VoIP Phones - UDM-Pro
UDM Pro with Unifi Talk
One of our clever customers Rob managed to get this working by editing a .js file.
First enter the VoIP/SIP credentials as per image below. The UDM will set the sip_from_uri = sip:+44123456789@talk.com which needs to be corrected.
Then edit the file: /usr/share/unifi-talk/app/server.js
And replace the 2 references or sip_from_uri like this:
{application:"export",data:"sip_from_uri=sip:${outbound_caller_id}@talk.com"}
With this:
{application:"export",data:"sip_from_uri=sip:${outbound_caller_id}@voiceless.aa.net.uk"}
Not an ideal solution as will need to make changes to the file whenever I upgrade but it appears to be working.
