Info
titleNote

SIP-I supports all of SIP-T. Because this protocol variant originated as "SIP-T", the original string is maintained in this record for legacy purposes. Otherwise all references to "SIP-T" are changed to "SIP-I" in this guide.

 

The following table lists all the sub-fields in the SIP Variant/SIP-I Signaling specific data field.

Example:

SIP-T,2203_1034102674@10.6.30.27:34975,<sip:9876543210@10.6.30.27:34975>;tag=1034102674,<sip:7661112222@10.13.1.35:4000>;tag=gK098024b6,0,ansi00,,,sip:7661112222@10.13.1.35:4000,user1@sonusnet.com,aliceinthewonderland,9876543210,sip:9876543210@10.6.30.27:34975,sip:7661112222@10.13.1.35:4000,msnr,9876543212,,1,,,0,0,,3,3,1,3cbed620-0001-1000-00-0000-10-6b-00-02-20,10.10.10.10,home1.net,dest.net,01793601014,123.14.15.16,0,0
