Thanks MC. Had to load the pcapdev-lib, but got pcapsipdump installed.*** *

My wife had just called my cell and got one way audio. So I ran: pcapsipdump -f -p -i eth0 -d /tmp -n <my number>****
Of course I got 2 way audio. I called the one that ALWAYS fails …. Got 2 way audio! Does pcapsipdump fix it? lol****

I will try in day time tomorrow and see if we can get a failure.****

Nothing in the freeswitch.log of value? I didn’t see anything, but there is still a lot for me to learn there.****

Sean,****
Glad to hear you're making progress with using tcpdump and other packet capture-ish tools. You've successfully captured the SIP call leg between your phone and your FreeSWITCH. That's good, but it's incomplete. You really want SIP and RTP both, and you want the call leg between FreeSWITCH and the telco. You have a few options:****
Expand your tcpdump. In other words, cast a wider net. Pro: easy to do. Con: creates massive pcap files through which you must sift to find the call in question.****
Use pcapsipdump. Pro: does all the work for you by putting SIP and RTP for each call leg into a single file. Cons: You have to compile it yourself, and it creates a whole lot of files, so you'll need to get used to it.****
My personal opinion is this: if you never, ever have to debug a SIP call ever again then just use tcpdump. However, if you're the phone guy and you'll be doing this again in the future then bite the bullet and learn pcapsipdump. Believe me it's worth it.****

Hi all,****
****
First, I am on version: FreeSWITCH Version 1.2.5.3+git~20121219T035317Z~2b4aa48049 (git 2b4aa48 2012-12-19 03:53:17Z) I hope to move to the Stable 1.2.9 this weekend.****
****
I am having very reliable one way audio when calling Sprint Cell Phone users, though not every time. I got this reproducible on my phone, but by the time I learned tcpdump command, it was working again. However, the user that reported it seems to get it almost everytime.****
****
Helpful tidbits:****
· I THINK it happens in either direction.****
· For this person at his home, it appears to be every time (for now)****
· He reports calling (to or from) other Sprint Cell users results in the same problem from our FS****
· It appears to only be true with Sprint Cell calls! (But my users say that’s not Sprints fault!)****
****
Scenario:****
I place a call from my Desk Cisco Phone (220) to his number 410493nnnn and it rings, he answers, I can hear him crystal clear … he can’t hear me at all. I had a theory that it worked after 30 seconds (on my cell), but that does not hold true on his cell.****
****
Here is the FS logfile: http://www.bizfocused.com/Sean/fs_problem/freeswitch_no_audio_in.log.txt** **
And here is the tcpdump output: http://www.bizfocused.com/Sean/fs_problem/dump.pcap.zip ****
****
Based on the small size of the file, I suspect someone is going to say “do it again with this tcpdump command”. I welcome the education.****
****
Anyway, any insight will be appreciated.****
