[Asterisk-Users] Asterisk Fax Question

[mkumar at mantragroup.com]

Hi All,

I want to configure fax with Asterisk and I found that we can do this reliably
using G711 codec only. Currently my provider is supporting G729 and G711.
During the call initiation the call starts with G729 (1'st priority) and
somehow if the receiver is unable to receive call then we are providing the
Caller to send a fax, but at that point they are using G729 codec. At this
point how can the user send the fax using G711? We want to use G711 only as Fax
is delivered reliably using it. Please tell me whether this is possible and if
possible how can we achieve it after the call is accepted with G729?

Thanks for your help and time,
Manoj.
