Got a strange issue with a 710 running Firmware 126.96.36.199, connected to DIDWW.
When I hang up an outbound call, the dialled phone continues to ring until answered. I tested with X-lite and it works perfectly also the D715’s don’t seem to have the issue.
The provider says the BYE is not being sent until the call connects/times out.
Is this a bug or is there a setting I can change?
Things Already Tried...
Set ip_frag_enable = on (No Change)
Set ICE to Off (No Change)
Disable RTP Encryption (No Change)
Any ideas appreciated…Thanks In advance!
do you use stun? can you check it?
We opened a ticket for that issue.
Turns out there was UDP loss, adding the line email@example.com;transport=tcp into the Outbound proxy field resolved my issue.
Many Thanks Norman!
