SIP Trunking is the most popular way to add PSTN connectivity to a modern UC solution.
A few words of advice:
- Fax support: if the UC solution will need to transfer faxes, you need to make sure the operator has official T.38 capability.
- Routes quality: these should be extensively tested over national, mobile, and international destinations for the following:
- Audio quality
- Connection speed
- CID shown on the remote side
- Set custom outgoing CID: a great feature for mobility and call forwarding
Over the last few years, there have been many rumours about an increased risk of the “direct sales model” with launch and domination among the companies that form the UC&C backbone worldwide.
Headlines from the most respected publications in the industry feed the readers with such things as:
“The … Cloud business will be driven by a new end-user-focused engagement model”
“Resellers Beware: More Companies Now Selling Direct”
“Are Cloud Vendors cutting out the Channel”…etc
However, as this is still a new model for many Vendors, many Channel Partners are living a calm life in their “Bubble” feeling the relationship that they have with their customer was safe. Continue reading
The biggest factors to consider when choosing devices that will connect to your UC solution are: determining the required installation time and avoiding installation-related issues (lengthy installations, device-related errors, etc.).
FXS / ATAs
Ideally, all devices connected to a modern UC server should be IP endpoints (PCs or SIP Phones).
In practice, there are many reasons to stick to analog FXS ports to connect analog devices:
- Users do not need advanced features on their endpoints
- Most fax machines have no built-in VoIP capabilities and require an ATA
- Analog modems connections
- Substituting many twisted pair cables with CAT-5 or CAT-7 cables might be:
- Too expensive
- Not possible because the resulting Ethernet cable would be longer than the maximum allowed Ethernet length (100 meters)
In such cases, the easiest way is to connect an ATA, which is a converter between SIP VoIP and analog interfaces.
In the previous blog article (Insight into the user endpoint) I listed user endpoints. This time I am going to characterize what advanced services can be implemented via SIP phones.
On legacy systems and modern VoIP systems, feature keys can implement a large set of services:
- BLF (Busy Lamp Field), which displays the status of colleagues
- Parking slots
- Speed dial
- Send DTMF
- Trunk / line monitoring and use
Verify how many of these keys your users will need. Also, consider the possibility of providing such advanced services via the UC Client. For example, the user can own a basic VoIP phone for calls but manage all other operations (presence, monitoring, etc.) via the UC client on the PC.
Are you considering investing in UC&C to improve your company’s productivity?
Telephone calls bounce between internal employees, they have to handle millions of emails and exorbitant travel costs: at the dawn of 2018, it is clear that UC&C is the definitive remedy to inefficiencies in internal communication that cause loss of productivity. However, there is one aspect that you must carefully evaluate before moving toward UC&C – a fundamental factor on which the success of the company’s entire investment depends. Because even if you implement the most advanced technology available on the market, the risk of seeing all your efforts nullified is around the corner. And, as you could read from the title of this article, the attack you may come across is a real stab in the back… Continue reading
