[Asterisk-Users] Scrolling messages

[Joe]

Several times a day I get this meesage scrolling on one of our asterisk
boxes:

Mar 13 14:43:47 NOTICE[11264]: channel.c:1911 ast_read: Dropping
incompatible voice frame on Local/928 at sanset-d88e,2 of format slin since our

At first I thought it had something to do with the phones, but we changed
the phones, and we still get them.

There are only two codeces running on the box, alaw and g729. This box is an
external GW, it has softphones (iax and sip) connected to it as well as
hosted customers using Cisco 7940s and 60s.

If anyone has any ideas how to get rid of these messages, or why we are
getting them and ideas would be appreciated. We have several other asterisk
boxes running, and none of them have this problem.

Regards to all,
Joe
