I have tried changing the framerate by modifying the value of qcifMPI in H245Capabilities, but the framerate still couldn't be reduced from ~10FPS (Nokia C5) so I think it is like what you mentioned that the phones does not honor the parameter. There is no way to set the framerate on the phones I have seen so far.<br>

The quality of the video is dependent on the rate control algorithm and in the 3g TDM world with 64 kbps total BW available, you cannot expect super quality. One thing you probably can do is reduce the framerate,so that the more bits are allocated to a frame and better quality is produced. But I am not sure whether phones honor the framerate parameter during signaling. You can try, or try if you can set the framerate using the 3g phone settings.<br>

<div>I am using mp4save to record directly from a 3G phone. I thought H245 negotiation would always be required regardless of whether phone-to-phone or phone-to-asterisk. Please enlighten me on how to establish video calls without involving H245 nego in the case of phone-to-asterisk.</div>
<div> </div>
<div>Anyway, if both phones are same model, I think the quality might be better since both would has same H245 capabilities. Unfortunately I do not have a pair of same-model 3G phones to do such testing here. From my experience, even for phone-to-phone video calls using phones of same brand(Nokia N73 + Nokia C5), the quality is pretty bad too.</div>

<p>Why should phone 2 phone quality suffer while recording? This shouldn't require any transcoding.</p>

If It's direct record, as Dan suggested, it depends on the encoding capabilities of each phone. If the encoding is hardware based, you can't do much. One other thing I've found is that whe I do phone to phone video calls, quality is great, but if you do the H.245 negotiation and try to record to your device, then quality suffers.<br>
