Hi,
Anyone has experienced an one way audio problem after a call is made?
Here is my case.
openser1.0.1 + mediarproxy 1.4.2
User behind NAT can make a call without problem.
When user with no NAT (direct connect to the internet), one way audio
will happen. Anyone can suggest a way to trace the problem.
Thanks,
unplug

sniff the network and see if the SDP is SIP messages are right, maybe
you misconfigured the proxy and try to do (improper) media relaying for
not natted users.

I am troubleshooting the one way audio problem for almost a week but I
still find nothing to solve it.
I am using mediaproxy as a NAT proxy. I have tried a IP phone with
NAT and one without NAT. Below are the combination and the result.
call making from one party to another party
party A party B
1) IP phone (NAT) <--> PSTN : no problem
2) IP phone (NAT) <--> IP phone (no NAT) : no problem
3) PSTN --> IP phone (no NAT) : no problem
4) IP phone (No NAT) --> PSTN : one way audio problem
In case 4, party A speaks but party B hears nothing (no noise & only
slient). Party B speaks and party A can hear.
First of all, anyone can tell me whether it is the correct information
store in location for a non-NAT user.
first row is a NAT user and the second row is a non NAT user (received field
is null)
| username | domain | contact |
received | expires | q | callid
| cseq | last_modified | flags | user_agent
| socket |
| 871966629896 | | sip:871966629896@10.0.0.78:5060 |
sip:210.184.23.31:5060 | 2006-04-26 17:28:43 | -1.00 |
ZpFfQWHzpzbJpyLU(a)10.0.0.78 | 2501 | 2006-04-26 17:28:09 | 1
| KE10XX v4.32.10 00-09-45-0a-fc-7b | 203.193.26.234_5060 |
| 871966760539 | | sip:871966760539@218.189.176.170:5060 | NULL

| KE10XX v4.32.14 00-09-45-0a-fc-29 | 203.193.26.234_5060 |
Then, I have compared the log from ngrep but can't find anything
special to cause the problem.
Below is the log from ngrep for the case 4 that cause one way audio problem.
I have compared with other cases above in the section of SDP but nothing found.
http://fisher.no-ip.com/ngrep/nonat2pstn1.log
Below is the configuration of our system.
IP phone (NAT) --- openser --- CISCO --- PSTN --- phone
IP phone (no NAT)-----+
As the result shown above and only case 4 has problem. Will the one
way audio caused by CISCO?
Anyone can help?

You hvae to use a paket sniffer to verify the RTP
stream. Check if IP
Phone (no NAT) send RTP packets to Cisco.
Check if RTP packets from IP Phone arrive at Cisco.
Check logs at Cisco to see if RTP packets are rejected or cause any
problems.
Check Cisco access rules - maybe you block all traffic except from the
SIP proxy (= RTP proxy). (Try disable all IP access rules and check if
it works)
