Hi, I'm using qualify= on my asterisk server that provides outgoing pstn calls to a few companies.
I've got one client in particular that has their own asterisk server which is connected to my server. This client seems to be having a nat issue. It's not a connectivity issue as i've tried constant pings and the line is up constantly. I'm getting the following: [2010-11-13 17:56:27] NOTICE[26082] chan_sip.c: Peer 'client_201' is now UNREACHABLE! Last qualify: 29 [2010-11-13 17:56:37] NOTICE[26082] chan_sip.c: Peer 'client _201' is now Reachable. (26ms / 5000ms) [2010-11-13 17:58:12] NOTICE[26082] chan_sip.c: Peer 'client _201' is now UNREACHABLE! Last qualify: 28 [2010-11-13 17:58:22] NOTICE[26082] chan_sip.c: Peer 'client _201' is now Reachable.

Last qualify: 27 [2010-11-13 18:00:08] NOTICE[26082] chan_sip.c: Peer 'client _201' is now Reachable. (27ms / 5000ms) [2010-11-13 18:01:43] NOTICE[26082] chan_sip.c: Peer 'client _201' is now UNREACHABLE!

(28ms / 5000ms) Looking at the sip log, on the client's server, the sip OPTIONS packets arent being received. Then suddenly the sip packets start being received again. (without sending out a new packet to open up the nat mapping). I've tried replacing the router because I thought it was faulty. Here is the SIP log from my server: http://pastebin.com/ZbDYGG9R Finally, I tried mapping port 5060 so to avoid NAT issues, but that didnt help. Could there be an ISP problem? Any assistance would be appreciated. Many thanks Dan
