HMR to modify ISUP version in mime field

Hi,

for a SIP-I interconnection

I try to write an HMR allowing to modify the ISUP version mentionned in the mime  field

 

Content-Type: application/isup;version=itu-t92+;base=itu-t92+

and to replace it with:

 

Content-Type: application/isup;version=SPIROU;base=SPIROU.

 

I have tried the following HMR without success:

 

sip-manipulation name SIPM_ITU92_SPIROU_TEST

description

header-rules

      name tests

      header-name Content-Type

      action manipulate

      match-value

      msg-type any

      comparison-type pattern-rule

      new-value

      methods

       element-rules

       name mofigytospirou

       parameter-name application/isup

       type mime

       action find-replace-all

       match-val-type any

       comparison-type case-sensitive

       match-value Content-Type: application/isup;version=itu-t92+;base=itu-t92+

       new-value "Content-Type: application/isup;version=SPIROU;base=SPIROU"
