What for? SER does support 3rd part call control already, because it is just signaling for SER. SER as a proxy does not care who is talking to whom. Or who controls whom. E.g. if their are two phones and a media server in a 3pcc scenario, there is absolutely no need for special 3pcc support in SER. Only if SER should be the one of this 3 parties which controls the call between the two other parties, that would require special support. Nils On Saturday 02 July 2005 17:40, harry gaillac wrote:
