Advantage & Disadvantage sip trunking

Advantage & Disadvantage Sip Trunking - SIP Trunking is a direct connection between our organizations with an ITSP (Internet Telephony Service Provider). With SIP trunking we can use VoIP (Voice over IP) outside the internal network without requiring an IP-PTSN gateway. Surely this will facilitate and minimize the cost of doing the design, operation, maintenance, and upgrades.

The term 'trunk' in SIP trunking, is a virtual connection between telecommunications systems. The connection can be through a special path to SIP trunking, or a special line for SIP trunking and other IP traffic, or can also be via the Internet VPN.

The advantages of using SIP trunking, among others, as follows:

     1. Reduce the cost of long distance service
     2. Eliminates IP-PSTN gateways / PBX
     3. Eliminates redundant network
     4. Eliminate the cost of the subscription BRI and PRI
     5. Expand the capabilities of Lync Server with new services from ITSP 

Comparison of SIP trunking connection type, as follows:

Connection Type	Advantage	Disadvantage
Special lanes (leased line) without other traffic	The most reliable safer does not require vpn call capacity highest-carying	most expensive
Special  lanes (leased line) shared with other IP traffic, often using MPLS	safer does not require vpn	Very high IP traffic can cause interference with VoiP, unless VoIP traffic is given priority
Public (internet)	cheapest	less safe require VPN less reliable the capacity of the lowest call-carying
