This is a short list of recommendation to keep your business secure:
- We recommend to change you Administrator password
- Change Default Voice Mail password
- Delete any email containing SIP account credentials
- Do not share SIP account credentials
- SIP TRUNK Admin, change SIP password and Set Balance Warning Thresholds
- Removed any router port forwarding. Your SIP service only need SIP ALG disable
- Block any router port 22 access
- Maintain current Firewall and Router firmware
Ports used by UsVox Hosted PBX user devices
Our advice is to always disable Router or Firewall ‘SIP ALG’ before you begin to open ports on your network security settings, if your Router or Firewall don’t have any disabling for SIP ALG choices we strongly advise you to contact your Router or Firewall technical support and let them do the work they are expert on this matter.
The following are the ports and protocols that Hosted PBX user devices use.
Port numbers and Protocol
UDP 5060; TCP 5060, 5061 SIP, SIP TLS
UDP 35000-65000(assigned dynamically) RTP, SRTP
Allow everything from/to the VoIP device from/to the networks 208.89.104.0/22 and 199.180.220.0/22.
Allow UDP traffic sent to the device to all ports higher than 1024. It is for media.

Audio quality problems
You can experience voice quality issues, like on a tunnel, jitter, scrambling, etc.
These are related to bandwidth and latency of local ISP (Internet Service Provider) and on site network infrastructure, Here are some suggestions to resolve audio quality issue:
1) Internet traffic
Internet traffic by users on a system with improper Network services setting, uploading or downloading files, streaming video or music can cause issues in your network performance and quality of your voice services by internet.
A free internet tool to see problem live on the net is “Internet Health Report”

2) Delay or issues with the transmission of packages between you provider and you phone device (Latency), issues with package loss, or any problem with the ISP can cause issues in your network performance and quality of your voice services by internet. you can always Traceroute our services

3) Network cabling installation:
Is your wiring correctly installed? Quality on the data wiring installation can cause issues in your network performance and quality of your voice services by internet

4) Network equipment:
The setting of QoS will prioritize the SIP devices to have higher priority over the rest of the network devices without compromising the bandwidth used to stream video, audio or up and downloading files. If your equipment is outdated, or not connected properly can cause issues in your network performance and quality of your voice services by internet.

- If you are using multiple switches connected in different locations (typical scenario a small Data switch under your desk)
- Using damage cables to connect them (Cables that users walk on them or are pinched by door or furniture)
- Power not protected, used UPS or search protected strips.
- Old equipment or using old firmware.
Can I bring my old number?
Yes you can port most DIDs/numbers. Depending on the carrier who currently has your DID/number you may or may not be able to port you DID/number. This process can take up to 6 weeks depending on your current carrier. An LOA (Letter of Agency) is needed to initiate an LNP (local number port). See the LOA FAQ for more details.
LOA for Porting and porting procedures:
1. The Letter of Authorization (LOA) need to be sing by the business owner or the person in charge for the account of the loosing carrier.
2. Fax or email with a the sing LOA and copy of the Phone Bill for the porting to be submitted to [email protected] or Fax to 17862755889

Can I make calls to 911 Service?
Can I make calls to 911 Service? Yes, but to enable the E911 Service, you must register the phone number(s) you use for caller identification (CID).
Calling 911 using VoIP services differs from calling 911 using traditional landline service, and certain situations may affect the E911 Service response.
When you call 911 from a registered phone number with the E911 Service, the call will be associated with the physical address linked to that phone number.
If you call the E911 Service from an unregistered phone number or device, you must provide the address where the emergency is occurring. In this case, a fee of $350.00 will be charged for each call made.
E911 Registration Terms and Conditions

How it works?
Just like a desktop PC is connected to the internet by a network cable a Hosted Internet PBX similarly works in the same manner. Because your PC is connected to a router all you have to do is simply press a button and your accessibility to the internet is granted. So long as your service is up and running you will be able to surf, send email, conduct online video conferences, and just about anything else you might need or want to do on the internet.
So in concept your IP phone is designed like a mini-computer to act as a fully functional business telephone. The IP phone plugs into your internet router using a regular network cable and once turned on can make calls, forward calls, hold calls, transfer calls, check voice mail, and perform all the functional tasks you expect out of a business phone. As long as the IP phone has internet connection it will be fully functioning.
This allows an IP phone to work without geographical boundaries, enabling it to be taken anywhere in the world that has an internet connection.
Hosted Internet PBX service does not consume any notable bandwidth until you make an external phone call. Usage includes checking voice mail and dialing internal extensions within different networks. At the time you receive or make an external phone call the bandwidth usage will be approximately 90kbps (kilobits per second).
If you have 2 external calls running at the same time the bandwidth consumed will be 180kbps until either one of the calls hangs up, at which point the consumption of bandwidth drops down. This means you will take the maximum amount of external calls that your company receives at the same time, and multiply by 90kbps.
Other network setting must be taken consideration, like disabling SIP-ALG on the Firewall, setting routing tables (QoS) to improves quality, etc.
