Scenario#45: 7841 SIP phone in Registration loop

I was working on this customer issue last week where they added a new 7841 phone but it was not registering properly or should I say it was registering briefly before unregistering. Call Manager was 9.1.2.11900-12 which does not support 78XX phones so customer actually applied the device pack cmterm-devicepack9.1.2.12039-1.cop so that they can addContinue reading “Scenario#45: 7841 SIP phone in Registration loop”

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”

Scenario#28 – CUCM applying DST changes 1 week before needed (2010)

Today was a hectic day. I walked into my office and immediately started getting calls that phones have gone 1 hour behind. I was a bit surprised as Daylight Saving will be finishing here in UK on 31st October so how come phones gone behind a week earlier. I thought may be customer has gotContinue reading “Scenario#28 – CUCM applying DST changes 1 week before needed (2010)”

Scenario#26 – Abbreviated Dial not working Cisco 7912

Created a new Softkey template includingContinue reading “Scenario#26 – Abbreviated Dial not working Cisco 7912”

Scenario#25 – MoH file download from Call manager

Came across an MoH issue for a customer where the file was missing from Subscriber. As you may be aware that an MoH file should always be uploaded across the cluster on each server to work properly. If you only upload the MoH file on Publisher then it won’t be replicated on other servers. YouContinue reading “Scenario#25 – MoH file download from Call manager”

The ISDN-30 link was working fine but they had issues on SIP trunk (how many times I have heard this?) …. their outbound calls over SIP were usingContinue reading “Scenario#24 – SIP Calls drop after Silence”
