<div><br></div><div>In this scenario it happend to me - that the T38 Offer (with corrent m=image and port in sdp) got forwarded by freeswitch to asterisk, asterisk did forwarded without the T38 Offer (don't know why) - so also without the m=image sdp part - the ATA did answered correctly (without m=image part) -> asterisk did created a new sdp with m=image 0, without T38 parts - and returned this to freeswitch.</div>
<div><br></div><div>Freeswitch did hangup the call - because sofia_glue did extracted the port 0 as audio port - and this is not a legal port...</div><div><br></div><div>Sending port 0 is according to rfc legal - so freeswitch should ignore it in this case.</div>
<div><br></div><div>the question is - if both values are given - which one is the value we need ? I think the audio port is the port which is of higher priority.</div><div><br></div><div>So the workflow should be:</div><div>
- Try to extract audio port from m=audio part.</div><div> - If you got it - and it is a valid port then go on</div><div> - else try to extract audio port from m=image part...</div><div><br></div><div>The function in question is sofia_glue_tech_proxy_remote_addr - in sofia_glue.c</div>
<div><br></div><div>Is it generaly a good idea to use the m=image part as audio port ? Why is there no direct image port member in the pvt structure as with the video port ?</div><div><br></div><div>Hope someone can help here...</div>

colleague Brian West took some much-deserved time off last week so the
rest of us were a bit busier than usual. Brian does an amazing amount of
work on FreeSWITCH, CudaTel, and ClueCon, so we're definitely glad he's
back to work!<br>
<br>On last week's <a href="http://wiki.freeswitch.org/wiki/FS_weekly_2013_03_20" target="_blank">conference call</a>
we talked about Debian packaging with a little VoIP security and ZRTP
thrown in for good measure. Interestingly, a number of people stayed on
the call until 6pm EST! You are welcome to stay in the public conference
room for as long as you like. This <a href="http://wiki.freeswitch.org/wiki/FS_weekly_2013_03_27" target="_blank">week</a>
we have Mark Crane scheduled to give us an update on FusionPBX. It's
been about 12 months since we last heard from him. We are looking
forward to seeing the improvements that have been added in the past
year.<br>
<br>We are also gearing up for <a href="http://www.cluecon.com" target="_blank">ClueCon 2013</a>
so save the date: August 6-8, 2013. If you have any questions about
being a speaker, sponsor, or attendee then by all means contact us at
this email address. Remember that WebRTC is a big topic in the news
right now and we are looking for folks to talk about WebRTC in their
open source telephony projects and solutions. <br>
<br>Have a great week and we'll talk to you again in April!<br clear="all"><br>-- <br>Michael S Collins<div>ClueCon Team<br><div><a href="http://www.cluecon.com" target="_blank">http://www.cluecon.com</a></div><div>877-7-4ACLUE</div>
