May i connect a sip trunk from telnyx or another provider with TLC protocol?

Hey Toketo1, we don't support TLC protocol.

/**
   * This is the protocol to use for SIP signaling outbound calls. Default is udp.
   *
   * @default udp
   */
  @IsOptional()
  @IsString()
  @IsIn(['tls/srtp', 'tcp', 'tls', 'udp'])
  outboundProtocol?: string;
