I'm using SER to shuttle calls between softswitches. I have "softswitch
A" sending calls to the SER proxy, which then does an enum lookup to
make a routing decision and then passes the call on to the appropriate
softswitch. I have been having some strange problems with the setup and
some questions about my config. I sometimes get:
Nov 10 21:14:01 cpser ser[22087]: 483 Too many Hops
Nov 10 21:14:01 cpser ser[22087]: Warning: sl_send_reply: I won't send a
reply for ACK!!
This mostly happens after I do a serctl restart to reload my config. I
assume that is because ACKs are coming in that the stateful transaction
processor doesn't know where to forward them to since I restarted?
There's no other way to reload a config other than a full restart,
correct?
Also I see a lot of "408 Request Timeout" from far end gateways. Is
there something wrong with my config?
Here is my config:
modparam("acc","radius_flag",1)
modparam("acc","failed_transactions",0)
modparam("tm", "fr_inv_timer", 5 )
route{
if ( !mf_process_maxfwd_header("10") )
{
xlog("L_ERR","483 Too many Hops");
sl_send_reply("483","Too Many Hops");
drop();
};
if (msg:len >= 2048 ) {
xlog("L_ERR","513 Message too Big");
sl_send_reply("513", "Message too big");
break;
};
setflag(1);
if (loose_route())
{
t_relay();
break;
};
if (method =="BYE")
{
if ( !t_relay())
{
sl_reply_error();
}
break;
};
if (method =="CANCEL")
{
if ( !t_relay())
{
sl_reply_error();
}
break;
};
if (method =="ACK")
{
if ( !t_relay())
{
sl_reply_error();
}
break;
};
if (method =="INVITE")
{
record_route();
if (uri=~"^sip:[2-9]+@*")
{

if ( !enum_query("e164.internal.net"))
{
strip(1);
prefix("1");
rewritehost("192.168.10.5");
xlog("L_ERR","NANPA number to %tu from
%fu carrier %ru\n");
t_on_failure("1");
t_relay();
break;
}
xlog("L_ERR","NANPA-ENUM number to %tu from %fu

t_relay();
};
# end if block method = invite
}
