Thank you George.
Using slin16 instead of generic slin resolved the issue.

We tell asterisk to use the slin format for ExternalMedia. However, the unicast channel is selecting ulaw formatand the RTP data is indicating it’s ulaw format.
Anyone know why ulaw format would be on chosen?
What do your ARI requests look like? Are you just requesting "slin" or one of the specific variants?
