T- Mobile Pulse/Pulse mini Calling Issue

[Guest LambOfGod]

hi all, im not sure if its the low hardware spec causing this to happen,

but from time to time, when someone tries calling(about 2x a week this problem occurs):

• only rings for 2 out of 10 rings
  
• for the last 2 rings phone hangs while trying to answer
  
• once answered, call displays as missed
  
• OR
  
• someone rings until my voicemail, I wont recieve any call
  
• still recieve missed call
  
• OR
  
• no missed call at all
  
• (more of an issue with pulse mini)
  

Pulse - 2.2 CM6

mini - 2.1 FZF

Both on T-mobile UK

anyone else having/had this issue?

hardware/software issue?

and is it possible its a network issue?

cheers
