OK, not sure I understand, but I think I resolved some issues: * The 1005 client had the STUN server settings enabled. But this is entirely within my network, without any NAT. So this setting not appropriate. Had I known better, I would have realised that the Contact field shown in the registrations was showing my external IP address, not the internal IP address which is required. The USER_NOT_REGISTERED message is a red hearing, I still get that when it is working. Weird. * Perhaps, just to make things more confusing the above only applies to IPv4, my IPv6 address was correct. Although my logs show that the 1005 was being registered to the IPv6 profile using its IPv4 address. Huh? Something to do with the client I guess (zoiper). This explains why calls worked one way, but not the other way. * For some reason setting zrtp_secure_media=false kills incoming connection handling. As in answering calls fails. Despite the fact all clients appear to have ZRTP disabled. Huh? I don't understand... * Now that I have worked out these unrelated issues, to investigate the 10 second audio problem again.

Just quick summary of the some of the other issues:
* Occasionally the calls just freeze. Nothing shown in freeswitch logs. No sign of any packets being dropped. Just client (zoiper) freezes and does nothing. I suspect this might be a client issue, maybe nothing to do with freeswitch.
* (the real problem I am trying to investigate) outgoing PSTN calls work fine. But incoming calls from our VOIP provider - there is a 10+ second delay on all incoming audio, and I can't see any reason for this. i.e. I mean I say something on remote end, wait 10 seconds, then it is received at local end.
* Turning on echo cancellation on a Linux based host running zoiper seemed to cut out audio after about 1 second. So I disabled that option, seems to have fixed that problem.
