Harald Welte gerrit-no-reply at lists.osmocom.orgHarald Welte has submitted this change and it was merged. ( https://gerrit.osmocom.org/9260 ) Change subject: vty: clean up rtp port-range command ...................................................................... vty: clean up rtp port-range command The VTY command that sets the RTP port range does not check if the data entered by the user actually makes sens. Also it allwos to configur a range that starts at 0. - Make sure 0 can not be used as start or end of the range - make sure the end port number is always greater then the begin port number - Autocorrect uneaven port range beginnings to one port number before to ensure the range starts at an even port number - Autocorrect even port range ends to the next odd port number to ensure the range ends at an odd port number.
