Thank you!Now a customer with and FreePBX 2.9.0 (Asterisk 1.8.20.1) ran into the same issue with our SBC. I told him to set rtpkeepalive=1 in sip.conf but I don't see this version sending any comfort noise packets. Isn't there any way to disable this nat detection feature completely in asterisk? (nat=no does not seem to do the trick) Mit freundlichen Grüssen -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

(nat=no does not seem to do the trick)I don't remember 1.8 or the various options, you'd need to verify with the sample configuration file. Strict RTP protection can be disabled in rtp.conf using the strictrtp option. Otherwise it's not something in Asterisk that stops this kind of stuff, it's the NAT Implementation in the router. -- Joshua Colp Digium, Inc. | Senior Software Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - US Check us out at: www.digium.com & www.asterisk.org
