Hey,
We have a DFL-210, working fine for many years. But we have a problem setting it up for our new VOIP-system.
The DFL-210 is running firmware 2.27.03.25-14787. We have a Asterisk server connecting to an external SIP-provider. We set up our DFL-210, following the example and directions in the manual. Outgoing calls are working fine. Incoming calls are forwarded to the Asterisk server, but on a random port in stead of the 5060 port. When tested without the firewall, calls do arrive on the right port.
Anyone else had this issue? Is this an ALG issue and is there a way to force the use of port 5060?
Regards,
Lieven
