I saw an issue similar to what you describe when a snom300 could not resolve its NTP server address. I cannot explain it, but sorting out DNS sorted out the communication issue.

Re: [asterisk-users] sporadic one-way audio
Hi For the sporadic one way audio, check that the codec list in the snom phones is the same as set by the server. The codec list is in the RTP tab of the identities.

Re: [asterisk-users] Sporadic One Way Audio
I don't think it's a snom specific issue as I have 5 branch offices all with identical configurations and only one of the 5 is experiencing this problem. I have checked and re-checked the config files until they're practically burned into my brain and everything appears looks OK. Any place there is a config option for the server address it matches the server's physical address. The phones and all computers on the network are statically assigned (these are very small 1-person or 2 at the most offices) so I'm absolutely sure that there is no chance of an IP conflict. The phones and the Asterisk server are plugged in to the same ethernet switch. I have tried tried using both sip debug and Wireshark to try to catch anything relating to this, but the calls seem to happen very rarely and, as usually happens when I'm trying to troubleshoot some sporadic problem, the two people in that office can't ever reliably reproduce this when I happen to be in the office or remotely logged in to the server. To make things even more difficult, the Snom phones have a switch built in to them and the PC's are in the pass-through port. This means that any traffic generated by the phones is in the PC's blind spot. Anyway, I've got about 1000 other projects going right now. Once I get a couple of the more pressing ones knocked out I'll try to spend a couple of days at the problematic office and see if I can't come up with some way to resolve the problem.

Re: [asterisk-users] Sporadic One Way Audio
We have seen cases where an IP address conflict caused something like this. You can take Wireshark traces on the PC (possibly run them in a loop so that you have a pretty long context) and if you have one-way audio be quick to log on to the web interface of the phone and also take a wireshark (PCAP) trace. There are a couple of tools available that may help to track such problems down: http://manageengine.adventnet.com/products/vqmanager, http://palladion.net, www.networkinstruments.de, and www.voipfuture.com. I know some of them offer a 14-days demo, and it tremendeously helped on of our clients to fix network problems. You can also use SNMP tools to poll if the phone has any blackouts regaring network availbility (see http://wiki.snom.com/SNMP). Also the phone sends a statistics at the end of each call. Check the BYE message, there is a counter of received and transmitted packets. Those numbers should be roughtly the same.

The asterisk server is connected to the PSTN via a Rhino R4FXO-EC card. The lost RTP would have be between the Asterisk server and the phones.
