Scenario#41 – No Ringback tone from H323 Gateway going to SIP trunk

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. There was no ring back tone and no automated messages before an agent picks up the call. The call flow was something like this: PSTN > ISDN30 > H323 Dial-peer > SIP Trunk > 3rd-party Contact Center Equipment First I thought it could be the third-party … Continue 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 which I found after getting several requests from customers. If you are among one of those who is annoyed with this then following is the procedure to get rid of it. You will need Admin rights on Call manager to make these changes. Create a new … Continue 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 issue – CSCtx66554 & CSCtt03265 which is affecting C200/210 series and there is no fix as of yet.

Have a look at the workaround and it may fix the issue but if not then you can Order a replacement from Cisco.

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 designed in a way that when they dial any 7614XXXX extension, it hits a TP (7614XXXX )and gets translated to 60447614XXXX. For testing we dialed several 7614XXXX numbers and they all went fine to corresponding 60447614XXXX except when they dialed 76146920. As soon as they dial … Continue 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. not assigned to any phone or any extension mobility profile No Extension assigned to the phone The Busy Trigger and maximum calls on the line are not correct (normally you configure max calls: 4 and busy trigger: 2) For this particular issue I found no … Continue reading Scenario#37 – Phone display “Error Pass Limit”

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 to Bulk Admin > Phones > Update Phones > Query and then if you want to search all of them just hit ‘Find’. This will bring all the phones in the system. Scroll down and hit Next you will see a screen similar to this: Don’t … Continue reading Scenario#35 – How to logout in Bulk from Extension Mobility?
