Per RFC3262 it is 100rel not 100REL.

Hello to everybody...

Kindly help me with the difference between "100 REL" and "100 rel".

We have a ZTE ZXSS SS1a/b soft switch and a SIP trunk interconnection
with a Nortel CS1000 PBX. On the SUPPORTED header of the Invite from
ZTE, it places "100 REL". On the other hand, the supported header from
the Nortel CS1000 indicates a "100 rel". IS there a chance that the ZTE
soft switch does not accept the "100 rel" from the Nortel PBX?

Kind Regards,

Chesser Domingo
