[Serusers] Possible bug in SER or Cisco GW?

Hi all, I'm observing a very strange behaviour....when I'm calling from PSTN through Cisco GW to my SER Proxy, if in my voip dial-peer there's the CLI command 'dtmf-relay rtp-nte', and then in the SDP line appears this 'a' line 'a=fmtp:101 0-16', when arrives to my SER, SER itself is unable to process it...below the ngrep dump, where the actors are: A.B.C.D: SER IP addr E.F.G.H: GW Cisco SIP signalling addr E.F.G.K: GW Cisco SIP media addr W.W.W.W: my SIP ATA addr U E.F.G.H:52007 -> A.B.C.D:5060 INVITE sip:0662293701@sip.mydomain.org:5060 SIP/2.0.
