Many enterprises are considering migrating to VoIP. Network administrators have many considerations. The SearchVoIP.com website interviewed Doug Hyde, product line manager of the stack switch of 3Com, about some tips on mitigating this transition and ensuring that the network is ready for VoIP. Q: How can enterprises ensure the service quality of existing networks? Doug Hyde: an important aspect of ensuring

Overview explanation VoIP is the abbreviation for voice over Internet protocol, meaning to transmit voice over the Internet (Internet). VoIP technology is also often referred to as network telephony, IP telephony, or Internet telephony technology. VoIP's most basic function is to provide internet-based, low-cost voice and fax services. It can also extend further to ip-based voice services.

on mobile voice services, however, the performance evaluation results of traditional MANET for VOIP services are always unsatisfactory. Here, people are very concerned about whether the wireless mesh network can meet the quality requirements of users for real-time voice services. Iometrix, a professional testing company, conducted the first performance evaluation and testing of Wireless Mesh Networks Based on the draft study by the IEEE 802.11 Workin

With the improvement of the Wi-Fi standard, the size of 802.11 chips is decreasing, and the functions are expanding, the feasibility of the VoWLAN telephone system is also gradually improved. Dual-band mobile phones can use WLAN connections to provide reliable in-house voice services, while broadband telephone services connect notebooks through WLAN. On the other hand, the network phone number based on WLAN can easily support multiple mobile phones with only one WLAN base station, which is no in

With the development of China's routing industry, we have also promoted the update and upgrade of the VoIP router technology. Here we mainly introduce how to do a good job in the security vulnerabilities of the VoIP router technology. As the bandwidth of the Data Network continues to expand, it is possible to reach the desktop by Mbit/s or even Gbit/s. The increase in bandwidth also provides powerful precon

VOIP, also known as IP phone or IP phone, is the abbreviation of Voice Over IP. This technology is used to encode, digitize, compress, and compress Voice signals into Compressed Frames, then, the IP packet is converted to the IP packet for transmission over the IP network, thus achieving the purpose of voice communication over the IP network. The IP Phone greatly improves the utilization of network bandwidth and reduces the communication cost. its wid

VoIP has become a major topic in the era of integration. How to better utilize the functions of VoIP in the aspect of open-source and throttling, and reduce the communication costs of enterprises and individuals has also become a common concern in the industry. At the beginning, as a technology used in Internet applications, VoIP was widely loved by Internet user

We now have a lot of knowledge about VoIP technology, and we are almost at risk to talk about other applications and usage knowledge. In the use of VoIP technology, we will transmit voice signals in the IP network. However, there are also many technical needs to achieve long-distance IP network spanning. ◆ Session edge controller SBC) Technology Session edge controller SBC, or session Controller) is a

Implementation principles and key technologies of VOIP: basic principles and implementation forms IP telephone systems convert analog signals of common telephones into IP data packets sent by computers over the Internet, at the same time, it also converts the received IP packet into a sound analog electrical signal. After the conversion and compression of the IP Phone System, the transmission rate of each common phone is approximately 8-11 kbit/s band

As the bandwidth of the Data Network continues to expand, it is possible to reach the desktop by Mbit/s or even Gbit/s. The increase in bandwidth also provides powerful preconditions for voice transmission over the data network. At the same time, the VoIP technology is becoming increasingly mature. topics such as voice compression and Qos quality assurance have been widely discussed and reached consensus. It can be said that the

As long as your network architecture management and preparation are in place, VoIP will be excellent on the wide area network. Enterprises should know that the performance of the VoIP system is no different from that of the traditional TDMPBX. According to MarkArman, vice president of the ShoreTel marketing department, using VoIP on the wide area network requires

With the development and application of VoIP, VoIP has attracted more attention from hackers, network scammers, and spam email makers. As a result, the security of VoIP has become increasingly prominent. Typical VoIP Security problems include: · Anti-virus and attack prevention: the security of

usable. that's why the concept of SIP proxy exists: the proxy is responsible for routing cballs whatever the IP address of end-users is. voIP OperatorsCompany are deploying sip proxies on the Internet to get sip callrouted for their subscribers. Direct Dialing is not always available on the internet due to changes in IP addresses, firewalls, and other factors. this is why there is a sip Proxy: The SIP proxy can implement the routing function without

VoIP decisions should not be based on technology, but on how it affects your business.

I. NAT/ALG Mode Normal Nat implements address translation by modifying the UDP or TCP packet header address information. However, for VoIP applications, address information must also be included in the TCP/UDP net load, ALG Mode means that the VoIP Terminal in the private network fills in the private network address in the Net Load. The address information is changed to the external address on the NAT when
