Hi,
We have a CUE IVR that sometimes has to transfer to Lync server using a SIP dial peer.
When the call is going directly to the SIP dial-peer, the lync phone rings and we talk.
When the CUE IVR is involved the lync server refuses the connection with the error message:
SIP/2.0 488 Invalid incoming Gateway SDP: Gateway ParseSdpOffer Error: No DTMF support on Gateway side.
On the Lync side we can do nothing, On the Cisco side can we use sip-profiles to 'force' DTMF support in the SIP INVITE?
And if so what exactly should we use?
Has anyone an idea?
Thanks,
Jan
