Using Third Party IP Stacks

#Specify an IP mask such as 255.255.255.0 ip_netmask=0.0.0.0

#Specify an IP address such as 192.168.0.1 ip_gateway=0.0.0.0 ip_broadcast=0.0.0.0 ethernet_speed=auto ip_arp_timeout=10

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.
