Cannot Forward SRST Incoming-Calls to a Specific DN

[aal-sulais]

I'm trying to forward all incoming calls to the SRST to the operator extension, but with no luck. I have SRST with FXO ports. Calls from IP Phone to outside work fine. But when calls are coming from the PSTN to the FXOs, they cannot be forwarded to any extension (even if the caller tries to dial the extension after the line goes off-hook). I'm using MGCP for the FXOs. I have the following commands in the call-manager-fallback:

call-forward busy 9577

call-forward noan 9577 timeout 10

Where 9577 is the operator DN.

How can I have all incoming calls forwarded to that DN?

Sounds like the default-destination command would work for you:

Although nowadays you're supposed to use the alias command as this works for incoming calls from PRIs etc that don't match an extension...

If it helps, rate it...

Thanks Aaron for the effort, but I tried both default-destination and the alias commands before but didn't work.

When I used the alias, I used .T as my "number-pattern" to match all pattern but no luck. The call stays off-hook with no action till it get disconnected.

You say the router answers, but the call doesn't do anything? Do you have ccm-manager fallback-mgcp in the config? For FXO ports, we usually do a 'connection PLAR OPX xxxx' to have it ring the right number, but if that phone is busy, you will have a problem - you can have the fallback call-forward busy and noan send it to another potentially available phone. If you have multiple lines and multiple phones, you can send each line to a different phone. Not as nice as one operator, but it is fallback...

Hi,

I think you are in 2-stage dialing with FXO which is not the same as PRI with DID as 1-stage dailing.

For FXO ports, when outside calls dial the main number, you will hear the dial tone, and then you can dial the internal extensions.

Thanks guys for your efforts and sorry for the late update because I was on vacation. I managed to solve the problem. As I mentioned in my first note, I'm using MGCP. In order for SRST to work in this case I needed to have following command:

ccm-manager fallback-mgcp

After I used this command, the router start forwarding the calls to the operator ext directly. Again thanks for all who send replies to my problem.
