Jabber mobile with MRA - issue over cell network

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?

Have you configured the TCT/BOT devices for these users that have issues receiving calls on their mobile devices outside of your production network?

Hi, 

Yes, configured to receive calls from inside CUCM, and from outside.

There is a public PSNT number field mapped to DN-s.

1. Tried with iPhone SE (ver 11 - latest ), and with different Android versions - but generally newest android phones.

2. Yes, seen on different devices

3. Yes, we have set all of the required energy (and other)  settings to stay it alive.

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.
