Abstract
The invention relates to a telecommunications assembly () and a method for traversing an application layer gateway firewall () during the establishment of an RTC communication connection between an RTC client () and an RTC server () using a proprietary RTC signalling protocol, wherein the firewall () has no specific knowledge of the proprietary RTC signalling protocol. The method comprises the following steps: the RTC client () and the RTC server () negotiate during the establishment of the RTC communication connection which of the ports (P, P, P) of the firewall () are required for the data packets to be exchanged via the RTC communication connection, wherein they use at least one standardized message element as a component of the proprietary RTC signalling protocol, with which information relating to the ports to be used can be found; during the establishment of the RTC communication connection the firewall () detects, with the aid of the standardized message element, which of the ports (P, P, P) of the firewall () are considered by the RTC client () and the RTC server () to be necessary for the data packets to be exchanged via the RTC communication connection; and the firewall () opens and closes the required ports (P, P, P) in a dynamic manner according to the result of the negotiation.
