Hi,

I have a VOIP-GSM 16 port Dinstar gateway installed. It has its local IP, SIM inserted and receiving signals but somehow it is not getting registered with Freeswitch as external profile. 

I have tried all the things found at different sources such as :

https://wiki.freeswitch.org/wiki/Dinstar_GSM_gateway_FreeSwitch_HowTo

http://www.voipon.co.uk/documents/DWG_with_FreeSwitch.pdf

but no luck :(

Error at console - Failed Registration with status Request Timeout [408]


SIP trace is as follows:

Freeswitch Server IP - 192.168.2.71
Gateway IP - 192.1.68.2.69
