Can't send RTP stream to 0.0.0.0:0 destination unreachable

[decorsign]

Since we have changed the Trunk to a different platform, we see a strange problem regarding missing inbound RTP with inbound calls on GIGASET N300A devices only!

This is the error 3CX states in its server event log: 06-mrt-2017 20:24:18.751 [MS004000] C:7.6: (ACTIVE): Can't send RTP stream to 0.0.0.0:0 destination unreachable

When calling outbound, everything works fine.
When picking up on Yealink cabled phone or Cisco cabled phone, allso everythings works fine.

Can you please advise?

do you use stun on the device?

Hi This issue has been resolved by just upgrading v12.5 to v15. After this, no problems so far!
