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.
I ran the issue that I was unable to import any of my tar files created on OSX stations . So after some digging , I found this article of William Bell who gave me the right solution for this problem :
In any case , don’t hesitate to read this good blog 🙂
I came across your blog when doing some research and its totally great. I have been struggling with getting CUVA to work with our deskphones.
To give you a quick background, we are running UCCE version 7.5. Our Desk phones are 7941’s with the latest firmware (9-1-1SR1S). All deskphones are configured as SIP.
Im running Video Advantage verion 2.2 (which supports SIP video) and cannot get the phone to integrate with the video software. CUVA works perfectly fine with a deskphone. One theory I had was the windows firewall was blocking CUVA from speaking with the 7941 but after disabling it, Im still experiencing the issue.
Is there soemthing major that Im missing, which is causing the webcam to no communicate with the phone?
