Hi

Our client is using CME 4.1 with ISDN E1 Pri connected to PSTN, the client bought a software to record all calls both internally and externally. When calls are done internally they are recorded perfectly, but calls to/from PSTN are recorded with a lot of noise, the software provider said that they need U-LAW codec to have a noise free recoding.


I changed the recording on ISDN interface using the Compand-Type to U-LAW, doing so degraded the whole telephony system quality.


is there is a way to convert to make U-LAW the global codec used by CME.


Thanks a lot

Im not too sure if this might be the correct answer but you can change incoming call codecs via the dial-peer voice X VOIP command. and codec GXXX


i think by default its G729.


again not too sure but im sure somone with a bit more experience might be able to shed light


good luck

maybe the software provider should take a look from thier side?....i did a install about two years ago with CME 3.X. the recording software we used was Calrex and it still works properly. The CME was setup without any adjustments.


Note: this solution was with FXO ports though.
