PRI crackling and noisy

Scelo

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

 

Configs:

Issue was on Telco side, they had to move the PRI to a different port on their end and that fixed the problem.
