Hi, I'm setting up a vega 50 BRI with ser, and I can make in/out bound calls, quality is great! I have a problem, when I dial from a sip phone to a land line, my call gets set up, and works great, but after approx 15 seconds it drops the call. Below is what I get in the logs from ser. 0(29026) DEBUG: is_maxfwd_present: max_forwards header not found! 0(29026) DEBUG: add_param: tag=4063815580 0(29026) end of header reached, state=29 0(29026) parse_headers: flags=256 0(29026) find_first_route(): No Route headers found 0(29026) loose_route(): There is no Route HF 0(29026) check_self - checking if host==us: 9==9 && [10.0.0.11] == [10.0.0.11] 0(29026) lookup(): '0868594416' Not found in usrloc 0(29026) Warning: sl_send_reply: I won't send a reply for ACK!! 0(29026) receive_msg: cleaning up My Version of ser is: # ser -V version: ser 0.8.11 (i386/freebsd) flags: STATS:Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.162.2.5 2003/08/27 16:04:35 andrei Exp $ main.c compiled on 11:29:10 Sep 5 2003 with gcc 2.95 Does anyone know hwta may be going wrong here?
