to get the phones up and running i hve to modify each Iine id on cucm and remove the " ascii display internal caller id"

i would like to resolve this on a level were all headers are modified instead of each line

How is skype trunk configured? Is it directly with CUCM or with Gateway in between?

there is a gateway inbetween

[Nadeem Ahmed]

I tried couple of thing the options left here

1) blocking clid name but you will see ""Anonymous" instead of name.

2) Lua script on CUCM from which you can modify anything you want through this script.

3) But if you using Cisco Gateway you can perform this changes from Gateway rather than on CUCM which is quite easy than lua scripting.

Hi,

 please, check this link: A guide to SIP Normalization on CUCM and Lua Scripting.

Hope this helps

I really would like to understand better this issue. you are facing The format of the From sip header doesnt look correct to me. I have never seen cucm present anything like this..So can you please post the output of a non working call debug here..

From your cube, please do debug ccsip messages and post the log here. Please include calling and called number..

May I ask what exactly is the issue you are facing?

I am asking so that we may find the most efficient solution for this

[macazarpros]

i will post the logs when im on site.. ayodeji but briefly skype will accept invites only like this 

From: <sip:99051000254750@sip.skype.com

and the cucm presents the invites  with caller id like this:

From: <"M.Alexis" sip:99051000254750@sip.skype.com

so in short it a matter of normalizing the sip headers ...to remove the id.  from the informaiton the guys gave scripting is a good option or sip normalization on the cube.... 

[Ayodeji Okanlawon · Accepted solution]

In that case using lua script is an over kill for this. Its also a steep learning curve. You can just configure sip profile onb the cube here is what you need..

NB: That the format fo the from you posted is incorrect. This is why I wanted to see the logs. The format should be as below

From: "M.Alexis" <sip:99051000254750@sip.skype.com>;tag=43AAA454-1617

voice class sip-profile 1

request INVITE sip-header From modify "From:(.*)<sip:(.*)@(.*)" "From: <sip:\2@\3"

or

request INVITE sip-header From modify "From:(.*)<sip:(.*)@sip.skype.com>" "From: <sip:\2@sip.skype.com>"

Then apply htis to the outbound dial-peer to ITSP

dial-peer voice xxx voip

voice-class sip profile 1

[macazarpros]

this option 1.request INVITE sip-header From modify "From:(.*)<sip:(.*)@(.*)" "From: <sip:\2@\3"

worked great... excellent im starting to see its all about mixing and matching accurately.
