Daniel Steglich commented on ASTERISK-24210:
--------------------------------------------
update:
seems like first "Connection Information" is related to session description and second one to media description - so asterisk seems to behave correct.

> Key: ASTERISK-24210
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-24210
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Resources/res_fax
> Affects Versions: 11.11.0
> Environment: Linux vargas 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux
> compiled asterisk from here:
> http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz
> Reporter: Daniel Steglich
> Assignee: Matt Jordan
> Attachments: asterisk-cli-debug.txt, asterisk-fax-env.txt, extensions.conf, sip.conf
>
>
> I configured a Fax2Mail extension (details see extensions.conf)
> Now I delete the following lines from sip.conf (see attached)
> nat=comedia
> t38pt_usertpsource=yes
> Then send a Fax from my peer 550000 to 429 (with T.38 enabled).
> Asterisk is sending re-invite and switching to T.38 which works fine.
> But the "connection information" from the "200 OK with SDP" from the client will be ignored.
> This means, when I start network trace on ethernet Interface connected to my peer, I do not see any udptl frames. When I start network trace on "lo" Interface of debian Server, I can see the udptl Frames (destination IP = IP where asterisk is bound to i.e. IP adress of eth1) which are rejected with icmp port unreachable.
> when adding the lines from above:
> nat=comedia
> t38pt_usertpsource=yes
> udptl is sent correctly.
