SV9300 - Call Forwarding-All Calls

MAHARAJAH

Greetings
I tried to set the system phone to forward all calls.
When set accordingly, the settings on the PBX are prescribed. CME600.
When trying to call from a cell phone, redirection does not happen. When calling from an internal phone, everything works as it should. Changed devices, the behavior is the same.
Tested on other lines (numbers), everything works as it should.
What can be the problem? Why there is no redirection when setting a parameter in CME600. What can influence this? Please forgive me in advance, I have not worked normally with PBX before.

The following settings were different when compared to a “properly” working number:
1204, 1212, 1213, 1224.
 
Ok so Cmd 1204 being different means we are talking about a different tenant and the settings for multiple things can be different on a tenant by tenant basis. A quick check would be to change 1204 for this extension to the same as a working one and see if it then works. Note depending on the type of lines you are using, you may also need to change 1212 and 1213 in order for this to work as the CLI will be different and may be rejected by the carrier.

Commands worth a check include but are not limited to Cmd 65, service features can be set here, Cmd 78, in case split call forwarding is set up and Cmd 8A, as the LCR may not be set up correctly for this tenant.
 
Thank you for the feedback and I apologize for the short response. It takes time to sort out and read up on the directions you have given me.

I tried changing 1204, 1212, 1213 at the same time. The result is the same. There is no forwarding from a cell phone.

1213 is also prescribed 11, what is this parameter has not yet been analyzed. I only noticed that if it is set by default, then when calling to other external phones is displayed our one common phone, if you put 11, it is displayed that is specified in 1212. Under the idea is only responsible for the display.

If you take the information on the blade, the number of interest is included in the
11 tenant.
RSC - RCA - full access
SFC - also similar to the “working” numbers.

I went into CM65.
Compared tenant 01, which is the default and 11.
Didn't see any difference. The settings are identical.
All settings are set to 1 except 6529, which is responsible for day and night mode, or day/night/A/B.

In CM78, I checked tenant 11 and 1. Empty, there and there.

With CM8A I will deal as soon as I read the manual, it's not clear what's going on there.

But in general, the phones themselves are set up a bit strange for me by past specialists.

For example:
Internal phone 1000.
I have now assigned XXX-XX-33 to it in 1212
He originally had XXX-XX-99 prescribed in 1212.
But when calling XXX-XX-33 before the change, it rang as well.
When CME600 to another internal phone, for example 4200, what I described in the first post happens.
From internal phones forwarding goes, but from the cell phone calls this device itself.
And CM7601 X33 gives the internal phone 1001 (it is also tied to it (so it should be)).
CM7602 gives 42A7 (I understand that this is a virtual number, which contains the group 4207, 4217, ..., 4297.This is a guess, haven't gotten to the manual and settings yet)

I haven't yet figured out if there is somewhere to see how many external phones are tied to an internal phone. Commands 7601, 7602, 1212 - only work for a single phone binding. Maybe these bindings have some effect, but I'm afraid to touch them yet, because there are many bindings that may be affected by my manipulations.

Make sure in CMD 36 route to route connections are allowed.
Thanks for pointing out the direction. I will study the instructions in this part. It is still unclear where to look for the phone and its binding in these settings.
 
is 1202 the same for this extension as the others?
I'm a little confused about the terms.
In the blade, if you take the information, there are designations RSC(Day) and RSC(Night). And the parameters SFC A, B, C.

From the manual:
RSC (Day)/(Night) field
Select the trunk restriction class of each station:
- Unrestricted (RCA)/Non-Restricted 1 (RCB)/Non-
Restricted 2 (RCC)/Semi-Restricted 1 (RCD)/Semi-
Restricted 2 (RCE)/Restricted 1 (RCF)/Restricted 2
(RCG)/Fully-Restricted (RCH) (default: Unrestricted
(RCA))

SFC (A)/(B)/(C) field
Select the service restriction class A, B or C of each station.
- 00 to 15 (default: 15)

In 1202 - Service Restriction Class A, B. I understand this is SFC (I don't understand where the letter F in the designation comes from) And why there is also parameter C on the blade, but in 1202 it is not there.

To answer your question - yes, there is 15 everywhere, as well as most other numbers. I'll need to do some work on my own to further localize the problem before further asking for help here. Thanks.

I could be wrong, but I think I ruled this out when I changed the tenant to one that has a phone that redirects external calls when the CME600 is set to normal.
I take it that command 36 is related to this.
When I reverted back to the line settings, I wrote the necessary tenant permissions both ways in command 36.

I don't understand the very fact why the device, on which call forwarding is installed, starts ringing itself when external type of calls, and does not drop the call, for example, if there is some error.

Could you tell me more specifically where I can see the settings of the line of interest in CM8A? It looks more like general settings, some of which were checked by entering the tenant in which everything worked fine.
 
I'll clarify the information, I was incorrect before.
Boss-Secretary system.
I had it forwarded to the supervisor's phone. And the external call transfer worked.
Is there any way to realize this without the manager's phone?
It is not an option to manually set it on the PBX every day.

To summarize.
One and the same external number “hangs” on the Manager and the Secretary. The Secretary has a “line” in the “secretary” mode.
When CME600 is set on the Secretary's phone, only internal calls are transferred.
When CME600 is set on the Supervisor's phone, all calls are transferred.
It is necessary to make it so that only the Secretary's phone will transfer external calls, because it happens that the Manager stays after work and he needs his phone in normal working mode (although I am beginning to think that this is against the logic of this Boss-Secretary system and an attempt to separate the functions of one whole into 2 different parts).
 
Thanks for your help.
Solved my problem.
On the Boss's phone in 602 I entered not the number I need, but the Secretary's phone again.
That is, in idea, it is on the external circuit it works the call on the command 1312 and on the internal redirect with the command 602. (double configuration by human logic).
And already the Secretary as intended makes redirection of all calls to the third number and all is well.
The only thing is that the transfer is by 602, not by 600, but you can customize it with the command 607 to be similar to 600. In this system, in any case, all the phones fly to the secretary, and going home she herself every time makes redirection to the third phone. So no one suffers with this scheme.
