Codecs Supported

From VoIP.ms Wiki

Codecs are used to convert an analog voice signal to digitally encoded version. Since voice and sound as we hear it is analogue, it needs to be converted (or encoded) to a digital format suitable for transmission over the internet. Once at the other end, it needs to be decoded again so the other person can hear what you are saying.

We do support 3 audio codecs only: G729a, G711u (also know as uLaw or PCMU) and GSM. Their specifications are:

Codec : G722 Bit Rate: 8 Kbps Nominal Ethernet Bandwidth (Kilobits) : 64 kbps

Codec : G.711u Bit Rate: 64 Kbps Nominal Ethernet Bandwidth (Kilobits) : 87.2 Kbps

Codec : G.729a Bit Rate: 8 Kbps Nominal Ethernet Bandwidth (Kilobits) : 31.2 Kbps

Codec : GSM Bit Rate: 13 kbps Nominal Ethernet Bandwidth (Kilobits) : 29.2 kbps

These are specified on the Account Settings page.
