Subscribers can be very grateful to having SIP telephone number facilities as it helps them in accessing your service easily. Moreover, you can enjoy better services like free VoIP calls wherever you are, whenever you want and without paying anything extra. Be in touch with your friends and relatives residing in other countries by availing a SIP number from which you can make and receive calls in the country they’re from. Thus, you can contact them at any time and stay in touch with them freely. You can avail a large number of benefits by availing a telephone number with a SIP enabled facility from a telecom company.
SIP, Short Interval Protocol, is a type of internet phone service that provides you with a dedicated number that can be called in an instant from any part of the world. This can help you in calling many people, regardless of the location. It’s like you’re talking to them from across the globe! SIP is also known by various other names, including IP telephony, session Initiation Protocol, session resumption protocol, and hop-by-hop protocol.
SIP session description protocol is a type of internet phone service. It uses the SIP protocol for establishing a session, transmitting data, controlling the session, resolving resolved protocol values and handling return data. The most useful feature of SIP is its ability to negotiate gateway bandwidths and digital phone lines, and for using MPLS (Multi-Layers Subnet) technologies. For small and medium sized businesses, SIP allows easy portability and eliminates the need for dedicated IP phones.
To help users dial numbers in different domains and countries, there are two methods to configure sip number normalization. First is the so-called domain dialing method, which allows a user to dial a number in a domain and use that number in other domains and countries as well. This feature is useful for dialing local numbers or toll-free numbers. The second way to configure sip normalization is to configure the session agent configuration.
Presently, there are two types of sip trunking providers – traditional and IP trunking providers. In the case of traditional sip trunking, a business simply needs to buy a connection from a sip trunk provider and install the plug-in. The plug-in will then be responsible for forwarding the calls to the right destination. However, the cost of this method is the major drawback of sip trunking.
IP trunks are much more reliable than traditional sip methods. However, the cost of IP trunking can be rather high. The good thing about IP trunks is that it has been set up on the backbone of the network. Unlike traditional setups, IP trunking does not need to connect every device to every router. Instead, there is a single central IP network that contains all IP devices that are part of a company’s whole network.
A major disadvantage of IP trunking is that it limits the types of calls that can be made from a sip provider. In particular, IP trunking cannot make conference calls because it uses the same IP address for each call. If a call is made from a computer that uses an IP address but does not belong to the company’s network, the call can end up using the host’s IP address, and thus will incur long-distance charges. The main disadvantage of using this type of system is that it can be very expensive. In addition, a company that uses IP trunking must pay for every outgoing IP phone call, even if no calls are made.
On the other hand, virtual numbers work differently. Instead of using an IP address, virtual numbers use a unique numerical representation that is difficult to track. A virtual number works just like a telephone number – the phone number is replaced by a unique address, which can then be traced back to its owner. Virtual numbers are typically used by companies that have branch offices in multiple locations instead of a single office location, which make it cheaper to maintain.
