Re: [SR-Users] OPTION pings with dispatcher to asterisk box

Hi Karsten, have a look to the docs: “e.g. "class=2" would accept everything from 200 to 299 as valid response” – so that class 4 is probably everything from 400 – 499.

But i am confused about the dispatcher documentation. What means the class=4 in the attributes field? AFAIK from now, dispatcher OPTION pings cans be only configured global with modparam settings, same as you can only global enable or disable OPTION pinging. Maybe some developers knows that example with "class=4" is meaning here. https://kamailio.org/docs/modules/5.3.x/modules/dispatcher.html#dispatcher.… For database, each element of a line resides in a different column. Next is a dispatcher.list file example: Example 1.50. dispatcher list file ... # # dispatcher destination sets (groups) # # line format # setid(int) destination(sip uri) flags(int,opt) priority(int,opt) attributes(str,opt) # proxies 2 sip:127.0.0.1:5080;transport=tcp 0 10 class=4;prefix=448;strip=2 Cheers Karsten Am Sa., 14.

And in dispatcher I wrote the seperator correctly. Will check that monday. Cheers Karsten Joel Serrano <joel@textplus.com<mailto:joel@textplus.com>> schrieb am Sa., 14. Dez. 2019, 03:26: Hey Karsten, I'm using that same modparam and it's working as expected. My example: modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=403;code=488;code=405;class=3") I believe the problem is that you are using a comma "," as separator, and the correct separator is a semi-colon ";"??? BTW (offtopic), to make Asterisk answer with a 200 OK, you can do the following: Add to extensions.conf... [default] exten => s,1,Wait(1) same => n,Hangup This will make asterisk respond with a 200OK instead of a 404 Not Found. This "default" is dependent on the context= parameter in sip.conf, if you have changed it, you will have to name the extension accordingly. And lastly, AFAIR you don't need the wait(1) and probably can do the hangup() directly, I needed it for different reasons, give it a try. This works for OPTIONS sent to a sip:IP:Port address, if you are using a monitoring system or cli tool or similar that sends OPTIONS to sip:something@ip:port, then the following dialplan works (I'll use "nagios" as an example: sip:nagios@X.X.X.X:5060) : [default] exten => nagios,1,Wait(1) same => n,Hangup You can combine both if you have both kinds: [default] exten => s,1,Wait(1) same => n,Hangup exten => nagios,1,Wait(1) same => n,Hangup etc.... Hope this helps! Joel.

Now i have someone with asterisk that answers with 401 or 404 (depends on asterisk version). So i tried code=401;code=404 as aditional attrs. Seems not to work. Also i tired to change the modparam from class=2 to this: modparam("dispatcher", "ds_ping_reply_codes", "class=2,code=401,code=404") Is that a "bug" or a hidden feature, or i missed something?
