(Codecs and RTP ports) |
||
|
You can configure further things, such as a second VoIP account and set which account uses which phone port etc.
== 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.
InternetGatewayDevice.Services.VoiceService.1.VoiceProfile.1.RTP.LocalPortMin 5000
InternetGatewayDevice.Services.VoiceService.1.VoiceProfile.1.RTP.LocalPortMax 5098
