Configuration of Lines: SIP Lines

As of LCOS 10.94, it is possible to enter a phone number in the Account-Number field of the SIP Lines table (Voice-Call-Manager > Lines > SIP Lines > Advanced) that belongs to this SIP connection.





Account number
Enter here a phone number that belongs to this SIP connection. For SIP lines of the type "Flex", this source number is transmitted in the PPI for account verification. If the FROM number is modified by call routing or if the SIP phone sends a number that does not match the connection, this will not cause the call to be rejected by the provider. This allows CLIP no screening calls to be made directly via the VCM, provided the feature is supported by the SIP provider.
