tIPicall Sip Trunking

tIPicall SIP trunking is built on the TATA Communications Ltd global SIP network providing the highest quality of voice across a tier 1 carrier at very competitive rates.

There are a number of functions and features which process calls in the PSTN. What SIP focuses on is a signalling and call set-up protocol for IP-based communications and SIP has been designed to allow functions and features to be built in via Proxy Servers and User Agents. These features allow telephone-like operations such as dialling, causing a phone to ring, ring-back tones and line busy signals.

Whilst the terminology and implementation of the SIP world is different to the way traditional calls are set up, the end results for the user are very similar.

SIP allows for much more cost-effective voice communication solutions and also provides additional features that ISDN and analogue lines cannot deliver.  While a SIP trunk is an alternative to an ISDN channel, as a tIPicall customer, you will have the flexibility to combine the number of SIP trunks and telephone numbers/DDI ranges you need.
 

What is SIP Trunking?

PSTN PhoneSession Initiated Protocol - or SIP - is the latest technology in Voice over Internet Protocol (VoIP) which savvy companies deploy in order to keep their telecom costs low.

Telephone calls have traditionally been made on the Public Switched Telephone Network (PSTN), an infrastructure made up of copper wires and dated switching equipment.

SIP provides access to and from the PSTN over the Internet Protocol (IP), an alternative method of routing your calls which allows greater flexibility of service and lowers call costs by replacing the traditional fixed lines with PSTN connectivity via a SIP trunking service provider.

Using the Internet means that savings can be passed onto tIPicall customers, as we have no other phone networks to pay, and line rentals for SIP trunks are significantly cheaper than standard analogue or ISDN connections.

SIP trunking also allows the distinct advantage of enabling a business to move geographic area but take their existing telephone numbers with them.

tIPicall provide a cost-effective, quality telephone service via SIP trunking through a Public Branch Exchange (PBX) to your offices or individual handsets.
