Hi Cullen,

Sessmatch does not make it any easier for an SBC in the signalling path to change the content of the MSRP messages. 

For an SBC to do MSRP message modification it will have to implement MSRP B2BUA functionality - no matter if sessmatch is supported by the endpionts or not.

Regards,

Christer
