my customer want the SV8100 system play some advertisement audio to their customers when they call in.
I mean when somebody calls in, he/she will hear "This is xxxx, blabla..." instead of boring "dudu, dudu" ringback tone. when someone pick up the phone, conservation begins.

I have tried in 22-14 VRS waiting message, but the question is I could just upload a .wav file up to 1MB, the file customer provides is a 5MB MP3 file.

any suggestion?

you seem to have answered your own question ?

If it is just for MOH then a MOH player like a MP3 is required with a LIU

if this is for VRS auto attendant you mean (as is done professionally not just someone onsite talking into the phone ) then it needs to be a specific format thou for the system to accept it

if you mean you want it like caller tone - as in someone rings your mobile and they hear music instead of ringing the system can not do that. My best option here would have the calls to VRS yes 22-14, then have a period of dead silence in the VRS message, then have MOH playing between the VRS messages , have a delayed to the second message of say 30 seconds, then the second VRS message will play. Then they would hear a second of nothing, then straight to music.

Replacing ring tone with a message wouldn't be allowed in Oz anyway. The ACMA would drop on you like a ton of bricks if you did/could. You have to be careful even sending ring tone to an incoming caller too, the caller has to be aware when charging starts to give them the option of hanging up. There was a big issue some years ago where certain telephone systems with call queuing would put you into the queue, tripping charging, but then playing Australian ring tone so the caller didn't know they had started paying for a call which hadn't actually been answered.

I would be steering well clear of this one if I were you!

Thank you, bully.

We have found 2 ways.
One is to compress the music to 8 bit x 8 kHZ, so the total music is about 125 seconds. Uplaod it, point 22-14-02 to this message, it works.

The other way is what you said, a blank message to 22-14-02, and set MOH/BGM as the internal music in 22-14-06. So after a short silence, it goes to MOH/BGM.

Thank you again for your reply.

yes, you are right. but some customers want their advertise to be sent out to their customers.
maybe some will hang up the call if they don't like it.

just like me, if i will hang up immediately if my call goes to someone's voice mail.
