Abstract
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 RTC client and the RTC server can negotiate during the establishment of the RTC communication connection which of the ports of the firewall are required for the data packets to be exchanged via the RTC communication connection, wherein they use at least one standardised message element as a component of the proprietary RTC signalling protocol, with which information relating to the ports to be used can be found by the firewall.
