Greetings,
i'm experiencing some audio quality issues on my PRIs, started recently and nothing changed on our enviroment - below is what is experienced and Telco says they see no errors on their side (they reloaded and still the issue continues):
- Crackling noise on inbound calls (none on internal calls)
- When far end is silence, sounds like they're watching a TV though they report to be alone in the room (more like crossed lines when there is silence on the call).
Reaction:
- First rebooted the GW to no luck
- Added and removed commands below on voice ports, no change:
compand-type u-law
bearer-cap Speech
**When we add on all voice-ports we are unable to make calls
