Cyta SIP trunk integration

Hello, we need to connect VAPI to the main local telco provider in Cyprus - Cyta.

We managed to register a SIP, but then encountered issues with outbound calls.
  • Cyta receives invites if outboundLeadingPlusEnabled=false. But they can process calls only with a plus or 00.
  • If outboundLeadingPlusEnabled=true then Cyta doesn't receive invites.
Please advise who can review the logs provided by Cyta and guide us on how to adjust the settings in VAPI to enable outbound calls using the leading plus (+).
