After some testing I found following: 1. When I try to bridge call between endpoints, there are always no RTPs from FreeSWITCH (like I wrote before). 2. When I just answer call on FS and play something localy (i.e. music) everything works fine - FS sends RTPs like expected. All tested with various endpoints (Linksys, Snom, Nokia, Asterisk :-) and from public IPs, private IPs at foreign LAN, private IPs at the same LAN as FreeSWITCH is (yes, I have separate profile for phones in the same LAN). And I found no difference. Any hint is really appreciated :-) Best regards, kokoska.rokoska kokoska rokoska napsal(a):
Thank you very much, Brian, for your help!
I have just upgraded to curent trunk, but all remains the same - RTPs from both endpoints arrives to the FreeSWITCH but no RTPs are send back from FS (using ngrep I can't see even single RTP packet comming from FS).
I think it is due to my misconfiguration, but I have no idea where.
I have trid to blindly modify followed params to (I hope) all possible values combination (including manual ones :-), but with no luck:
<param name='apply-nat-acl' value='rfc1918.auto'/> <param name='local-network-acl' value='localnet.auto'/> <param name='disable-rtp-auto-adjust' value='false'/> <param name='rtp-autofix-timing' value='false'/>

Ok update in a few I now recall why we had that && ! sofia_test_pflag(tech_pvt->profile, PFLAG_AUTO_NAT) in there.

Now are all IPs correct :-) (BTW: In my previous post I mean "c" line in SDP, not "m" line). Thanks once more!
Well, signaling works fine, but I still have troubles with RTPs: I can see with ngrep RTPs going to FreeSWITCH from both legs (a, b) but there are not outgoing RTPs from FreeSWITCH to any of the call legs. And, of course, caller and callee hear nothing :-)
Could you, please, help me to solve this? Thanks.

You have to set the local-network-acl on the profile so it knows when or not to fix up the VIA /b

Hi all,
I have just upgarded my (a little bit old :-) FreeSWITCH to current trunk and now i have troubles with IP addresses in SIP & SDP, while before upgrade everything work fine...
My FreeSWITCH is behind NAT and all relevant sip profiles have set:
<param name="ext-rtp-ip" value="1.2.3.4"/> <param name="ext-sip-ip" value="1.2.3.4"/>
But when I send INVITE thru the profile to the gateway associated with it i see local IP in "Via" header and in SDP "m" line too. BTW: The "Contact" header is populated with "external" IP (1.2.3.4)
