Problem with Skype SIP connection

Recommended Posts

We have one of those Skype SIP Connect lines into our system which has been working fine for several months. All of a sudden, it's no longer registering and we're getting this in the log:

 

[1] 2011/06/07 22:03:34: TCP: TOS could not be set, code 0

[4] 2011/06/07 22:03:34: Certificate for VeriSign Class 3 Public Primary Certification Authority - G5 not available

[5] 2011/06/07 22:04:06: Registration on trunk 5 (SKYPE Connect) failed. Retry in 60 seconds

 

In the certificate screen I have this:

 

VeriSign Class 3 Public Primary Certification Authority - G5 Rejected Root CA for server authentication

 

I've tried deleting the cert but it just reloads it when it next registers.

 

I'm all out of idea - any suggestions?

 

Thanks,

Kenny

The registration failure indicates that PBX received either an error from the provider or PBX could not reach the provider (timeout scenario). The PBX SIP log (or wireshark tracing on the PBX) would give some clues regarding why this is failing.

Well obviously Skype turned on TLS transport layer (great thing) and use a certificate signed by VeriSign (also a great thing). What you need to do is import the VeriSign Root in the certificates section of the PBX (see http://www.verisign.com/repository/roots/root-certificates/PCA-3G5.pem). I hope it is the right one.

The latest version which has been released just before Christmas should have the certificate built-in. If you upgrade, make sure that you delete all certificates from the list of certificates or just remove the whole working directory (at least the certificates directory) from your install before restarting the service.

 

If you get 404 the problem might be a different one. Maybe you are subscribing to the wrong number. Lets see if we can come up with an updated description on how to connect snom ONE to Skype.

The latest release on http://wiki.snomone.com/index.php?title=Upgrades shows the last one was released in November, is there a new spot I should be looking?

I am running 4.5 and having the same issue with skype, the certificate is not preinstalled, the one above did not work, I downloaded from http://www.verisign.com/support/roots.html I still get 408 Request Timeout (Registration failed, retry after 60 seconds) under certificates I get VeriSign Class 3 Secure Server CA - G3

 

Rejected Root CA for server authentication, although I have a valid certificate with the same name.

log

Certificate could not be verified

We are having similar certificate issues.. but using a SoHo.. for which the alpha monocerotids release has not yet been made available (running 2011-4.3.0.5021 Linux). Can 'Pradeep' (?) or someone post or PM a certificate set that will allow this to work?? Many thanks for your kind attention.

I remember that our QA has skype trunk working in the lab. Not sure if Skype really supported TLS (even though the documentation says so). We will double check that.

 

BTW, did you check out this forum link - http://forum.snomone.com/index.php?/topic/4827-skype-connect-seems-to-be-not-compatible/page__p__21206__hl__skype__fromsearch__1#entry21206
