Display initial calling number on a device being forwarded the call to

[riderfaiz]

HI everyone,

I would like to ask... currently I am using CM v11.5. I turned on the phone forwarding on my desk phone (8851) so all calls calling to my ext will forward to my cell.

Here is what happen. If someone from outside calls my desk phone number, it will forward to my cell certainly. But the calling number is not displayed as the initial calling number. Instead, it displayed as my company number. How do I correct this?

Example: Caller A with number 415-111-1111 calls my desk phone 650-123-4567.  My desk phone will forward to my cell 408-888-8888. Now on my cell, I get call...but it shows as 650-123-4567 instead of the calling number 415-111-1111.

How do I configure or correct this?

Thank you for your help.

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.  

1. 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. 
2. 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. 
3. 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!

thank you very much for all your responses. I really appreciate it.

We do not use SIP but pstn. I will try to schedule a downtime next week and see if this works.

stay in touch. Take Care at home and stay in good health!

Hi Dalton,

Thank you for the info. I just checked... our gateway that connecting to the PSTN (PRI) is unknown. But some other branches are using H323 that I know. In the gateway (with unknown status) I could not see any mgcp commands...so do you think mostly we are using H323?

I am actually having this problem, but in reverse. My employee would like to have calls fowarded, but does not want to answer every call, "His this is _____ from _____. How may I help you?"

We are not in charge of or have access to the GUI or any software, but would love it if it said our company name instead of a number.

Dalton,  Im having same issue.  Caller ID of original caller not being passed to fwd mbl phone.  Any help would be appreciated.

Dan,

How does your voice gateway connect to the carrier?  (SIP, PRI, Analog)

How does the voice gateway connect to Call Manager? (SIP, MGCP, H.323)

What number is forwarded out to the PSTN?  (forwarded party's number, main number for the site, etc.)

This may be difficult to troubleshoot via the forum here, but I'll try my best to help, sir.

I found by removing the area code and prefix (xxx)xxx from route group Cube. I really appreciate your assistance here.  Tested and confirmed.  All 10 digits of original caller are now passing through to the fwd number.

If your provider of the PSTN connection allows it you could try with enabling send of redirecting number information. Depending on your setup it would be called different things. On a SIP trunk in CUCM it would be “Redirecting Number IE Delivery - Outbound”, select this option and reset the trunk to activate the change. Please bear in mind that this would drop any ongoing calls, so best to carry this out during off hours.

Hi Roger we do not use SIP... but I will try Dalton and Ayodeji suggested then will tell the result.

Thank you very much again! Have a nice weekend.

What protocol do you use in CUCM for your gateway, H.323, MGCP or SIP?

[riderfaiz]

Hi Roger, and everyone,

I just got back to the office today and checked on this. I think I am using mgcp as my gateway does contain any dial plan settings for H323. I am pretty sure we do not use SIP. May I ask how to check for sure? If it is MGCP, what do I need to do to achieve the goal?

Thank you for your help!

Hi Takami,

We should be able to verify this if we log into the CUCM Administration page and navigate to Device > Gateway.  Once you find the gateway, does it state H.323 or MGCP on the right-hand side?

Hi Roger, and Dalton,

My gateway is using MGCP for sure. IF this is the case, where I can change the setting? Thank you!

Hi Takami,

If we click on the T1 interface, we should be able to set the outbound call information as needed, including the Calling Party Selection.  

Please note that the Apply Config/Reset/Restart may drop calls in progress when the config is pushed to the MGCP gateway, so please test after hours.
