The nat=yes option assumes that it is okay to send RTP back to the source port from which it originated, irrespectively of what's in the SDP.

Re: [asterisk-users] Nat=yes
Hi, I am unsure of what you are saying. Just for discussion, if one has a control on the insertion of the IP address in the SIP header, then nat options working can be verified & observed. In the OSI reference model, the "Network" is layer 3, IP. Call it Network, layer 3, or IP, it is the same. All-right, by IP from the network layer I meant, the IP address in the IP Header/Network layer/layer 3. & IP from SIP I meant, SIP request generator's IP address in the SIP Header. I missed the word address. My customers don't really care for things that don't work. May be its useful for SIP application developers rather then end customers. Have a good time.

Re: [asterisk-users] nat=yes
If you set yes then asterisk assumes that the address its coming from is not the same as the UA thinks it is. most devices will not operate properly if set to yes when they are in fact local.

Re: [Asterisk-Users] nat=yes in sip.con (changed subject)
Hmm. this rings a bell, try putting nat=yes in your sip.conf, I think that fixed the problem for me. (Or was the the login timed out thing? *shrug*) The manual is not very clear on what happens with nat=yes in sip.conf. Anyone here that could write a simple explanation of this option? /O ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
