Hello, Currently, I faced an issue in setting up the outbound call from Freeswitch to PSTN via Dinstar GSM Gateway. My question is there any other configuration I would have to follow to make it works? Please kindly give advises. I follow this Freeswitch Dinstar How-To Guide <https://freeswitch.org/confluence/display/FREESWITCH/Dinstar+GSM+gateway+FreeSwitch+HowTo>. Since the tutorial is not working for the outbound call to PSTN, I followed the DWG_WITH_FREESWITCH.pdf instead. Unfortunately, both of them not working for me with outbound calls. I tried with the following configuration: *1. With Dinstar GSM Gateway IP* <extension name="dwg2008_gateway"> <condition field="destination_number" expression="^0(\d+)$"> <action application="answer"/> <action application="set" data="ringback=${us-ring}"/> <action application="log" data="INFO calling via gateway to 0$1"/> <action application="bridge" data="sofia/internal/0$1@192.168.7.137"/> </condition> </extension> *But this is not working, I got NORMAL_TEMPORARY_FAILURE.* Please see the dinstar log named* setup_1.log* *2. With GSM* <extension name="dwg2008_gateway"> <condition field="destination_number" expression="^0(\d+)$"> <action application="answer"/> <action application="set" data="ringback=${us-ring}"/> <action application="log" data="INFO calling via gateway to 0$1"/> <action application="bridge" data="sofia/gateway/gsm/0$1"/> </condition> </extension> *This is not working as well, I got NORMAL_TEMPORARY_FAILURE.* Please see the dinstar log named* setup_2.log* *NB*. The DID from PSTN to Freeswitch via Dinstar GSM gateway is working fine normal audio. I am able to provide the configuration of dinstar gateway as well if you might want to see it. Any solution would be really appreciated. Best regards, Chhorm Chhatra
