SIP Normalization

by | May 21, 2012 | CUCM, SIP

Hi ,

Recently , I had to configure a SIP trunk to operate with Microsoft Exchange as voicemail system but as the integrator of the exchange doesn’t know a lot about his system , he was unable to configure the voicemail boxes with the correct number so it gave me some mistake as Exhange was unable to resolve the  called number . So after some searches , I found that we can use the SIP Normalization as in the CUBE but this time directly in the CUCM .

The SIP normalization for SIP trunk on CUCM is based on lua ( an old application language) but even if you have no complex structure , you can easily modify the SIP stack in the inbound and outbound direction.

So you need to read the cisco documentation to master but after an half day you can already play with it to have something.

Lua is really something that you need to try when you need to update a little your sip fields/option and which is really powerful . I will come on later on this post to put a short example.

Here are some stuff regarding the UCCX .

First of all , please check that under the menu Subsystems>Cisco Media , you have well CTI port defined. It is depending on your license.

For reminder , the JTAPI User is the user which will control the CTI Route Point and the CTI Ports ( Everything must be populated via the appadmin).

Jtapi User

The RmCM user is the user which must control the agent extension and the supervisors. Don’t forget also to define under your agent/supervisor agent the primary line and the IPCC extension.

RmCm User

Define then the Telephony Call Control Group that you will use to define the amount of CTI ports that you will use for your script/applications. Don’t forget to click on the Show More button in order to configure correctly your ports

Call Control Group Definition

In your application script , the Maximum Number of Sessions has to match the CTI port that you have defined in your call control group. If it is not the case, then you can encounter the conditions where you will hit the default script message so the message “Sorry  we are experiencing ……”.
