== Overview ==

The Technicolor DGA0122 and DGA4134 both have two analogue telephone ports, AKA ATA (Analog Telephone Adaptor).

These can be used to connected a 'normal' analogue phone and then the router can be configured to make/receive calls over VoIP.

[[File:BT-RJ11.jpg|200px|thumb|RJ11 to BT adaptors are required ]]

== Phone Adaptor ==

The ports on the router are RJ11 and usually telephones have a rectangular BT style plug - in which case a RJ11-to-BT adaptor is required. The DGA0122 doesn't come with any adaptors but the DGA4134 comes with one. These are available to buy from A&A.

The adaptor is effectively providing a BT Master Socket for phone(s) to be plugged into. It should include a bell capacitor for maximum compatibility with UK phones. Many modern phones don't require a bell capacitor, but those which do won't ring without one.

== Router Configuration ==

## Click Save

You can configure further things, such as a second VoIP account and set which account uses which phone port etc. Note that the configuration requires that a second VoIP account uses the same server as the first account.

The source address will be the single IP address of the PPPoE link. Sadly it doesn't seem able to use the router's PPPoE IPv6 address (in the 2001:8b0:1111:1111:0:ffff::/32 range).

== Codecs ==

Login to the router as user ''engineer'' with the admin password. Click on the ''Telephony'' tile and then ''show advanced''.

Change the Voice Audio Codecs to make PCMA the first choice.

== RTP Ports ==

By default the RTP port range is 40000-65000. You may wish to restrict this (for example, to match firewall settings). This can be done by an ssh connection to

the router as the ''engineer'' user and admin password, then issuing the commands e.g.

set InternetGatewayDevice.Services.VoiceService.1.VoiceProfile.1.RTP.LocalPortMin 5000

set InternetGatewayDevice.Services.VoiceService.1.VoiceProfile.1.RTP.LocalPortMax 5098
