I have an issue making 2 or more calls within a short space of time between two phones, one native IP behind a CME running 220.127.116.11 and the other behind a 2811 router with a basic H323 voice gateway configuration.
The (edited) configs for each end are attached. The first call from one phone to the other (or using csim) goes through fine. However, once the call is ended, if a subsequent call is made within a minute or two afterwards to the same phone (or a phone via the same destination gateway), the call fails and I get the following debug output from h225/h245.
