Can't call any German Toll Free numbers through Voxalot
Hello,
I'm facing a problem dialling German toll free numbers (49800xxxxxxx) when using ENUM lookup in a Voxalot dialling rule. All toll free numbers resolve to sip:49800\1@sip.pbx-network.de The error message I get is 407: Proxy Authentication required My first thought was that pbx-network.de requires authentication and provides the termination of these calls only to their customers, so I posted to the e164.org forum about this issue. German Toll-Free Numbers: ENUM resolves to sip:49800\1@sip.pbx-network.de evilbunny, the mod of this forum, whom I also sent a logfile showing this error message pointed out that the root cause must be within Voxalot. When calling the toll free number directly (sip:49800xxxxxxx@sip.pbx-network.de) the call wents through properly. Now my question to the Voxalot Team: Can you find out the root cause for this issue? Here is the trace: Code:
20:35:48,668: R: 85.17.19.194:5060 (UDP) SIP/2.0 407 Proxy Authentication Required Via: SIP/2.0/UDP 91.65.142.163:62961;branch=z9hG4bK8043384ff162dc118388005056c00001;rport=62961 From: XXXX XXXX <sip:77xx60@voxalot.com>;tag=752182771 To: <sip:49800xxxxxxx@sip.pbx-network.de>;tag=83b87204c57d64485dbe3bb7601319d3.ba9b Call-ID: 8043384F-F162-DC11-8387-005056C00001@91.65.142.163 CSeq: 13 INVITE Proxy-Authenticate: Digest realm="voxalot.com", nonce="46ed78b65994af68d96e87e08f0b71513c17013d" Server: OpenSer (1.1.0-notls (i386/linux)) Content-Length: 0 Warning: 392 85.17.19.194:5060 "Noisy feedback tells: pid=20805 req_src_ip=91.65.142.163 req_src_port=62961 in_uri=sip:49800xxxxxxx@sip.pbx-network.de out_uri=sip:49800xxxxxxx@sip.pbx-network.de via_cnt==1" cheers, gambrinus.

The authentication digest is "voxalot.com" which means that Voxalot is challenging your end point for credentials.
If you look at the "From" address it is a voxalot.com URI My first question is whether or not your ATA / Device is authenticating with the Voxalot server properly? Quote:

Hi Martin,
thanks for your quick response. I'll quickly explain how to reproduce the issue. This is my setup:
Any ideas? I have cancelled my fixed line, it will be switched off on Friday... If needed for testing: I own such a German toll-free number, but it is already registered with e164.org and the SIP-Route points to my Voxalot account, so it is currently the only number that works for me... :-( Thanks for your efforts, gambrinus Last edited by gambrinus; 09-18-2007 at 09:20 AM. |

Just tried this scenario using x-lite and after dialing:
08001234567 I got a German announcement repeated twice followed by one in english: "The number you have called is not in service. Please check the number and try again" Very interesting. From the same ATA does dialing *393613 get you to the FWD echo test OK? Does 18005551212 get you to the TellMe directory assistance? .

Hi Martin,

Yes, although I have to dial 0018005551212 (since I have setup Voxalot Dial Plans according to German numbering plan; 00 is the access code for international calls). When testing this number at the Dial Plan Test I get: A call to:0018005551212 will get forwarded to sip:18005551212@tf.voipmich.com So ENUM generally works for me and I use it very often since I've registered all my family and friends numbers with e164.org Just with German Toll Free numbers I still get the 407 Proxy authentication required error message, both using softphones (Gizmo, PhonerLite, X-Pro) and my ATA. When registered to my Voxalot account even when dialling the SIP URI (sip:498003301000@sip.pbx-network.de) I get the 407 message! I'm really running out of ideas... Maybe it makes sense to have a look at the server log files to see what's happening. Thanks a lot for your assistance, gambrinus |

For the benefit of everyone:
With joint efforts (thanks to Martin from Voxalot and Lorenz from PBX-network!) we finally found the reason for this issue (affecting all proxy services, not Voxalot only): If a PBX-network customer registers his account with a proxy service all other users of this service will be challenged for authentification (407), which of course will fail. PBX-network will workaround this issue in the next few weeks. Will keep you updated. Regards, gambrinus |

I know you have a solution coming but I had a similar problem with another freecall provider, have you tried setting up PBX as a VSP in your voxalot account. Put sip.pbx-network.de in as the host name and anything for the username/password as they should not matter.
Now set up a dial plan to route the calls to this VSP. e.g route to 498001234567 and use PBX VSP as you set up earlier. Turn off enum on the dial plan. Not promising it will work but worth a try Last edited by chatalot; 11-13-2007 at 05:19 PM. |

Well I have a working route for 49800 but others might not. That's why I try to solve the problem at its root. For everyone.
