SIP Interop Tweaks

A value too low increases the network load.

Affects handling of "484 Address Incomplete"
responses. If enabled and "484 Address Incomplete" is
received, the call is cleared. If not enabled and "484
Address Incomplete" is received, the call is retained
and re-initiated in case of new dialing digits.
• From Header when
Sending INVITE
Interoperability option for outgoing calls. This controls
the way CGPN is transmitted to the SIP provider.
Possible values are:
- Fixed AOR - The From header contains the fixed
registration URI (AOR). The actual calling party number
and name will be transmitted inside the P-Preferred-
Identity header (RFC 3325).
- AOR with CGPN as display - The From header
contains the fixed registration URI (AOR) with the
calling party number as display string in front of the
AOR.
- CGPN is user part of URI - The From header contains
an URI with the calling party number as user part (left
from @).
