I am facing problem with mobile connect timers setting.
Consider the scenario...i am in canteen some one dials my ip-phone no. i get a simultaneous call on my mobile also....now i reach to my desk while talking on my mobile and now i want to transfer the call back on my IP-Phone. Now in this scenario when i cut the call on my mobile it takes around 30sec for me to resume the call back on my IP-Phone.
Do i am missing any thing here?Pls let me know if any one has solution for this..CUCM version is 7.x
thanks in advance
We sometimes see strange delay and ringing issues like this when the call to the cell phone from CUCM (SNR call) is sent over an unsupported link:
"Mobile Connect features do not get supported for T1 CAS, FXO, FXS and BRI."
Please make sure you are using a PRI, H323 GW, or SIP trunk from CUCM to the cell phone. Using a different type of trunk will cause unexpected behavior.
I am using E1 PRI link..and protocol is MGCP.
consider the following scenarion:
IP-Phone calling Mobile Phone
After conversation mobile user disconnect the call, but still call is flashing on IP-Phone for 30 seconds.
So the timer is same in both the cases. Can we reduced this timer some how.
Since you're using MGCP this command won't work. MGCP back-hauls ISDN messages to CUCM so you have to enable it there. Go to CallManager Service Parameters, click on advanced and in Clusterwide Parameters (Device - PRI and MGCP Gateway)change Convert Progress to Disconnect for User Side PRI EURO to True. Not sure if you need to restart the CCM service.
I am not getting any such option in my CCM.
My CCM version is:
System version: 184.108.40.20600-5
However there is a option of "Convert European Progress Message to Alerting" whose current valuse is false.
I set it true and reset the MGCP gateway but still it is not working. Its still taking 30 seconds.
I have read in Cisco documents that 30seconds is default behaviour in SNR.
So does it mean that it can't be changed.
This is what Cisco docs saya about the problem.
Q. Why does the desk phone stay in the Remote In-Use state for up to 30 seconds
after the user hangs up the cell phone?
A. After hanging up the cell phone, the calling party hears the reorder tone and
the desk phone stays in the Remote In-Use state for up to 30 seconds before
moving to the On-Hold state. The desk phone can then resume the call with
the calling party. The delay occurs because the mobile carrier waits before
sending a disconnect message to Cisco Unified Communications Manager,
probably to avoid false disconnects.
WE had the same issue and found out that CUCM and ISRs keep the call active for 30 seconds is they receive a disconnect with PI in it, which actually quite often.
Did you click on the Advanced button in the service parameters section? If you don't click Advanced you won't see that option!
After clicking the Advanced button i got the option.
I set it true and reset the MGCP gateway.
But still it is taking 30 sec. Do you want me to send the router configuration?
or do i need to do any other thing after changing the parameter.
