Hello, I have a strange problem whenever I have 2 or more BT100s behind NAT. I am not able to reproduce this error reliably, but it happens every 2-5 minutes.
The general setup is that there is Asterisk server sitting at a central location. Some peers connect directly (206,205,201) but some (204,203,200) connect through NAT. This all works fine ...but it is extremely unreliable ... I get UNREACHABLE and then OK again ... UNREACHABLE and OK again .. unpredictably. When it's OK I can make phone calls no problem.... of course when it goes UNREACHABLE there is trouble. I tried to replace one of the BT100 phones with X-Lite and that one is OK (~40ms) rock solid - or seems to be so far. So it seems that there is something weird going on with BT100 My configuration of BT100 is as follows: - firmware 1.0.5.23 (I've noticed similar problems with .16 also) - detected NAT type is symmetric NAT - STUN stun.xten.net (I'm using Xtens ... or do I have to use my own???) - no outbound proxy - register expiration = 1 - keep alive interval = 20 sec (I also tried as low as 1 sec) My sip configuration uses: - nat = yes - qualify = yes (I also tried longer qualify 10000 with no luck) This is what I get with sip show peers ... the 204 and 200 are BT100 and sometimes one or both go UNREACHABLE for a while ... 203 is X-Lite and didn't go UNREACHABLE yet. 206/206 (Unspecified) D 255.255.255.255 0 Unmonitored 205/205 (Unspecified) D 255.255.255.255 0 Unmonitored 204/204 209.x.x.125 D N 255.255.255.255 38340 OK (40 ms) 203/203 209.x.x.125 D N 255.255.255.255 1548 OK (38 ms) 201/201 192.168.2.112 D 255.255.255.255 5060 Unmonitored 200/200 209.x.x.125 D N 255.255.255.255 37838 UNREACHABLE Any ideas? Is there some trick to get BT100 to cooperate?
