I have noticed that when using the sip that he as built in (Touch Input as its called on the phone) that the lag was quite apparent on the manila mms screens. I found it worked better while the volume was silent.

That led me to play around with the registry, and got it to work with almost NO hangups. I am using the august release I believe (any way to check???) but found the hang ups were almost non existant once I changed the registry value to not play any noise while keys were being typed.

registry\HKLM\software\HTC\ezsip\clicksoundenabled <-- change value from 1 to 0 as well as the value for vibrationenabled from 1 to 0.

This worked for me, and may help others.
