asterisk users - Dec 2005 - polycom sip slower than grandstream

I have a polycom 501, for some reason asterisk always shows the round
trip time to it as being significantly higher than the 2 grandstreams,
all 3 are on the same lan.

 

 

 

Grandstream 40/40            192.168.16.40    D          255.255.255.255
5060     OK (4 ms)

Grandstream 31/31            192.168.16.31    D          255.255.255.255
5060     OK (4 ms)

Polycom       30/30            192.168.16.30    D
255.255.255.255  5060     OK (78 ms)

 

 

 

Any thoughts?

Its all in the priority the phones assign responding to messages.  
Sipura are also fast compared to Polycom.

this is not an accurate measure of network latency.
