[Serusers] SIP MESSAGE method revisited.
by sip 17 Aug '06

17 Aug '06

Okay, Since I've been unable to pass SIP MESSAGEs back and forth through our server, but knowing full well that I once was able, I decided to take our configuration and remove everything in it that we've added over time (slowly regressing back to the beginning of our SVN code repository for the SER config) and see if I could tell what had changed so that I can no longer pass a SIP MESSAGE back and forth between clients. It didn't work. SO... I decided to take the hello-world config and try with it. No luck. What am I missing here? Is there some special handling that is needed to pass a SIP MESSAGE in SER 0.9.6? Is there a chance that something basic would have changed between 0.9.0 (our original server) and 0.9.6 that would have broken our ability to pass the MESSAGE method without additional tinkering? Sure, if I put in a block like: if(method=="MESSAGE") { sl_send_reply("200", "OK"); }; ... it's clear the message gets there and I receive the 200 OK, but of course it doesn't go anywhere after that. Without that block in there, it ends up getting a 513 Message too big response (which seems to be somewhat of a default for messages that don't end up getting handled in any other way that SER understands). I'm now completely at a loss. Pointers. Tips. Snide remarks. Anything helpful would be greatly appreciated. N.

[Users] Problem with a NATing proxy
by Jeremie Le Hen 17 Aug '06

17 Aug '06

Hi, first of all, I am new to the SIP world, so please forgive me if I ask anything dumb. I am trying to set up a NAT-traversal SIP proxy, with the help of the nathelper module and rtpproxy. I only have access to the proxy and one softphone behind it. I am facing two problems: when someone in the outer world wants to call my softphone (which is behind the proxy), the proxy forwards the INVITE message to itself and recurses until the mf_process_maxfwd_header() statement stops further processing. I am not sure how to handle this. My guess is that I should use the registrar module and when the proxy receives an INVITE message, it should use registered() method in order to know where to forward the request ; but I don't know how to do that. Help would be welcome. My second problem is that when the peer hangs off the phone, I should receive a BYE message but I can't see it. Given I have no access on the other end, I guessed that the BYE message had been sent elsewhere. That's why I fixed the Contact header field. However, I still can't see actions coming from the outer phone. Any idea ? (I didn't attached any packet dump for now because I think it can be more misleading than informative because there are two proxies on the same machine: one that is a tunnel broker to encapsulate VoIP traffic in HTTP, and the other one is OpenSER. Basically, every SIP session is being tunneled in HTTP, then the datagram in unwrapped by the first proxy and then forwarded to the second one, which is OpenSER. Nonetheless I would be glad to provide any packet dump upon request.) My configuration file is attached. If you find any other mistakes or inconsistencies in this configuration file, please tell me.

[Serusers] Ser with Asterisk for Voicemail
by Ricardo Carvalho 17 Aug '06

17 Aug '06

Hi, I'm deploying a SER + Asterisk architecture, where SER is used to manage acc, users database and sip routing, and Asterisk is used for voicemail and PSTN gateway. How should I edit ser.cfg to make Ser redirect calls to Asterisk when the user doesn't answer his phone or when the user exists but it hasn't any phone registered? If I'm using also Asterisk for Gateway purpose, I guess all calls to be sent to PSTN, Ser redirects them to Asterisk, but it will try to find a mailbox for every number dialled, when it should distinguish calls for PSTN not to be sent to Voicemail. How can Asterisk distinguish between a call sent for voicemail and a call sent by ser to be redirected to PSTN? It depends on the configuration made in ser.cfg? Thanks, Ricardo.

[Users] ACK Routing: Best practices?
by Carsten Bock 17 Aug '06

17 Aug '06

Hi everybody, Short question: Are there any best practices regarding the routing of ACK Messages? Currently we have the following logic implemented: route { [...] ################################################################################################################## # Check for Re-Transmissions (not ACK/CANCEL) ############################################################################################################### if ((method != "CANCEL") && (method != "ACK")) { if (t_check_trans()) { log(1, "Re-Transmission detected, message dropped.\n"); # Drop the message silently. return; } } ################################################################################################################## # Loose-Routing (RFC3261) ############################################################################################################### if (loose_route()) { route(10); return; }; # if (loose_route()) { ################################################################################################################## # ACK/CANCEL Messages may be relayed ############################################################################################################### if ((method == "CANCEL") || (method == "ACK")) { if (uri != myself) { # Und das Paket entsprechend weiterleiten if (!t_relay("udp:outbound_proxy:outbound_proxy_port")) { log(1, "Not possible to relay\n"); # Fehler melden sl_reply_error(); return; } return; } } [...] ################################################################################################################## # Rest of "normal" Routing logic with number manipulation / Routing to different Gateways / User Authorization/Authentication ############################################################################################################### } Is there any other method, to improve the routing of ACK/CANCEL Messages? I would like to avoid all the number manipulation, checking and choosing of a proper gateway.... I thought, this must (somehow) be possible since from a technical perspective the ACK and CANCEL Message can be associated with a corresponding INVITE Message (and the corresponding Transaction). I've looked in the manual of the TM-Module and found the following example: if ( is_method("CANCEL") ) { if ( t_check_trans() ) t_relay(); exit; } (http://openser.org/docs/modules/1.1.x/tm.html#AEN460) I guess, this example does not mean, that the URI gets rewritten properly and the CANCEL-/ACK-Message would get properly relayed to the destination, where it is supposed to end. Is there any way to do it best? I've seen, that some clients do proper loose-routing for ACK-Messages, but not all clients, so this is not a solution. Are there any other suggestions? Thanks in advance, Carsten ____________ Virus checked by G DATA AntiVirusKit
