This document assumes the user has a working knowledge of the SBC, its WebUI and the SMM function. |

When adding a custom SIP header, the case of letters in the added header is not preserved. To restore the proper case, a second SMM entry, using the Raw Rule, is needed.

Create a Header Rule that adds the User-to-User header and populates it with the value stored in SG User Value 1. SG User Value 1 would have been populated using a different SMM rule at the ingress SG.

When the SBC creates the new header, the case of the letters is not preserved (all the upper-case letters are sent as lower-case). To re-establish the proper case, make a second entry in the SMM table - a Raw Rule. Set the regex input to the lower-case and the regex output to the desired case. The Raw Rule will restore the desired case.
