Comment (by [EMAIL PROTECTED]):
I found a 'best' practices white paper from Spectralink will had the
following excerpt...
{{{
2.3.2 Push-to-Talk
Multicasting
Considerations
The push-to-talk (PTT) mode of the NetLink i640 Wireless Telephone
uses SpectraLink's proprietary SpectraLink Radio Protocol (SRP)
ADPCM encoding. If a PTT broadcast is active (i.e. a user presses the
PTT button), the feature will use the bandwidth as indicated in the table
above for the single transmitting i640 Wireless Telephone and one half of
the bandwidth for all of the receiving i640 Wireless Telephones. The data
rate used for PTT depends on the AP's settings for multicast traffic. This
bandwidth used is independent of the number of handsets receiving the
PTT call. Because the PTT mode uses IP multicasting, all APs on the
subnet will transmit a PTT broadcast unless the network is running
Internet Group Management Protocol (IGMP), in which case the
broadcast will only go to those APs that are associated with NetLink i640
Wireless Telephones with the PTT feature enabled.
