sip-hass-card SIP clients do not connect to Asterisk Add-on

[satnerd]

I have two sip clients configured. Details attached: sip-hass-card-config-yaml.txt.txt

The clients do not connect to the Asterix addon.
I cannot see a connection when checking with pjsip list endpoints.

I successfully connected SIP clients to Asterix addon using various SIP User Agents.

I then checked for java script errors in the browser console and found: console-errors.txt

It seems like the java-script variable this.config.prefix is not defined in webpack://ha-sip/src/sipjs-card.ts:715

I have no idea where such prefix needs to be defined.

I found the problem: The entry prefix: "" was missing in sip-hass-card.
I did a lot of playing and changing in this config file.
Is there a way to start from zero with all the endpoints in asterisk?
The ones in asterisk are not the same as specified in sip-hass-card
