[Q] Really bad delay in voice calls in CM7.1 RC1

When my phone is locked, I simply just dont recieve calls. It rings on the other persons end, but it doesn't pop up, there's no ring tone playing on my phone, and there's no missed call indicator even. I just dont get the call. I get the voicemail afterwards at least.
When my screen is on I get the call immediately. However, there is a pretty bad delay either in incoming voice or outgoing. People respond 3 seconds after i finish talking and I'm constantly cutting them off. What's up?
I don't have any issues on the nightlies; maybe you should update to a more recent rom.
it's the latest release candidate - i've had it installed for like 2 days.

Dropped Calls / Out of Service Area

Appears to be a common problem on the device around the world.
Have 4.0.2 as stock.
If I talk to someone i sometimes hear noises similar to a fax line but just more garbled and scratchy followed by a clicking sound and the call is dropped.
Signal bars show no signal. If i try to call when this happens i get out of service area message. If i try to connect to data, i get airplane mode message. After a few seconds the bars return to full strength and i can call again.
I have not experienced the phone muting at all which most people are experiencing.
It happens less if i use 3G instead of 2G and as soon as the call is initiated i press the power button to dim the display.

[Q] Galaxy Nexus Signal Bars Go Grey, Can't Make Calls and Dialler Doesn't Exit

I'm running stock Android 4.2.2 JDQ39, baseband I9250XXXLJ1 on the GSM version of the phone.
I suspect this happens after the phone exits sleep mode. The signal bars go grey, and I can't make or receive any calls.
People calling me say that they can hear the ring, but my phone doesn't receive the call.
When I try to make outgoing calls, there is no response and when I try to hang up, the dialler doesn't exit.

Voice Calls sometimes get garbled and distorted?

Even when I have full signal and LTE I'll sometimes hear the other people on the line sound so garbled fading in and out that I miss a couple words here and there. Anyone else ever experience this intermittently? I've had it happen four times the past two days
yes im having that problem too every time i receive a call, they say i sound like robot, but when i call back is not, i disable wifi calling but not solve that

[Q] No Call sound / Out of service area

Can anyone help, i upgraded to 4,3 and can no longer hear any audio in a phone call, either way, the speaker and mic are fine,
I have restored to stock 4.1.2, with the same issue, have flashed a number of modems but still have the same issue,
my imei is correct and i can make calls receive texts etc, so the phone is not blocked,
sometimes the call disconnects abruptly and i receive a 'out of service area' message and lose all reception until it restores a second later,
i have been searching for a solution, but have so far not found one, i have tried sound about, lock screen sound etc
i know this was an issue on the nexus 4, does anyone else with a note 2 have this issue???
