reserve at least 64 kbps (kilobytes per second) for each SIP call. We can even do this for you in a network.
5Is SIP the same as VOIP?
SIP calls are not the same as VOIP (voice over IP) calls. VOIP is any type of voice call made over the internet, whilst SIP is one protocol used to achieve VOIP.
6Why do businesses use SIP trunking?
Most businesses opt for SIP trunking because of its cost-effectiveness and many disasters recovery options. When using SIP trunking, you pay a lower monthly fee for a far superior solution.
7Is the sound quality for SIP calls good? 
One of the fears you might have when switching from ISDN to SIP calls is that the audio quality might be poor. Thankfully, you don't have to worry about audio quality because SIP providers leverage a tier-1 network with high powered routers. That's why SIP calls sound quality is up to par with calls made over a traditional phone line.
8How many SIP trunks will a small business need?
Once you know how many calls your business makes daily, it'll be easy to determine how many SIP channels your small business will need. Talk to us, and we’ll quickly be able to give you a good idea, and better still, we can monitor this in future and advise if you need more or even less SIP trunks.
9Network requirements
Your network needs to be adjusted to allow SIP traffic. In addition, it needs to be configured to the optimum setting so that SIP can perform at the best level. Red Rock are specialists in a wide range of routers and firewalls and will be happy to assist in setting this up. In addition: The latency for your network should be 150ms at the very least. Your internal network jitter should be less than 100ms. If your network is not ready for SIP, the call quality won't be good. Are you worried about your internet quality for SIP calls? There is always a thread of other applications sharing your Internet, which reduces your Internet quality. If you need to make a SIP call and this keeps happening, you can dedicate a private internet connection that's reserved just for SIP calls.
