Use an SIP provider to setting up a VoIP service might cause several problems, include the lack of standardization. Different parameters are required to use the same SIP client with various SIP providers. If different clients want to connect to the same SIP provider, they will need new pieces of information. Sometimes, many of new users who are getting into the field of SIP VoIP for the first time are being confuse of this problem. They need to set a few parameters which are confusing, such as authentication username, outbound proxy servers, STUN servers, codec, etc. Users like us might be able to set those parameters in proper way, if we can figure out for ourselves or wait for connection to an SIP server has standardized interface. It’s easy to figure out how to automatically provision the SIP client. Simply contact the ITSP, if you have obtained a plan of hosted PBX.

The network administrator and the ISPs may be imposing settings for the local security and firewalls. But, you can bypass it by using the outbound proxy server. This is because an ISP will block the most commonly used port to restrict VoIP call on its network. The SIP client cannot use regular means to initiate VoIP calls to a server of SIP, without this being accessible. In order to do it, workaround is required. STUN server is a one well known way to achieve it. Make sure that your outbound proxy has configured is the other way to the SIP server

The SIP client will send a request to the outbound proxy and it doesn’t have a VoIP call appearance. It is merely the proxy itself which will act as a go between and communicate with the server. It’s named “proxy” due to the same appearance like a VPN or a Virtual Private Network.

However, an outbound proxy server may not be so important for you at all. But, this field also entrusted by some SIP clients and providers. If you need to configure your clients but you didn’t get the proper settings from your provider, this can be complicated. Since an outbound proxy server would just be a waste when making use of a STUN server, you don’t need to configure it at all.

Visit your provider’s website (Internet Call Services) and spend your time on it to search for the information of what your proxy settings are. Or simply call your SIP provider. They will give you the details of how to automatically configure the VoIP phone of your clients.

VoIP Security

The industry of VoIP has matured greatly within the last decade. Most business organizations currently adopt this technology which was previously only used to make free phone calls by the consumers. Nowadays, VoIP is going to the stage where it is replacing traditional telephone systems. In advance, it was only an alternative among numerous communication channels.

In fact, the huge growth of VoIP system also catches the attention of hackers. Most reputable VoIP vendors have emphasized the necessity for organizations to require a better consideration for their security policies due to several high-profile attacks. Most of them need security analysis tools, as the intensity and frequency of such attacks has increased. Many network administrators lend a hand to assist their service providers resist fraud and other attacks.

Operators have task to quickly respond and provide professional estimation reports for implementations of VoIP.  Security assessments and deployment costs are usually bundled together which cost tens of thousands of dollars. The security would never be breached, if the security assessments have been undertaken at regular intervals. The services usually include various devices on a comprehensive review of the network as well as testing the security protocols and firewalls reliability and analyzing system architecture.

But, all of these security assessments will create a new question. Is it really important for the customers? Or, is it just being used as buzzword to promote carriers’ services? The answer of those questions depends upon the complexity and size of specific implementation of VoIP on each company.

The security reports aren’t needed on small and medium businesses that have installed and subscribed VoIP. The provider has responsibility to maintain secure networks, since they are managing the service off-site. Many of their clients cannot do apart from making sure the employees are not compromising the accounts, and keep the physical devices safe.

However, the huge benefits are waiting for some organizations that use their own IP PBX with a SIP trunk. IT administrators often need perspective of the outsider due to their limitations to see the weaknesses in their own system. In other hands, there were vulnerabilities that occurred during the implementation phase or there was not any sufficient importance that given to the security. Hackers can take advantage of any holes in the system before they had patched, in accordance to analysis from a professional.

Many of advantages that you can get from consolidating data and voice traffic onto the same networks. However, it invites new threats though. If the organizations do not want to meet the risk, they need to improve their performance in managing and identifying their networks.
