Q. Asterisk RTP port range problem after sometime usage of day or long?
A.

By default, ooh323 uses H.225 setup channel port range from 12030 to 12230. The default range for RTP in Asterisk's rtp.conf file is to use 10000-20000. So after you have been using asterisk in a production environment for some time, the RTP port usage clashes with the H.225 setup, which subsequently fails.

Workaround: Change port range in rtp.conf or ooh323.conf file.

The ooh323.conf file uses h225portrange=12030,12230 option to set the H.225 channel port range.
