Virgin Meda VMDG280 And SIP Asterisk


We’ve got a client with a Polycom IP331 on Virgin Media behind a VMDG280 Router. Asterisk is in a data centre with a public IP.

According to the link below, there seems to be a fault with the router that blocks all SIP but the client doesn’t want to change it.


Looking at the SIP DEBUG on the server, Asterisk receives the packets from the IP331, but the Polycom doesn’t receive anything back from Asterisk. Port forwarding doesnt seem to help and theres no SIP ALG options on the webadmin of the router.

Has anyone successfully connected a SIP endpoint (Polycom IP331) with Asterisk on Virgin Media?

Kind regards,
