As seen in your debug the connection does not get established and is not authorized:

401 Unauthorized

Are you sure you have corrent username and password in your sip-ua config?

It doesn't change the sip header directly, it just change your calling id number, for example from my extension 1306 to

99051000001534, that way when your call match your skype dial-peer, Skype will accept your call because your are using the number (example: 99051000001534) as your CLID, that is what Skype is expecting to receive.

Hi Chris,

  Thx to reply, maybe credentials is not correct, I debug ccsip info saw that:

//36/000000000000/SIP/Info/sipSPIHandleAuthChallenge: Invalid Username or Password

In your opinion that config is OK without User/Pass?

I never tried connecting to Skype, but I doubt they would allow connecting without authenticating.

Hi

I read (well... scanned over half-heartedly) a document from Microsft the other day that described how to set up a connection from MS Lync to Skype.

The solution basically involved putting in an Asterisk server, which ran a custom developed interface of some sort to Skype. So call went from Lync to Asterisk, to custom code to Skype. Suggests to me that connecting to skype is a little more complex than a simple SIP trunk.

Hi,

This can work with a normal SIP trunk in your voice gateway, I configured this for two of our customers. So, first of all, can you ping sip.skype.com?..Also, can you check in your skype manager that you are using the username/password authentication method (also check if your password and SIP user is the same configure in your router).

Hi Chris,

  User/Pass incorrect,  change another accout it can registered.

99051000154290@sip,skype.com, that URI i think is regular to make a call.

What if behind CBUE, has a CallManager of IP Phone something, how  can i modification the sip header make behind CUBE device can use the  regular format outside call?

Hi, you can use translation rules to change your calling number ID. I use to change this way:

voice translation-rule 1111

rule 15 /^....$/ /99051000001534/

voice translation-profile Skype

translate calling 1111

dial-peer voice 101 voip

description Skype Outgoing

translation-profile outgoing Skype

destination-pattern 9T

voice-class codec 100

session protocol sipv2

session target dns:sip.skype.com

dtmf-relay rtp-nte

no vad

So everything that comes with a 4 length digit can be converted to the SIP user number

Hi Gabriel,

  Did you mean translation-rule can change the sip request header like:

"From: <>99051000154xxx@sip.skype.com>"?

  Cuz i saw some doc using "voice class sip-profile xxx", some like that pattern:

voice class sip-profile xxx

  request INVITE sip-header From modify "sip:(.*>)"  "sip:99051000154xxx@sip.skype.com>"

And use in "voice service voip" or "dial-peer".

If translation-rule can do that it will be nice, cuz i am not skillful for "voice class sip-profile"
