Basically, just connect the DrayTek's FXS ports to Analogue Trunk Line (FXO) ports on your PBX, and setup those ports as a separate trunk group. DrayTek have provided an example here
See http://www.draytek.com/user/SupportAppnotesDetail.php?ID=21
Note that this function does not apply to Vigor 2100V, Vigor 2500V or Vigortalk, which only have one FXS port. See http://www.draytek.com/user/SupportAppnotesDetail.php?ID=23
The VoIP configuration section in the Vigor VoIP routers allows you to choose a "preferred codec". Basically, if you don't want to use G.729a/b codec, you simply have to choose another codec. However, this is the "preferred" codec,...

Not every VoIP device supports every protocol.  For example G.729 and G.723 are licenced, and so some manufacturers have chosen not to include it - particularly in free VoIP software including X-Lite and asterisk. Fortunately the SIP protocol allows th...
This applies to Vigor 2100V, 2500V and 2700V models only. When you are on a call which is going through your VoIP provider, and there is an incoming call on the PSTN line, the Vigor's "Call Waiting" feature will play beeps to inform you of ano...
Call Forwarding allows incoming SIP calls to an FXS port to be redirected to another SIP URL. See here [http://www.draytek.com/support/support_note/router/application/voip/08.php] for instructions and example.  Note that incoming PSTN calls (through th...
There are several issues with Fax over VoIP, due to VoIP being optimised for voice signals (smooth wave) rather than data signals (square wave), with the result that we cannot guarantee results.  Given that most documents are generated on computers, th...
A misconception is that the Expiry Time setting dictates how long a VoIP conversation can last. That is incorrect. The expiry time settings indicates to the router how often it should re-register with the sip server. The expiry time setting on the rout...
DrayTek have VoIP versions of most of their routers, and the functionality differs. Basically, there are 3 groups: Residential models (Vigor 2100V, 2500V, 2700V, 2700VL) allow one telephone handset which can make and receive calls from VoIP and PSTN. Li...
This is probably because the VoIP Ports are Opened/Forwarded to the first device.  Check your router's NAT > Port Redirection and NAT > Open Ports configuration pages for entries containing TCP Port 5060. There are several NAT Traversal options (...
If you have a DrayTek router with a "V" after the model number (e.g. 2500V, 2600VGi), please refer to the page for the appropriate model for setting up the built-in FXS ports. If your DrayTek router does not have a "V" model number su...
You certainly can ! There are two techniques which can be used, and your DrayTek router supports both of them... STUN server method is much simpler, but requires that your VoIP device supports use of a STUN server. See your VoIP device's instructions for ...
It depends. If you are using the Open Ports method, you can only have port 5060 forwarded to one LAN device. You could use a different public port (e.g. 5061) forwarded to an additional VoIP device - but this will require that your VoIP Provider's SIP ser...
I think you have totally misunderstood what the Vigor's VoIP is trying to do. The Vigor's FXS ports are similar to a softphone, in that they both provide a user interface for making VoIP calls.  Where the softphone uses the PCs speakers and microphone,...
Yes, you can connect any standard phone (with an analogue interface) to either of the 2 FXS ports. If your phone can connect to the Telstra phone wall socket, then it can be used with a Vigor's FXS port (though an RJ-11 adaptor may be required if your pho...
There are several codecs with varying degrees of compression, with G.711 (no compression, 64kb/s) and G.729 (8kb/s) being the most commonly used. However the internet doesn’t provide a dedicated physical wire between the two endpoints to send the digiti...
What is DTMF (Dual Tone Multi Frequency) ? When you press a button on your phone it sends a combination of two audible tones (identifying the column and row of the key on the standard keyboard layout), which can be separated at the other end to determine ...
This can be achieved simply by using the VoIP > Digit Map setup. The following image shows a prefix "8" used to make calls via VoIP1 provider, and prefix "9" to make calls using VoIP2 provider. Note that the prefix "8" is stripped off (i.e. not sent to ...
From the Vigor 2800V's Main menu (down the left-hand side of the page), click on "VoIP" then "SIP Accounts" to display the SIP Accounts List page. Click the index "1" to ented or update the first SIP account profile (as shown below configured for SPANt...
Digit Map can be very powerful; however the documentation in the manuals is, err, minimal. DrayTek Vigor 2700V and 2800V models allow up to 6 SIP accounts (with different or same provider) plus PSTN (on 2700VL models only); which can be mapped to 2 tel...
There are several issues which can affect quality of On-net calls (SPANtalk to SPANtalk) including: Low bandwidth internet connection.  A 256/64 basic ADSL should be sufficient when G.729 codec is used, but if G.711 is used for a particular call then qua...
Check whether your router's firewall has Denial of Service (DoS) attack prevention enabled, and "UDP Flood Attack" in particular enabled.  If so, disable it and see if calls are still cut off. If this works, you may like to re-enable the UDP ...
A VoIP device digitises the voice conversation, chops it into packets, and sends the packets using the UDP protocol. If the VoIP device at the other end is using a packet size of 10ms, then you would be receiving 100 UDP packets/second just for one VoIP c...
If you are using a VigorTalk ATA, this problem is most likely caused by a compatibility problem with your ADSL modem or router. The modem is not correctly translating the outgoing SIP messages leaving your network, thereby preventing you from making a ca...
This is most often caused by the Expiry Time setting in your VoIP device being shorter than the Expiry time used by your VoIP provider's SIP server.  Background:  Unlike your Telstra PSTN line, a VoIP connection may not always be connected - such as t...

If I understand you correctly, you have several VoIP devices (eg PCs running softphones) and you want them ALL to be available on ports TCP 5060 and UDP RTP ports.  But when a packet arrives at the Vigor's WAN interface port 5060, which of the devices on...
There are a few mistakes that Draytek users encounter when setting up a VoIP account on their vigor router. The following are some common errors that have prevented Draytek users from "registering" their VoIP account with their VoIP provider's SIP Server....

Yes, if your router has two VoIP phone ports (e.g. Vigor2820Vn) you can make a call from one phone to the other locally - this is sometimes known as an 'intercom' facility. Lift the handset and dial 10# or 20# for the appropriate port. Do not set any d...

Before your Vigor router will make a VoIP call, it has to know that you have finished dialling the number. It does this by waiting for 3 seconds after you have finished dialling the number. To eliminate the delay press the # (hash or pound) sign on ...
Some Vigor routers, such as Vigor 2700V, Vigor 2710V, Vigor 2820V, etc., have two FXS ports, and each of the FXS ports has an internal phone number by default: * 10 for FXS1 and 20 for FXS2 - For Vigor2700V/VG, Vigor2710Vn 2820Vn * 01 for FXS1 and 0...

It has been found that with some phones (mainly Uniden) there is an extensive delay before the caller ID is displayed on the phone. The delay can be minimized by changing the Ring Pattern in the VOIP settings. Ring Pattern 4 usually gives the fastes...
When connected to some VOIP service providers you may notice a distortion in the voice quality when making phone calls. This often is due to the Codec used in the router phone settings. The default codec used is G.729a/b. If you have a low speed Int...
