Configure a SPA9000 AA entry to leave Voicemail

Unanswered Question

We need to transfer a call from AA directly into a specific voicemail box.  I have read Alberto's document on how to accomplish this but we have been unsuccessful so far (see my detailed comment on that document).  Our configuration is SPA9000 + SPA400 + SPA962.  We are currently only using the PSTN via the SPA400 (no ITSP yet).

One of the steps in that document involves setting up a hunt group "shortcut" to a specific voicemail box.  When used alone, this will allow a caller on one of our internal SPA962s to transfer a call into voicemail, and will even allow AA to transfer the call to a specific box but ONLY when AA is called from inside (we do that for testing).  External callers are not able to get the transfer to work.

So we were excited to see Alberto's document but cannot get it to work they way he suggests, even for calls being directed from the inside.  Using the xxxx<:@> dial plan substitution does not seem to get the call to the hunt group.

I am trying to understand what that destination means, as well.  What is at port 5083 on the local unit?  I guess the crucial question is why doesn't the VMxxxx destination work for calls that were originated from the SPA400 and are being "managed" by them (remember that I am pretty sure I can forward a call from the outside to a huntgroup from an internal phone).

Thanks for your help.

Could you please send me the SPA9000 configuration? It should work properly from SPA400.


PS: How to get the SPA9000 config?

Hey Alberto!   Were you able to see anything in my configuration that would prevent the transfer to voicemail from working?  Thanks for your help.

Hi Mark;

Yes (sorry for the delay, have been on PTO).

- On the [SIP] AA Dial plan you have an error. Instead of   xxxx<:@> , you need to enter xxxx<:@>. This is basically forwarding the call to the vm relay port.

- On the [SIP] Hunt Group definition, you need to include the entries (as hunt groups) you want to forward to email, i.e. 3102:cfwd=vm2102|3100:cfwd=vm2100 (if the extension numbers are 100 and 102 respectively and you indicate the user to prefix 3 to leave a voicemail).

- Set [Line 1] VMSP bridge to All (you have it All+self).

Please make the change and retest.

I had problem with AA to voicemail too. Apparently i can get in to AA prompt but when i dial eg 3101 on the softkey button, I heard AA voice " your call has been forwarded", then it goes to busy tone. Not sure about this syntax (xxxx<:@>), is that mean should be replace with SPA400 ip address ?? Here's my current setup

1 x SPA9000 :

1 x SPA400 :

1 x SPA962 : 192.168.1.x

Hunt Groups: 3101:cfwd=vm2101

AA Dial Plan 1: (xxxx<:@>)

AA script 1:


Contact List: 101,cfwd=aa

Please find attachment thanks

Hi Kenny,

If you dial 3101 from an IP phone, what phones ring?

Scanning over your config file, it's difficult to analyze because the SPA9000 appears to have just been rebooted, Info page shows uptime of 0.

It looks like the 3101 hunt group may not be properly defined. Normally the hunt group is defined in SPA9000 web-ui > SIP tab > PBX Parameters > Hunt Groups:

or in the SPA9000 web-ui > Line N tab > Subscriber Information > Contact List:

Here's a link to the Admin Guide which describes hunt group syntax if you choose not to use the Wizard:

Consider using the Wizard to configure the SPA9000 and related devices and then making specific changes using the web-ui. This way, hunt group syntax etc. will all be correct.
