One of our customer reported an issue with ring back tone when calling their Contact center. I made a test call and observed that as a caller when you call their main Contact center number all you hear is dead silence and then when agent picks up the phone you could hear them talk. ThereContinue reading “Scenario#41 – No Ringback tone from H323 Gateway going to SIP trunk”

Scenario#40 – Access Personal Directory/FastDial without PIN
You may have come across this that though you are logged into your profile through Extension mobility but when you try to access your “Personal Directory” you will be prompted for a userid and pin. Unfortunately, this is by design and cannot be changed. There is a workaround to escape entering userid and pin whichContinue reading “Scenario#40 – Access Personal Directory/FastDial without PIN”
Scenario#39 – CIMC of Cisco UCS C210-M2 showing false alarm
I was looking into a case for one of very high profile customer where their CIMC (Cisco Integrated Management Controller) was showing PS Redundancy status as ‘lost’. However, both PSU were up and Normal. Have a look at the screenshot below: By searching through Bug Tool kit I found two bugs for this particular issueContinue reading “Scenario#39 – CIMC of Cisco UCS C210-M2 showing false alarm”
Scenario 38# Call Routing Issue – Intercept Pattern
Had a bizarre issue with one of the customer where they were trying to dial an internal extension and it was going to a mobile phone. There were no CFA/CFNA/CFB set on the extension itself but for some reason it was following this path. The Call manager version was 6.x. The call routing was designedContinue reading “Scenario 38# Call Routing Issue – Intercept Pattern”
Scenario#37 – Phone display “Error Pass Limit”
A customer reported an issue with their 7941 phone. The issue was they plugged in a new 7941 all configured at Call manager and it was showing “Error pass Limit” as follows: This sort of error normally comes when you have one of the following conditions: Too many unassigned directory numbers in Call manager i.e.Continue reading “Scenario#37 – Phone display “Error Pass Limit””
Scenario#36 – RTMT Alert LSIESG_AlertIndication 500605B00177F4C0 BBU disabled
I was looking at some alerts for a customer when I found this in RTMT: At Thu Mar 01 04:42:41 CET 2012 on node 10.254.33.20, the following HardwareFailure events generated: hwStringMatch : Mar 1 04:42:10 AKDEUC00 daemon 4 Director Agent: LSIESG_AlertIndication 500605B0024A5360 BBU disabled; changing WB virtual disks to WT Sev: 3.

Scenario#35 – How to logout in Bulk from Extension Mobility?
Recently we had a customer who asked if there is any way they can logout all users from extension mobility at the same time? There is no straight forward answer if you google it so I thought to compile this post for a quick reference. You can do this from Bulk Administration. Just browse toContinue reading “Scenario#35 – How to logout in Bulk from Extension Mobility?”
Scenario#34 – Cannot make International Calls from US gateway
One of our customer has multiple sites across the globe including sites in UK and US. Their initial design was to send all UK calls from US over a SIP trunk to break out from a UK gateway for LCR (least cost routing). For some reason they stopped using that trunk and configured local dialContinue reading “Scenario#34 – Cannot make International Calls from US gateway”
Scenario#33 – Phones not registering CUCME
Interesting case today. I had a call from customer saying they had a power cut and when the power was restored all their phones went into ‘Registering’ status. I initially thought it could be a network issue from switches to CUCME gateway as the config was looking fine to me. I did a show ephoneContinue reading “Scenario#33 – Phones not registering CUCME”
Scenario#32 – SIP Calls drop after 75 minutes
I had an interesting case where SIP calls over a SIP trunk were dropping after like 75 minutes. The duration was not confirmed as sometimes it use to drop even before 75 minutes. I looked into few CCSIP debugs (debug ccsip messages) and found that the ‘BYE’ message was actually coming from our end (CallContinue reading “Scenario#32 – SIP Calls drop after 75 minutes”
