Hi,
I've created SIP Trunk between Yeastar TG-100 GSM Gateway and Cisco CUCM.
TG-100 ip address is = 172.68.9.41
Cisco CUCM ip address is = 172.68.9.31 (extension number is 10xxx)
In TG-800, i create two call route, one for Cisco to GSM and other for GSM to Cisco.
VoIP Phones behind CUCM (10xxx) can make calls to GSM numbers (+62821xxxxxxx) through TG-100 successfully.
But when doing call outside office to GSM number at TG-100, i could get the Cisco CUCM tone but when dial the extension number, nothing happens, until call terminated.
Could anyone give me a hint what to check at Cisco CUCM to might be the culprit to this problem ?
Thanks.

I finally solved it.
So, after i put the CSS as recommended by Nashaatmusa, i also create Route List, Route Group for this SIP Trunk and edit the Trunk Security Profile as attachment.
I do reset at the Trunk, SIP Trunk Security Profile, and suddenly it all works.
Thank you Nashaatmusa.

Ok, so i put the CSS in place, apply config. But still same result, i got Cisco CUCM tone but no other response until call ended.
I attached the Cisco CUCM trunk config i modified, and also below is the log from TG-100, maybe there are something in there, tbh i don't really understand the information on the log
