For some reason whenever I try to use the dial key to call a missed call, it returns to the main screen as sip:__________.
I'm not sure what the problem is. If I edit the number while under the missed call list, I can delete the sip: part and then it will dial out fine.
I thought that perhaps it was trying to dial the number as sip:1234567890 instead of as 1234567890 so added a Rsip:RRxxxxxxxxxx to the digitmap, but that hasn't worked either.
If anyone has any ideas or knows how to fix it, that'd be great. It has software 22.214.171.12406.
Found the answer:
Turn off URL-Dialing (feature.urlDialing.enabled="0")
