Now I have found a settings in CUCM (11.5), but I am not sure related:
"If you are connected to a low-bandwidth network and finding it difficult to take an incoming call on your mobile device, you can set the system SIP parameters to improve the condition. Increase the SIP Dual Mode Alert Timer value to ensure that calls to the Cisco Jabber extension are not prematurely routed to the mobile-network phone number."
The default settings was 1500 ms, now increased to 10.000 but I am a bit unsure as we are not using the related Mobile Connect (now Single Number Reach) feature.
We have to test it.

Hi,
Yes, configured to receive calls from inside CUCM, and from outside.
There is a public PSNT number field mapped to DN-s.

Hi
We have a fully working Jabber Mobile MRA installation when connecting internet over wireless (wifi) networks.
But when connection via 3G or 4G mobile network, some calls cannot arrive to jabber.
Tried to find any timers related to a delayed connection setup, but cannot find any.
Is there any SIP or other CUCM timer - that we can set - to make our system works over mobile networks?

Hi,
To tell the true - I cannot found any interesting at log. Attached it.
The time when we see a missed call notifocation (as the only one) at client side is:
2018-05-25 11:59:23,164 INFO [0x00000001b4fb2b40] [miscs/YLCLocalNotificationManager.m(379)] [UI.Action.System] [-[YLCLocalNotificationManager sessionDidEnd:]] - jabber post a notification[You have missed a call] at 2018-05-25 09:59:23 +0000

No, there was not 183 Session in progress, just 180 Ringing - at the successful call.
When call was unsuccesfull, there was not any 180 ringing back, and CUCM send CANCEL .
If it is a timer, it just occured at mobile calls, as wirelessly connected Jabber clients working definitely well.
Please take a look to the following diagrams (from CUCM trace)
The successfull call was the following:
The Cancel at 11:59:28 is when the caller on-hooked the phone. So this CANCEL was occured by tester staff.
But at the unsuccessfull call, there was not any ringing back, and maybe the Callmanager send a Cancel at 11:59:20 , eight (8) seconds earlier as caller on-hooked call. So this CANCEL was not occured be test-staff, it is occured by Callmanager.

Hi,
We have implemented an Expressway MRA system with CUCM 11.5.
Clients are Android mobile client with newest Jabber. All of clients connecting via MRA (ExpE-ExpC).
When client connected to wireless network (still MRA, over ExpE-ExpC), all of calls will be successful.
But when connected to stable 4G network, sometimes the client cannot ring, just display an "Unanswered Call" notification.
Tried to debug at CUCM/Expressway pair - and I can see that CUCM sends an
- INVITE
- Gets back a Trying from ExpC
- after that sends a CANCEL
Just a note, not all of the time this issue is occured. Sometimes yes, sometimes not.
What could be caused this issue? Why CUCM send Cancel before receive Ringing and 200OK?
Is it a timer? The SIP profile in CUCM is "Standard SIP Profile for Mobile Device" with default values:
(attached)
I assume the internet connection is stable - as CANCEL arrived in time to client.

Just note:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvd06182
"In AnyConnect 4.4, ConnectionData.xml was moved from ProgramData to AppData (Windows). When upgrade from any older version to AnyConnect 4.4 happens when the posture lease hasn't expired, AnyConnect 4.4 is not able to the find the connectiondata.xml. Hence Discovery fails after upgrading to 4.4 during posture lease."
As I can see, the description is the same in bug and in you post, so assume you have opened the ticket :)

How does the ISE server found policy servers?
With URL redirection or with previously connected PSN-s from Connectiondata.xml?

Hi,
We try to implement ISE 2.1 posture with Aruba Controller/AP.
Does anyone have any experience how can we do it?
We use EAP-chaning, certificate auth for Machine, and password auth for user.
We can change the Role (from guest to Authenticated) with Aruba-User-Role Radius answer, we can send CoA, and normally we can
succesfully manage the posture.
But - if user logged out from machine, and revert to Role back to Restricted (with succesful machine authentication),
and try to login again, the Aruba WLC (Assume the PMK caching) says " Setting cached role to guest for user <MAC>” , and the posture will not occured,
and the user stuck in Guest role despite of successfull authenticaton.
What is wrong with this? The ISE 2.1 Compatibility Matrix shows Aruba as supported OS.

I am afraid, this settings is another thing.
It changes the diplay of Called side, but I need to change the _Calling_ disply to show the name of actually ringing member of hunt list.

Hi,
Server is Callmanager 11.0, protocol is SCCP, Hunt list is configured, and used when the single extension is not answering.
The question it : Is it possible to display the name/extension of the hunted _ringing_ phone at the Caller phone ?
Caller calls 131 --> Busy / Hunted to 7131 -> Hunt list contains one entry (181) -> Phone 181 is ringing.
At this stage the Caller see the following at his/her phone: "Helpdesk 7131" (Alerting name of hunt list)
but wants to see number 181 and the name of this extension. Once again, at the ringing stage.
When 181 off-hooked phone, the caller see the righ name.

Well,
Try from here to ask a question ;)
So posture.
Our customer have SEP (Symantec Endpoint Protection). Somewhere in this forum I read about it: for remediation in SEP we need administrator account in local computer . Is it true?
By the way - are you suggest to set most of reqirements (like SCCM, AV-AS) Mandatory or optional?
Our experience with AnyConnect (also like with NAC client a few years ago ;) is that setting requirements to Mandatory is a very dangerous thing if business continuity is a bit important ...

If remember well,
if your network change, windows made an NCSI test (Network Connectivity Status Indicator),
with a DNS and a http request. This test forced your browser to pop-up a window.
I think you have three choise:
- if the machines are managed by you
1, you cah switch off this feature. In this case you lost the windows internet detection feature
2, you can change the address pointed by default to http://www.msftncsi.com (several ip) to a simple outside ip, and after you have an entry at the redirect ACL to allow traffic to this ip without redirect
If machines are outside of your control
3, you can build a complex redirect acl, witch will allows traffic to the ip resolved by www.msftncsi.com. I have a large collection from a crontabbed gethostbyname (attached) , it has 246 entry, but you can reduce it to 4-5 bigger subnet. I think it not a big risk to allow this traffic when redirect is active.
