to all fellow E71 enthusiasts: has anyone ever told you that they received an engage tone or got their call forwarded to voicemail when they tried to contact you, although your phone wasn't in use at that time and had full reception?
In other words: there has been a couple of occasions where I got an engage tone when I tried to call my own phone. It was weird, because my phone was just sitting idle next to me, with full bar reception!

After 2 - 3 attempts, then it finally rings. Worrying at the same time too, considering that I might have missed some important calls.
I'm using an ori avaxx set with maxis line, firmware 210.021.006, default settings everything, and no 3rdparty apps installed.
Anyone else experienced this? My previous phone was a Nokia 5210 using the same sim card, and had no such problems.
