Our SIP Trunks

Not a lot of people have heard of the term ‘SIP Trunks’.

So what is it?

SIP Trunks is a solution that COMTALK offers and provides.

It connects your PBX to your existing telephone system via the internet. Also called VoIP (Voice Over Internet Protocol).

If you currently use old ISDN lines that connect your current existing PBX system with your telephone solution. We can offer that you keep your existing PBX System.

We can replace your costly ISDN with a SIP Trunk in order to convert it in to VoiP.

A financially viable solution that is termed SIP hosted PBX

Some of the many advantages of using SIP Trunks instead of  ISDN are:

COST: Your expensive ISDN solution will be replaced by a SIP Trunk.Which in most cases, equals to a significant cost saving solution with your monthly telephony bills.

REQUIREMENTS: The only requirement for switching to a SIP hosted PBX is that your current PBX system supports SIP trunks. This can easily be established. As not all PBX systems support the mentioned.

SOLUTION: We offer the opportunity to purchase an ISDN to SIP adapter too, if required. Allowing for full compatibility between your system, and the SIP Trunk.
