Delayed DTMF code for Door Relay

[Stewart1 (Stewart)]

Since this is an outbound-only trunk, the only difference is whether the calling extension number or its Outbound CID gets sent to the Snom (and CDRs). I assume you would want the extension number, so choose intra-company.

This should not require any custom dial plan or other complexity. I don’t have a Snom but just tested the below with an ATA, hearing the DTMF played at the destination:

1. Create a Custom Trunk with Custom Dial String set to PJSIP/35999 and Asterisk Trunk Dial Options set to D(www3#)
2. Create an Outbound Route with match pattern set to *0911, pointing at the above trunk.
3. If your Speed Dial Prefix is set to the default *0, you must disable it, change the code, or use something other than *0911 for the trigger.
4. Test. If the Snom answers but the DTMF is not sent, try forcing DTMF in-band audio for the extension.

If you still have trouble, paste a log, including SIP trace and DTMF.

This is the solution! Not saying the other methods wouldn’t have worked and I appreciate everyone that contributed. Thank you, @Stewart1!
