Trunk Link to Draytek Vigor IP PBX2820

I have been setting up a trunk link to dial extensions on a Dreytek Vigor IP PBX2820.

Calls from the IP PBX2820 are working fine from a trunk on the IP PBX2820 to my FPBX 15.0

Calls from the FPBX 15.0 back to the IP PBX2820 are also fine so long as the extension answers.

However if the call is not answered the the IP PBX2820 sends a request for the FPBX 13.0 to forward the call to the “vmpbx” with the following showing in the logs.

Now forwarding PJSIP/207-00000358 to ‘Local/[email protected]

My guess is that my FPBX 13.0 is rejecting that request as “vmpbx” doesn’t match a call pattern for the trunk.

If the request was a transfer to say “8500” instead of “vmpbx” then I would add “8500” to the outbound call pattern and the transfer would be completed but I can’t see a way to complete this when the request is “vmpbx”.

Would anyone have any thoughts on how I might resolve this and get “vmpbx” request sent through the trunk?

You can fix this with a bit of custom dialplan:

[from-pstn-custom]
exten => vmpbx,1,Noop(Entering user defined context from-pstn-custom in extensions_custom.conf)
exten => vmpbx,n,Hangup   ; modify to send call to wherever you want

General advice is to never (ever!) use the context from-pstn-custom, but this is one use case where it would be acceptable. You need to figure out what to do with these calls and modify the second line to suit. Note that the forwarding address is context from-pstn, so the FreePBX system is treating this forwarded call as and INBOUND call, meaning it will follow an inbound route. If you’re not careful, you could easily create an infinite loop here.

Thanks for the advice much appreciated.

Your custom dial I understand, I just need to modify “Hangup” on the second to whatever I want the action on my PBX to be.

I have looked at the logs when I make a call and can see a call [9281] from my extension (207 FPBX) to remote extension (175 PBX2820) and I understand it to the point where 175 is ringing and then times out the PBX2820 wants to transfer to Voice Mail [9282] and then on to line [9283] where the call is not accepted. At this point I have to admit I am a little confused, I thought that was my PBX refusing the call because it had no route although now I am wondering if its the remote PBX refusing the call?

How do I understand from the call log what action I need to insert into the customer dial plan to prevent the call failing and make it go through?

Any help you can offer as ever much appreciated.

The dialplan provided above is Asterisk diaplan, so any resource explaining Asterisk will point you in the right direction. Or you can describe what you want to happen and we can try to assist.

Thanks for your help and advice again. Did some testing and some googling and came to understand from your previous advice

[from-pstn-custom]
exten => vmpbx,1,Noop(Entering user defined context from-pstn-custom in extensions_custom.conf)
exten => vmpbx,n,Hangup ; modify to send call to wherever you want

that if I added an entry like this

[from-pstn-custom]
exten => vmpbx,1,Noop(Entering user defined context from-pstn-custom in extensions_custom.conf)
exten => vmpbx,n,Dial([SIP/[email protected]:5070,50,tr]

When I got the failure my PBX dialled back but the caller was presented (from the IP PBX2820) with an offer to select an extension to call, this then called the extension and also allowed voice mail to work.

So I worked towards a solution of

FPBX user calls PBX2820 extension (170) number, >
FPBX calls [[email protected]:5070] >
Call establishes, >
Call pauses, >
FPBX sends request for called extension (170) and then >
PBX2820 processes the call to the extension and voice mail as required.

Removing the FPBX Outbound Rules and just using this I was working on something like this

[from-pstn-custom]
exten => 170,1,Noop(Entering user defined context from-pstn-custom in extensions_custom.conf)
exten => 170,n,Dial([SIP/[email protected]:5070,50,tr]
exten => 170,n,wait(3)
exten => 170,n,SendDTMF(170)

With a possible modification to include a range of 17X extensions on the remote PBX
and a variable to the SendDTMF(17?)to reflect the extension selected but couldn’t
seem to get it go through. However while trying to research SendDTMF function I came across
this simple solution`

exten => n,Dial (SIP/97,60,D(ww1234))

So I went with this entry and got a result.

[fom-internal-custom]
exten => 170,1,Dial(SIP/[email protected]:5070,50,D(ww170))

to cover the range of extensions (10) on the PBX2820 I just added additional lines

[from-internal-custom]
exten => 170,1,Dial(SIP/[email protected]:5070,50,D(ww170))
exten => 171,1,Dial(SIP/[email protected]:5070,50,D(ww171))
exten => 172,1,Dial(SIP/[email protected]:5070,50,D(ww172))

So with a bit of luck, some google research and your much appreciated advice I
have a working solution. I am sure there is a more eloquent way to write this, but for
me this is fine.

Again, thanks for your help.

Can be done with a single line.

[from-internal-custom]
exten => _17X,1,Dial(SIP/[email protected]:5070,50,D(ww${EXTEN}))

I knew there would be, my inexperience certainly shows. Again thanks for your help (and patience).

Just out of interest, is there a way to limit the information in {EXTEN} so that a user could dial 9170 but only pass the 170 to the external PBX?

[from-internal-custom]
exten => _917X,1,Dial(SIP/[email protected]:5070,50,D(ww${EXTEN:1}))

Your are clever, I have much to learn !! Thanks for that.
