Dialling a Dynamic extension number from value captured and processed from DTMF

sahmed84 · February 7, 2023, 2:02am

Hello

Sorry if this has been already answered but I could not find something similar to my issue by searching here.

I am trying to create a call flow where:

The inbound call is sent to a Dynamic Route
6 Digit DTMF is captured (Sales Quotation Number) in a variable named: DYNROUTE_quote_id and matched against an API which returns an extension number of the agent who is dealing with the quotation.
The Result is saved into a variable in Dynamic Route Saved variable section named: DYNROUTE_agent_ext
Then the call is sent to a Custom destination with target: from-internal,${DYNROUTE_agent_ext},1

However this is failing with the following output:

== Using SIP RTP Audio TOS bits 184
== Using SIP RTP Audio TOS bits 184 in TCLASS field.
== Using SIP RTP Audio CoS mark 5

Looks like for some reason the variable is putting a null value to the dialplan. I will be very grateful if someone could kindly point me to the right direction to achieve this. Many thanks in Advance.

The agent_ext seems to also be “500001”. Is that a valid extension?

sahmed84 · February 7, 2023, 11:43am

Hi yes. 500001 is a virtual extension with Voicemail enabled for test.

sahmed84 · February 7, 2023, 12:12pm

Hello, I think I have figured it out. I kind of misunderstood the tooltip:

“This is available as [xxx] in the query/lookup where xxx is the name of the variable you specify here. To use the variable in the dialplan (e.g. custom applicaitons) it is necessary to prefix it with DYNROUTE_ e.g. DYNROUTE_xxx”

I have now renamed the result variable to: agent_ext (previously was DYNROUTE_agent_ext)

and in the custom destination set the target as: ext-local,${DYNROUTE_agent_ext},1

Seems to be working!!!

Good stuff. There is a method in this post where you can use a second Dynroute to validate that the API returns a valid extension number: Dynamic Routes - Extension Check - #2 by lgaetz

${DIALPLAN_EXISTS(ext-local,${DYNROUTE_agent_ext},1)}

The second dynroute could then branch call to the extension or to a generic destination.

Thank you kind Sir!
