Anyone has experienced metallic sound in various sites connected to NSN eBSC BR9? All tests are done, it is neither about transmission erros, nor hardware fault, nor RF interference.
When we change the site to another type of BSC (not eBSC), the problem disappears by magic.
If anyone had the same issue, and how they did to solve this, thanks.
is it happening with all type of phones? It happens in our network (ALU) when the called party has Nokia phone then we experience metallic (sword) sounds. Couldn’t solved, even by ALU TAC. So, check that, with different types/models of phones.
