I have one TDM04b(4FXO) that BTW came with a broken module and I'm sending the module to RMA. The other channels work well with one phone but with some specific brand/models don't work.
For example: Sharp CJV-743W http://www.sharp.co.jp/products/cj/index.html#cjv743w Using the cordless phones or not, the sound in some calls is very low and sometimes is like when you put a shell in your ear. Other calls work perfectly. So, the problem is intermitent but with a big frequence. I did already some measures: 1) All the phone wire in the building was changed 2) I put the boards in another machine 3) The boards are not sharing IRQs 4) I'm using 2 wire cable 5) I already tried to change rxgain to several values 6) I have two of those Sharp phones with the same problem and I trashed already some other thinking that it was a phone problem. 7) I am using the latest CVS zap and * 8) I am using aggressive echo cancel with the new algorithm This machine has 1 TDM40b and 1 TDM04b and actually I don't know if it's a problem in one or other. The phones directly connected to the line works perfectly. Did anybody have a similar problem?
