Re: [Serusers] rewrite & ACK forwarding problem
by lgfausak＠august.net 30 Apr '04

30 Apr '04

I have also had problems with getting the ACK back. I don't completely understand your configuration, you must allow for packets going both directions, right? Here is my config : route { # check to see if the message has been around too long # probably means that it is looping # if (!mf_process_maxfwd_header("10")) { log("LOG: Too many hops\n"); sl_send_reply("483","Too Many Hops"); break; }; # # make sure the length of the message isn't too long! # if (len_gt( max_len )) { sl_send_reply("513", "Wow -- Message too large"); break; }; # # do the loose-routing thing, this is important! # if(loose_route()) { log(1,"doing top loose route"); t_relay(); break; }; # this is where I was dropping the ACKS. # I was simply dropping these, but they must be relayed # because they can be ACKs if(!(uri==myself)) { if(!t_relay()) { sl_reply_error(); break; }; break; }; This gets the ACKs through for me. By the way, I have this configured with Cisco ATAs, version 2.16. ---greg > >I have the same problem and posed it to the group yesterday ([Serusers] >Ignored 200 OK message.)

[Serusers] Radius accounting - radius_log_flag?
by Steven R. Bunin 16 Jan '04

16 Jan '04

Hi, I have radius authentication working thanks to Jan's help but I am still not receiving any accounting messages to my radius server. I found a mention of setting radius_log_flag but ser 0.9.11 tells me it isn't found in the "acc" module. How can I set invite and goodbye messages (or any others for that matter) to send information to my radius server for accounting purposes. I have read at leat 90% of the old messages but have yet to find an answer. Thanks in advance, Steve

[Serusers] Xten and SER problem
by Jesus Rodriguez 17 Nov '03

17 Nov '03

Hello, I'm trying to register an Xten (1016 build) to SER and i always get a "401" response. Registering an ATA186 to the same SER with the same user and pass works with no problem (logs below Xten). We have tried SIPPS and registers ok too. Xten send the REGISTER, SER answers with a WWW-Authenticate challenge but Xten doesn't send anything, just sends a new REGISTER after few seconds: (c)2003 Xten Networks Inc. All rights reserved.

Steven, I remember having the same problem. In my case, the problem seemed to be in the loose_route processing. I don't know what it has to do with the accounting module, but commenting out this part made the trick in my case. Jaime "Steven R.

Below is the area I believe has the most affect on Radius Acccounting from my Log File. Any suggestions would be appreciated and if it would help to see the full Config file I will send it as well. record_route(); if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!radius_www_authorize("")) { www_challenge("", "0"); break; }; save("location"); break; }; if (method =="INVITE") { log(1,"INVITE\n"); setflag(1); }; if (method=="MESSAGE") { log(1,"MESSAGE\n"); setflag(1); }; if (method=="BYE"){ log (1, "BYE or CANCEL\n"); setflag(1); }; if (method=="CANCEL"){ log (1, "BYE or CANCEL\n"); setflag(1); }; Thanks in advance, Steve _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers ******************************************************************************* Important.

RE: [Serusers] Implementing Voicemail

>> I did place this portion inside the myself check >>and it still tries to transfer to vm after the time expires. >I'm puzzled -- did not you want to transfer to vm after the time expires? I will try to make this clearer. I am behind an ATA with a SIP proxy of 209.242.10.153. If I call someone else registered on my domain and they are not available, I want to go to voice mail. If I call 1-800-555-1212 from my phone, I do not want my sip proxy to reroute the call to voicemail after 10 seconds if no one answers(or ever for that matter). Right now if I dial 18005551212 from my handset, I see the destination as sip:18005551212@209.242.10.153 on the server which matches to myself and ser tries to send it to voicemail. Someone calling into the network is not a problem. They will never hit our server unless the destination is local. >>This is the part that I really need help with!
