MOH bad quality

[cordas]

I have a 3300 with 7.1 and I'm having problems with the MoH, some calls have a very bad MoH sound (when they are on hold) and others have normal MoH.
Is there any thing I can check to solve this?

Best regards,

Rui Cordeiro

What is your music source? I find that a radio can be problematic in a phone room with equipment that generates interference.

I'd recomend to use an external source such as CD whenever it's possible. Embedded MOH quality suffers once in a while and seems that's design issue. I've got multiple embedded recordings which play ads for different divisions and once in a wile people say that it souns horrible but at the next moment everything is fine and I cannot reproduce it. External source is always nice and clean.

Thanks, I'm using embedded MoH.

I'll try to use an external source.

check the properties of the wav file you uploaded. The help files quote 8Khz, 8 bit and mono, they also state a-law or u-law.
I had a problem recently where the file was a-law, i changed to u-law and it sounds perfect now....

Also be mindful of the fact that "music" utilizes as much or more network bandwidth than a voice conversation. Typically how many calls are on hold at once? Are they "holding" across IP trunks? In a bandwidth-constrained system disabling the Multiline set Music feature in COS can also relieve such congestion.
