1. CgPN = calling party number.
2. GN = generic number (Q1912.5/EN 383 001, ND 1017 only). 3. GA = generic address (T1.679 only).
4. PN = presentation number (ND1017 only).
5. For SIP-URI in the P-Asserted-Identity or the From header field, if the field userinfo is E164 number with parameter “user=phone” or the field userinfo is E164 number with respectSipUriUserParm value set to 0, the Cisco PGW 2200 Softswitch treats the SIP-URI as E164 format.

Mapping Details
Note Table 7 is not applicable for SIP to SIP B2BUA. This table is for SIP-I involved calls and SIP to EISUP calls.
Table 8 describes the mapping from the ISUP connected number parameter to the SIP P-Asserted-Identity header.
Note Cisco PGW 2200 Softswitch does not split the address signal into the format, CC + NDC + SN. You can manipulate the address signal (for example, adding CC, or removing CC) by means of dial plan.
Table 9 is a matrix of calling line identification (CLI) suppression values based upon the incoming PSTN signaling settings and the SIP property cgpnInclude. The property cgpnInclude determines whether the call setup message includes CLI or not.
Table 8 Mapping the ISUP Connected Number Parameter to the SIP P-Asserted-Identity Header
ISUP Connected

Header Value
NOA national (significant) number tel URI or SIP URI1
1. A tel URI or a SIP URI with “user=phone” is used according to operator policy.
CC (country code) is added to
connected address signals to construct an E.164 number in the URI. The number is prefixed with a plus sign.
international number Complete connected address signals are
mapped to construct an E.164 number in the URI. The number is prefixed with a plus sign.
address signals • If NOA value is national (significant) number, the format of address signals is NDC2+ SN3.
• If NOA value is
international number, the format of address signals is CC4 + NDC + SN.
2. NDC = national destination code 3. SN = subscriber number 4. CC = country code

5. A tel URI or a SIP URI with “user=phone” is used according to operator policy.
CC + NDC+ SN as an E.164 number in the URI. The number is prefixed with a plus sign.

Table 10 is a matrix of generic number (GN) suppression values based upon the incoming PSTN signaling settings and the SIP property cgpnInclude. The property cgpnInclude determines whether the call setup message includes GN or not.
Table 11 is a matrix of presentation number (PN) suppression values based upon the incoming PSTN signaling settings and the SIP property cgpnInclude. The property cgpnInclude determines whether the call setup message includes PN or not.
