[asterisk-users] Asterisk "we couldn't allocate a port for RTP" errors

[David Cunningham]

Hi Joel,

We see some channels stuck on the StopMonitor application which could be
the cause, though there are only about 20 of them.

An Asterisk restart is the immediate cure for sure - we were hoping to
identify some cause in order to prevent a repeat.

Thanks very much for your advice.
