Summary:                    Asterisk says "No compatible codecs, not accepting
this offer!" on T.38 offer
Description: 
Hi community,

first of all: this is the first bug report in my life.

Since I updated asterisk from 1.4.25 to 1.4.28 I get the the following
message when I try to send or receive a fax with T.38 through asterisk:

"NOTICE[11689]: chan_sip.c:5621 process_sdp: No compatible codecs, not
accepting this offer!"

This is my setup for receiving faxes:
Provider with T.38 support ---SIP---> Asterisk with T.38 pass through
---SIP---> Callweaver with T.38 support

This is my setup for sending faxes:
Linksys SPA 2102 with T.38 support ---SIP---> Asterisk with T.38 pass
through ---SIP---> Provider with T.38 support


With asterisk version 1.4.25 I never saw this message.

Seems like this issue already existed in the past. See
https://issues.asterisk.org/view.php?id=12414

Please let me know if there is any further information needed.

Rgs,
schogge
