Hello All, We had several GSM Gateways (couple of Dinstar DWG Series) and triying to move from Asterisk to Freeswtich. My freeswitch setup was in virtual Machine in ESX Server at 10.10.1.71 And My Dinstar GW was on 10.10.1.109 My freeswitch dial plan based from standart setup but I delet most of default.xml. I can made call from gw to gsm phone via originate and or using softphone. However I cannot hear any sound. What can be wrong, aslo could you suggest me good debuggin practices. My Best Regards. Here my Silly debug log. Some how it goes sleep when I press to accept call button Dialplan: sofia/internal/sip:1001@10.10.1.36:31292 Action transfer(7001 enum) 2014-10-22 14:20:32.709543 [INFO] switch_channel.c:3062
