5.2.2.4 Panasonic SIP Phones (P-SIP)DescriptionPanasonic SIP phones (P-SIP) have the following characteristics.• P-SIP phones use the activation keys for IP-PT/P-SIP (e.g., KX-NSM201) rather than the activation keysfor SIP extensions (e.g., KX-NSM701).• P-SIP phones offer the same features as general SIP phones.• P-SIP phones are registered and de-registered to/from the PBX in the same way as general SIP phones.Refer to the corresponding P-SIP manuals for the registration and deregistration procedures.Conditions• Requirement:A V-SIPEXT card is required to use a P-SIP phone.• A KX-TGP600 can be registered to up to 8 V-SIPEXT ports. In addition, one KX-TGP600 can support upto 8 wireless handset conversations simultaneously. However, since the number of wireless handsets iscontrolled by the KX-TGP600, from the PBX's perspective it appears that the number of occupied portsdoes not match the number of extensions (i.e., the PBX can only see the KX-TGP600 base unit).Depending on the registration status of the wireless handsets, up to 8 activation keys for IP-PT/P-SIP maybe required.• P-SIP phones are counted as general SIP phones and, therefore, are included in the maximum capacityfor general SIP phones.Installation Manual References4.4 Virtual CardsPC Programming Manual References9.15 PBX Configuration—[1-1] Configuration—Slot—Card Property—V-SIPEXT9.16 PBX Configuration—[1-1] Configuration—Slot—Port Property—V-SIPEXT496 Feature Guide5.2.2 SIP (Session Initiation Protocol) Extension
