IP Office SIP trunk

SIP trunks are becoming more and more relevant, because older PSTN connections are on the decrease. The wide variety of different providers and several call types brings a much higher comlexity of the configuration along.

Working out the needed configuration to cover all the needed call scenarios can bear a big time investment.

That’s where I can help you out!

I offer you to create a reliable configuration based on your need or on those of your customers.

To ensure that all relevant call scenarios work as required, I will test all varieties after the configuration is done and document them.

I will do the job for a fixed price so that you have a reliable basis for your cost calculation.

I will do the following tests:

  • Inbound call to an extension
  • Inbound call to an extension that is forwarded to voicemail
  • Inbound call to voicemail or an auto attendant
  • Outbound call to an external target
  • Outbound call from voicemail (voicemail callback)
  • Inbound call to an extension that is forwarded to an external target
  • Inbound call to an extension that has mobile twinning enabled

I will document the tests and send you the results.

Different types of connection are possible.

A simple connection of IP Office to a SIP trunk:

IP Office with SIP trunk
IP Office with SIP trunk

A connection of IP Office to a SIP trunk using Avaya Session Border Controller:

IP Office with SIP trunk over ASBCE
IP Office with SIP trunk over ASBCE

The connection of two IP Offices to two redundant SIP trunks:

Two IP Offices with one SIP trunk
Two IP Offices with one SIP trunk

There are further scenarios with redundant Session Border Controllers possible.

Even the mutual configuration of SIP trunks and remote users on a single system with or without Session Border Controller can be done:

IP Office with SIP trunk and remote users
IP Office with SIP trunk and remote users
IP Office with SIP Trunk und remote users über ASBCE
IP Office with SIP Trunk und remote users über ASBCE
Two IP Offices with SIP trunk and remote users over ASBCE
Two IP Offices with SIP trunk and remote users over ASBCE

I am looking forward to prepare a quotation about the configuration for you.
