[Asterisk-Users] SPA-3000 and quiet voicemail

[John Goerzen]

Hi,

I have a Sipura SPA-3000 for access to my standard analog PSTN line.  I
have the SPA-3000 answering and then directing all calls into Asterisk.

This setup is working fine for everything except voicemail.  Most, about
2/3 or so, of messages left come across very quiet when the voicemail is
played back.  A regular conversation with these people, regardless of
the phone used on my end, works just fine.

I did some googling and came up with two links of similar problems, but
only for people that are using Zaptel cards:

I can't figure out what is going on with the SPA-3000 setup I've got,
and it's really odd that everything except voicemail works perfectly.

Suggestions would be most welcome.

Thanks,
John
