| I have seen one way speech problems in the Media cards that seem to grow over time.
I would do everything that Slagburn suggest.
Also can you narrow it down to sites or types of calls, such as ip phone to ip trunks to pstn. You maybe able to narrow it down by tracing calls in ld 80.
You have alot of placing that could be causing issues.
I have also seen subnet mask being set wrong in one interface cause 1 way speech problems.
Hopes maybe this will give you someplaces to look |
