Static on VoIP calls

[Boomarang]

Scenario:

System A and B are both BCM400, 4.0, current patches. New installs.

System C and D are both BCM400, 3.5, current patches.

Calls between systems are routed over VoIP trunks, 24 trunks at each site. Customers at sites A, B, and C are complaining of "static" that comes and goes. There is no consistency in extensions called, systems called, nor time of day that the calls are made. No information from system D yet. I haven't been on-site to watch BCM monitor, so I don't know which trunks.

Where can static come from on VoIP calls? Virtual water on the channels?

Seriously though, I need help. Any ideas?

What the customer says is "static" may actually be amplified white noise. Make sure SILENCE COMPRESSION is set to NO. Also, give us more information.. ie: CODECS in use, have you implemented QOS? What about MEAN OPINION SCORES on each CODEC?

I would say you have a bandwidth / QOS issue but like DBrewsky has already suggested we need more info

additionally how are the site linked together data wise

If it not broke tweak it..

Resolution!!!

I just received a message from the customer who stated that they were having a problem with their T1's. They re-channelized them to allow more room for voice traffic.

YEAH!!!!!!!
