I have a customer that is using the Advitel MOH server to broadcast real time news updates, events and weather forecasts (etc) to callers placed on hold. I have connected the headset jack on the server to the mic input on the Cisco USB MOH card and the quality is very poor. The "esses" hiss and there is a lot of crackling. I guess this is due to input/output being balanced/unbalanced. Has anyone successfully attached another make of USB card that has a line in port rather than a mic in.
This is all sorted now but thanks for your comments. It transpired that the problem was with the recorded format of the original .wav files. The provider of the MoH files record their files in high quality format and then use EQing to compress / resample to a lower quality and that seems to be whats causing the problem. I created some of my own .wav files in the correct format for CUCM from the outset and they were fine.
