It seems that the n900 doesn't display a 2nd incoming call while it's displaying a first one. This is particularly a problem because my VoIP phone number also rings (deliberately) on my GSM phone number.
Now I realize that it's technically possible to recieve the GSM call over the cell network, but if I'm not on WiFi, I'd rather not bother --- my cell plan is sufficient for when I use it.
... so how do I solve this? I'd like to either a) not have sip ring at all when not on WiFi, or b) have both calls presented to me and the option to choose which to answer.
