TelephoneIntegration Client supports SIP Client

This article outlines how to connect your phone system with TelephoneIntegration, if no TAPI driver can be found. If you cannot find a proper TAPI driver for your VoIP phone system, but his VoIP phone system is based on SIP, then you might find the SIP Client wrapper really helpful.

Requirement: TelephoneIntegration (TI) Client v 7.109 or higher

Definition of terms:
TAPI = Telephony Application Programming Interface
VoIP = Voice over IP
SIP   = Session Initiation Protocol

How do you know if the SIP Client wrapper is the right tool for you?

A) Your phone system bases on VoIP ( SIP). 
You should be able to make phone calls over any other SIP softphone like X-Lite, Zoiper, Linphone, MicroSIP, … all you need to know is 

  • your SIP Server domain
  • your username and
  • your password.

If you can give and receive phone calls (by dialing E164 phone numbers and not only SIP addresses) with such SIP softphones, you could use our TI Client with our already built in SIP Client wrapper. That way, our TI Client becomes the SIP softphone.

The following VOIP SIP SDKs are compatible with PBX systems:

  • Cisco UCM
  • Cisco CME
  • Asterisk
  • 3CX
  • SwyxWare
  • Aastra Mx-One
  • Kamailo
  • FreeSwitch
  • OpenSIPS
  • FreePBX
  • SipX ECS
  • Trixbox
  • OpenSER
  • PBXpress

How to start the SIP Client wrapper?

1) Please open your TI Client settings.

2) TI Client (version 7.109 or higher) offers a SIP Client configuration page. To open the page, navigate to the SIP Client-tab (see figure 1) and insert your

  • username (your current extension number)
  • password and
  • domain

Figure 1: SIP Client configuration page 

Transport type and SRTP mode can be set as they are now.

3) Save and close the settings and restart TI Client.

Please keep in mind that the SIP softphone Client is completely separated from your current softphone Client! This means, if you receive an incoming call, all hitherto existing Clients will react. If you accept the call with your previous systems, TI Client will show the accepted call as missed call.

Please note: To avoid this behaviour, it is of upmost importance , that you accept all calls with your TelephoneIntegration Client.
