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.
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.
