Potential problems with codecs negotiation using SDP protocol
Original language description
Modern voice communication networks are usually built as converged networks enabling voice and data transfer upon using an Internet Protocol (IP). Voice services further require a signalling protocol for their work. Nowadays, the Session Initiation Protocol (SIP) is the most popular signalling protocol used in these types of networks. Compared to traditional telephone networks, voice communication over the IP protocol enables a choice of a codec. The codec that will be used to communicate is negotiatedby terminals or gateways using the Session Description Protocol (SDP). It is transmitted in the body of the SIP protocol. If respected the rule that each communicating device must support the G.711 codec, it should not lead to a situation where the communicating parties cannot agree on the codec. In practice, the situation is quite different. In many cases, it is not possible to establish voice communications because of unsuccessful negotiation of the codec. The following article briefly
