Hi
I am new to Draytek. I bought a new 2830vn plus for our fibre connection. It goes through the wan 3 Ethernet port via a open reach modem.

We have a SIP phone system but the Draytek is blocking incoming calls. We have created the open ports as required etc. If we dial out on the phone system and then immediately dial in, it works, before the NAT has reset I guess.

We then got the phone company to have a look at it and they brought a 2830n model and set exactly the same configuration and it works fine.

The 2830vn+ has VOIP facility built in.. does this have something to do with my problem? Does something need to be disabled for us to use our own voip system via SIP?

Thanks in advance

Ash

If assigning a unique IP to each SIP device is not a possibility, try setting up your SIP devices to use an outgoing proxy.

Hi

Outgoing calls work.. its the incoming phone calls that don't. We only have one public ip address pointing to the internal phone system ip.

As I said it works fine with the standard Draytek 2830n router with exactly the same settings.

Thanks
Ash
