Using Third Party IP Stacks

November 2009

263

The following section uses SIP to demonstrate the interaction 

between the third party stack in the application and Bfv for 

negotiating RTP and T.38 for an outbound call.  

Systems that will perform RTP can generate the CNG tone and 

avoid setting the RTP on the Bfv. If this is the case applications can 

skip calling BfvCallSwitchConnectIP(Listen RTP local IP/Port), 

BfvCallSWConnectIP(FullDuplex RTP), 

BfvLineCallProgressEnable() Generates CNG, and 

BfvLineCallProgressDisable. 

If RTP is also going to be done with the Bfv, make sure the port used 

in BfvCallSWConnectIP is unused. 

If both RTP and T.38 are done with Bfv, 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.
