Skype VoIP LAB, a Gotcha-Free integration guide for Skype for Business + Asterisk + Google Voice

VOIP LAB DAY 13 Adding Skype for Business 2015 Part 3

We are almost there. Last time we successfully made call from soft phone connected to the PBX to Skype user. Now we need to be able to make call from Skype to PBX and to the PSTN. If you followed the instructions so far, we made SIP port on PBX set to 5060. We need to change the port for Chan_PJSIP to something else so the Chan_SIP can listen on 5060 instead of Chan_PJSIP. Follow the below instruction to change the port used by Chan_PJSIP. 

Open your Incredible PBX web admin and navigate to Setting, Asterisk SIP Settings.

Click on Chan_PJSIP. Change the port 5060 to 5062.  Submit and Apply Config. 

After you change the port on Chan_PJSIP, you need to reregister your soft phone with correct port as below.
