So what you are saying is 3CX does not support group SMS at all if external numbers are involved?So the group is created externally and is pointing to this DID.
This is though expected as all externals will always point to the same destination.
Thanks. I also found this post. https://www.3cx.com/community/threads/group-sms-capability.118685/I believe the answer is in the below post:

That sounds like it would be more trouble than it is worthHi @lritpeter, we do have API/Zappier available that you can use to use to send to more than one recipient but those messages will not show up as outbound in the 3CX, if they respond and the webhook is pointed to 3CX then it will start start a new or continued convo in 3CX.
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
