[asterisk-users] Asterisk 1.8.13 / res_fax / res_fax_digium

[Eric Wieling]

We are using res_fax_digium with a Sangoma PRI card on asterisk 1.8.13

The docs at http://docs.digium.com/FAX/fax_for_asterisk_admin_manual.pdf indicate v34  is supported, but when I enable it I get the message "res_fax_digium.c:1624 dgm_fax_new: V.34 not supported, will be ignored."  Is v34 only supported with SpanDSP?

Also, the res_fax.conf.sample does not indicate v34 as a valid modem.
