Re: [Serusers] dropping call after ~15 sec "I won't send a reply for ACK!!" - sr-users

Hi,

Adding record_route(); to my routing block solved this problem, calls 
work great now! thank you for the pointer :)

  Howdy,

 I had this problem as well.  I believe it was due to the fact
 that I didn't to record routing, and the ACK didn't get back.
 My calls lasted exactly 9 seconds.

 Anyway, it is really handy to do call tracing to debug
 these sorts of things.  If you have a unix machine, tcpdump -w,
 or a windows machine can use ethereal.  You save the sniffer
 session and then process it with 'sipscenario'.  It makes a very
 easy to look at call flow, which will probably highlight the
 problem.

 Of course to do sniffing you have to have a machine that sees all
 of the packets.

 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!
