CUCM With Skype for business integration

[yazan khamis]

we have both cisco call manager and skype for business options on the table for new implementation and we are trying to get the benefits from both applications,but the only concern for the management is that every user will have two extension number one for cisco devices and one for skype.

So is it possible in any way to have one extension for each user for both cisco and skype at the same time?

For example can i use extensions to call cisco phone users and use address (URI dialing) to call skype users ?

[Chris Deren]

Absolutely, the question is how are calls delivered from outside, i..e which system do they hit CUCM or Skype or both?

[yazan khamis]

Hi Chris,
calls from outside hits the cucm first.
but my questions is:
lets say i have extension 1111 configured on CUCM and on SFB , if i call 1111 from any other extension will it ring both systems at the same time ? if yes please explain on the call flow of this call

[Chris Deren]

You would need to pick which system the call needs to go to/stay when dialing the same extension, you could definitely have outside calls come into 1111 defined on CUCM and internal calls going to Skype, but I doubt you want it like this. It's all in Partitions/CSS configuration.  Your best approach would be to use single number reach configuration to trigger concurrent call to Skype when Cisco extension is dialed, normally you would have different remote destination (DN on Skype) but again with Partitions/CSS you could make it the same.

One issue with this setup that we're starting to see in our environment, is when the call comes in, with the wait time set to 0.0, it forks immediately to Skype. If the user is unavailable, away, offline, or otherwise unreachable within the skype environment, the call can't be completed and if voice mail is configured within Skype, as ours is, the call will be diverted almost immediately from the Skype system, sending a missed call email and cucm will lose the call. 

The other possibility is that the call comes in, forks out to both systems, user answers their desk phone, call dies that was heading to Skype. User then gets a missed call email within Skype. 

I've had to go in and set the wait time to ring this line, depending on the user, anywhere from 5 - 15 seconds to basically prevent issues with this configuration. I have no solution to this other than this.
