A method for exchanging compression/decompression dictionaries, and a communications node, which comprises a client module issuing and receiving messages, a compression/decompression module for compression/decompression of messages issued and received by the client module, a first dictionary for use by the compression/decompression module, and a second dictionary for use by the compression/decompression module. When the client module determines a sequence based on which to exchange dictionaries with one or more peers (e.g. a P-CSCF), it creates the first dictionary comprising at least one prioritised type of message and sends the first dictionary to the compression/decompression module, which stores the first dictionary and further sends it to at least the peer node.; Still based on said determined sequence, the client module further creates the second dictionary comprising at least one other type of message, sends the second dictionary to the compression/decompression module which stores it and further sends to a peer node.
