Removing T38 from SDP

Dear team,

I need to add  element-rules in order to remove all attributes related to T38 codec.

For example :

a=T38FaxVersion:2

a=T38MaxBitRate:14400

But also the " image udptl t38 "

I am using the following but it does not work:

element-rule

                                                name                           strT38

                                                parameter-name                 application/sdp

                                                type                           mime

                                                action                         find-replace-all

                                                match-val-type                 any

                                                comparison-type                case-insensitive

                                                match-value                    a=T38.*

                                                new-value                    

element-rule

                                                name                           striT38

                                                parameter-name                 application/sdp

                                                type                           mime

                                                action                         find-replace-all

                                                match-val-type                 any

                                                comparison-type                case-insensitive

                                                match-value                    m=image.*t38.*

                                                new-value                    

Attached you may find the whole HMR. Everything else except of T38, work properly.

Thank you in advance,

Kostas
