Asterisk 1.6.1.13 and T.38 faxing
Hello everyone.
I'm struggling to get T.38 faxing to work in Asterisk 1.6.1.13 with a SIP DID provider here in Brazil (GVT - Vox IP service). Here's my scenario:
When faxes arrive by a specific DID, they are routed thru this simple macro:
[macro-recebefax]
exten => s,1,Set(DB(fax/count)=$[${DB(fax/count)} + 1])
exten => s,n,Set(FAXCOUNT=${DB(fax/count)})
exten =>

Having both R-current and R-devel installed on Ubuntu
Hi Dirk,
I too would need to get R-devel on my Ubuntu box (alongside an
existing R installation) to check my packages, especially given the
mayhem that awaits us when the new `R CMD check --as-cran` goes live.
( http://stat.ethz.ch/R-manual/R-devel/doc/html/NEWS.html )
I was wondering if the script that you posted on r-sig-debian a couple
years back was still valid. More however, I'd like to

Send 200 OK with SDP instead of 183 with SDP when ringing starts
Hello, all. I have an asterisk 2.3.2 and a Sangoma interface through
which I connected an external PSTN line. I use it as carrier for VoIP
calls. I can make successfully calls, but there's one problem, I receive
200 OK with SDP with delay (sometimes more than 30 seconds).
So when I make a call through asterisk I receive intially:
- 100 Trying
- 183 Session Progress, with SDP

Asterisk translates 200 OK + SDP into 488 not acceptable here after both side agreed on codec.
Hi List
Asterisk 16.28.0 in use.
PJSIP in use
Two endpoints
Both using IPv6
One Endpoint on UDP, the other via TLS.
Both with:
t38_udptl=yes
;fax_detect=yes
;fax_detect_timeout=30
rtp_ipv6=yes
Both sides are T.38 capable and detect fax tone so no need for fax
detection on asterisk.
Voice calls between the two work fine.
But on a Fax call, I see this situation:

How to defer SDP in ACK for unit testing purposes
Hello,
I think I met a case similar to the one solved by [1] . Quoting this case :
* res_pjsip: Handle deferred SDP hold/unhold properly.
Some SIP devices indicate hold/unhold using deferred SDP reinvites. In
other words, they provide no SDP in the reinvite.
A typical transaction that starts hold might look something like this:
* Device sends reinvite with no SDP
* Asterisk

OPTIONS support for SDP
I have been sending OPTIONS requests 1) programatically (my own code),
2)manually via SIP VERIFY PEER x and 3)automatcially by setting verify=yes
in sip.conf. The trouble is I do not see anything except an ACK 200 come
back from endpoints and it does not contain any SDP/codec info. . My goal is
to determine audio and video codec capability in advance of a call INVITE. I

180 Ringing with SDP
We're dialing a disconnected number via Level 3's vector network, and
are receiving this. The response has SDP in it. Apparently, Level 3 is
playing early media. Asterisk doesn't seem to know what to do with SDP
in a 180 RINGING, and just plays ringing. What am I missing here? How
can Asterisk see there's SDP, early media, in the response and act
accordingly?

SIP/SDP for MulticastRTP page
Hi everyone,
I am sending out a multicast page using the following in my dialplan:
Page(MulticastRTP/linksys/${MULTICAST_IP_ADDR}:6061/${MULTICAST_IP_ADDR}:6061,q)
Everything works great, but I had a question about SIP and SDP:
Should I be seeing a SIP/SDP message from the asterisk server containing media information and the multicast IP address? On wireshark, I see SIP/SDP from the admin

SDP a=ice-ufrag & a=ice-pwd UNSUPPORTED OR FAILED
Hello list
when trying to set up webRTC communications with sipjs client package
(tried 0.7.0, 0.10.0 and 0.19.0), I see in the asterisk debug log-file
the following :
DEBUG[30891][C-00000000] chan_sip.c: Processing media-level (audio) SDP
c=IN IP4 99.88.77.66... OK.

1.4 with a nortel call server 1000 running SIP(sdp headers)
Actually, there was recently a bug fixed regarding multipart SDP parsing in chan_sip. That should have fixed the issue with CS1000s and SIP (among other things). I haven't actually tried it yet on my CS1000, but it should work.
Regards,

Asterisk removes SDP from 180 with SDP
Asterisk receives a 180 Ringing with SDP from the called side, then it sends 180 without SDP to the calling side.
We would like asterisk to sends to the calling side the same response that was received from the called side.
This is Asterisk cert 13.1, is that a new behavior, is there a setting to change this ?
?

no ring back 180 with SDP
I have a box (Genband) expecting the following:
100 trying
180 ringing with SDP
Or
100 trying
183 with SDP
And asterisk is sending:
100 trying
180 ringing
183 with SDP
Any way to modify asterisk to send what he is expecting?
Thanks,
Dave

Asterisk rejects sdp from webrtc client
Hello,
I was testing with sdp and something came up worth asking:
While calling from a webrtc client to another (chrome, sip.js) Asterisk
receives the following sdp and rejects it with 488 Not Acceptable. Why does
this happen, what's wrong with the sdp? The second sdp body below is
accepted instead. Both have rtp profile RTP/SAVPF, difference is that the
second one was produced by rtpengine,

Asterisk behind NAT and Kamailio --> Internal IP in SDP and not "externip"
Hi,
We have some Asterisk servers that we are moving behind a NAT to
preserve public addresses and make room for growth. This is Asterisk 1.4
NAT works very good with the externip/localnet-setting when we are
connected directly to our teleco. But when I try to use NAT and put them
behind our Kamailio something interesting happens: The media-address in
the SDP is the internal ip and not the
