[OpenSIPS-Users] MediaProxy 2.3.10: T38 Fax using zoiper 2.14 for MAC

[Mike O'Connor]

Hi All

I've been trying to get T38 faxing going and for testing I've been using
the t38 client in zoiper and asterisk 1.6.

The process is that the call goes to opensips which has a usr_pref which
indicates this is a fax number, the call is then forwarded to Asterisk.

Asterisk answers the call after letting it ring for a while, once
answered it call fax_receive.

Zioper then does a re-invite with the t38 headers at that time the
mediaproxy report the error below.

Does this look like an issue with my opensips configuration, a bug in
mediaproxy or an issue with Zoiper ?
