New subject: [Serusers] Server Error

27 Nov 2003

Well, I activated the max forward check and also added the 'alias=
192.168.1.240' to the global config section of the ser.cfg. But I am still
getting "483 too many hops" I have disabled register for the time being. But
then i should be getting 404 and not 483 as you suggested.If its a problem of
local memory being overrun, how do i resolve this issue? 
Have attached the ser.cfg file for ref. Any comments? 
Regards and TIA,
Urvish

Simply Ser does not recognize, that 192.168.1.240 is its local name (probably 
because that IP is not resolvable via DNS). And, for whatever reason, you 
deactivated the maximum forward check. Thus the INVITE is forward in an 
endless loop to Ser itself (you can probably see that if you sniff on the 
loopback interface). Finaly the request is probably getting so big, that Ser 
is getting out of (local) memory.
1. activate the maximxum forward check in the begining of your route section. 
Then you should receive "483 Too Many Hops" instead of the 500.
2. add 'alias = 192.168.1.240' to your global config section, then Ser should 
recognize that the request is for the local proxy (and you will probably 
receive 404, because your phone is not regeistered)

  i have  a 6 line SIP phone. Its IP address is
192.168.1.159. Im placing a
 call to 5555 ( another line on the same phone). I have set the proxy for
 both the lines to my SERs IP address (192.168.1.240).I havent enabled
 register with proxy on the phone but i tried that before and that gave me
 the same server error as the one mentioned below.

 These are the packets that i have captured while making the call. Now the
 problem is that I am unable to understand the kind of internal
 error it is giving.

 Also the SIP message header of Packet 20 , as shown below, talks about
 warning 392. Does anyone know what warning it is?
