Hi Takami, There are a few possibilities here and it may require a bit more information to give a full answer; nonetheless, please find a few things to check below and let me know what you find.   In the CUCM Admin page, check under Call Routing > Route/Hunt > Route Pattern for the patterns used for PSTN calls to the cell number ( 650-123-4567).  If your call forwarding on your extension begins with a 9 or 91, the Route Pattern could look something like 9.[2-9]XX[2-9]XXXXXX or 91.[2-9]XX[2-9]XXXXXX.  If your PSTN gateway is a CUBE for example, run a SIP debug (debug ccsip messages) and make a test call to recreate the scenario.  Check to see if the Diversion header is included with the original calling party number.  If so, we can use a SIP profile to copy the Diversion field into the From: field of the SIP INVITE.  Check to see if the "Redirecting Diversion Header Delivery - Outbound" setting is enabled on the SIP Trunk to your CUBE. I look forward to helping you resolve this issue!  Please rate this post if it is helpful.  -Dalton Woolsey ... View more

Great post Michael.  +5   I ran into this scenario when upgrading from 10.5.2 to 12.5.1.  After issuing this command on each IM&P node, the services started within 5 minutes. No reboot required. ... View more

Hello,   In later versions of CUCM, such as 11.5, this issue can be resolved by unchecking the Selfcare checkbox under the Restore Components.  Unfortunately I cannot comment on the CUCM 9.1 cluster.    Hope this helps someone else in the future!    Regards,   Dalton Woolsey ... View more

Hi Rakesh,   As others mentioned this is almost certainly a clocking issue. Were you able to get this resolved?   Are there multiple PRIs?  If so, are all of the PRIs taking Slips & Errored Secs or just one of the PRIs?  What model of router?   Regards,   Dalton Woolsey ... View more

Hi Abdulkarim041,   In certain scenarios in which VMWare tools does not want to install, I have had to change the OS mode to Permissive, then try installing VMWare tools via vCenter GUI.    1. Open CLI to Unity Connection node 2. Run the command "utils os secure permissive" 3. Attempt to install VMware tools 4. After successful installation of VMware Tools, change the OS Mode back to enforcing 5. Run the command "utils os secure enforce"   Regards,   Dalton Woolsey   Please rate all helpful posts.   ...

Shohamshalom, You need to apply a Normalization Script on the SIP Trunk which will modify the SIP Header and change ANONYMOUS / NONE / NULL to a "Replacement Number" which will be routable by CUCM.  Please find the SIP Trunk Normalization Script details below. Name: Allow-Anonymous-Calls Description:ALLOW ANONYMOUS / NONE / NULL INBOUND CALLS - Change the SIP invite from sip:Anonymous to sip:0 so that calls match the inbound call filter list Conetent: M={} --change to trace.enable() to have trace output in SDI trace.disable()   function M.inbound_INVITE(msg)  --capture inbound INVITE messages    --set the string to replace the anonymous, unavailable or restricted strings in the INVITE message    replacementNumber = "sip\:0"    trace.format("Replacement Number: %s", replacementNumber)    --Set the header values to inspect for anonymous caller    local fields = { "From" , "Remote-Party-ID" , "P-Preferred-Identity", "P-Asserted-Identity" }    local numberOfFields = #fields    trace.format("Fields/Count: %s, %s, %s, %s, %s", fields[1], fields[2], fields[3], fields[4], numberOfFields)        --loop though the header fields to inspect and replace any instance of 'anonymous' with the specified replacement number    local x = 1    while  x <= numberOfFields do       --get the field from the header       local header = msg:getHeader(fields[x])       if header == nil       then          trace.format("Field %s not found", fields[x])       else          trace.format("Field %s: %s", fields[x], header)          --does the from contain anonymous          if string.find(string.lower(header), "sip\:anonymous")            then             trace.format("Found string anonymous in %s", fields[x])             trace.format("Header: %s %s", fields[x], string.lower(header))             --replace the word anonymous with the user defined replacement number            local newHeader = string.gsub(string.lower(header), "sip\:anonymous", replacementNumber)            trace.format("New %s Field: %s", fields[x], newHeader)            --modify the From field            msg:modifyHeader(fields[x], newHeader)              else if string.find(string.lower(header), "sip\:unavailable")          then             trace.format("Found string unavailable in %s", fields[x])             trace.format("Header: %s %s", fields[x], string.lower(header))             --replace the word unavailable with the user defined replacement numbe            local newHeader = string.gsub(string.lower(header), "sip\:unavailable", replacementNumber)            trace.format("New %s Field: %s", fields[x], newHeader)            --modify the From field            msg:modifyHeader(fields[x], newHeader)              else if string.find(string.lower(header), "sip\:restricted")          then             trace.format("Found string unavailable in %s", fields[x])             trace.format("Header: %s %s", fields[x], string.lower(header))             --replace the word unavailable with the user defined replacement number            local newHeader = string.gsub(string.lower(header), "sip\:restricted", replacementNumber)            trace.format("New %s Field: %s", fields[x], newHeader)            --modify the From field            msg:modifyHeader(fields[x], newHeader)                           else             trace.format("Field %s number valid.  No change made.", fields[x])           end           end           end         end     x = x+1    end end return M   Script Execution Error Recovery Action : Message Rollback Only System Resource Error Recovery Action:   Disable Script Memory Threshold: 50 LUA Instruction Threshold: 1500     Once creating the SIP Normalization Script in CUCM under Device > Device Settings > SIP Normalization Script, apply the script to the SIP Trunk after hours.  Ensure to Apply Config & Reset the SIP Trunk (NOTE: This will drop active calls).  I have tested this in multiple deployments and verified it works.   Regards,   Dalton Woolsey ...
