Hi ALL,
We have integrated Skype with Asterisk (skype user id:- rexesbposolutions). Each call which is coming to skype account is getting transfered to Asterisk Queue. It has following two cases:
case 1: When we call from normal skype account to skype account (rexesbposolutions), everything is working fine.
case 2: This skype account (rexesbposolutions) has been assigned with a online virtual number (00 44 20 **** ****). If somebody dial this number from their landline/cellphone, call is transfered to Asterisk queue but it shows some problem related to G729 codecs. following are Asterisk CLI log:
