Call Negotiation
Inbound Call
The following section uses SIP to demonstrate the interaction
between the third party stack in the application and the Bfv API for
negotiating RTP and T.38 for an inbound call.
Systems that will perform RTP can generate the CED tone and avoid
setting the RTP on the Bfv. If this is the case, applications can skip
calling BfvCallSWConnectIP(FullDuplex RTP) and
BfvTonePlayBeep() CED.
If both RTP and T.38 are done with the Bfv API, some ICMP errors
may appear as the port is switched from RTP to T.38. To avoid the
ICMP errors use unique ports for RTP and T.38.
