SIP trunks are a fairly new way to provide voice website traffic in your firm. These are generally trunks which can be delivered through the internet as well as other method of IP website traffic. This actually is a move from traditional T1 that had been the conventional to create several facial lines of visitors in to a place. So, why the change? IP is already at the center of telecommunications. Be careful when evaluating these trunks as replacements for your T1 and make sure you have the right reasons to make the switch, even though SIP trunks do offer some nice features. Listed below are some pros and cons of SIP Trunking:

Pros:

The most significant factors we experienced in transferring to SIP trunks were convenience problems. Say you have workplace in Florida with a cell phone system and one or many T1 terminating there with 100s of neighborhood phone numbers. What follows is a difficulty until you have yet another Florida workplace using a telephone capacity and system to handle the more circuits. The main trouble with traditional T1 support and local suppliers is these phone numbers are locked into Florida and should possibly terminate to products in Florida or even be phone forwarded which could run more than $.08/moment. If you running call center with lots of calls, this can add up quickly to thousands of dollars rather quickly. SIP allows you to terminate these phone numbers to a provider who is able to then provide them around the globe around an IP group for the similar costs you were used to or much less.

SIP trunks may also be easily scale-equipped. In past times with T1, you had 23 trunks for each line, or 23 phone paths for every T1. If you required more, you requested yet another T1. Additionally you were required to have one more user interface and also place in your PBX to handle the cards to user interface the T1. SIP trunks range less difficult with simply including sessions and bandwidth, the online similar to trunks within a T1. The program stays the same, an internet connection, and this usually can be completed around the fly or with small downtime which can be fantastic.

Cons:

Upfront expenditure is there. We need a border control which happens to be in which the additional IP that talked to the SIP company resided. We ran this option more than our current MPLS network to permit for QOS along with other prioritizing functions, therefore the bandwidth to assist voice would have to be improved and this is an added cost. This all needs to be taken into account, even though we were looking to offset the previously mentioned call forwarding charges, so there was quite a bit of costs that we were offsetting which still made it viable for us.

Another large con is the issue of any SIP trunk area failure. We found out the tough way, that the phone numbers directed on the SIP trunk area had been fundamentally trapped there when it comes to an outage. If there was a problem at the primary site, we only had one location with SIP service and we later found out that the numbers on SIP can only be routed to other SIP trunks. This used on all community amounts which were being shipped to the SIP trunks. So even though we had other T1 service in our account, our numbers were stuck until the issue was resolved. The solution? Increase every little thing stated earlier and replicate the service at one more site. This is the only way to obtain it if DR is a priority for you.

SIP Trunking is a bit of a complex solution and it has little quirks, but in the right situation, it can be a huge cost saver in the long run.
