Calls connecting but no sound? - SOLUTION!

[Guest gs_london]

Hi everyone,

This is a post to save everyone 2 days of searching for a solution.

Yesterday morning my Vario II started playing up whilst making calls. The calls would connect but no sound was coming through or getting out of the device intermittently.

I'm with T-Mobile and couldn't even connect to log a fault because I couldn't ear anything on connection.

The device would connect sometimes but there was no pattern and very random.

I finished work and went home and made probably 200 odd calls driving everyone mad trying to fix the problem or at least see if it had gone away. It hadn't my phone was buggered (or so I thought)

I have spent 10 hours today researching the problem and there isn't anything I could find to even suggest it was a common fault with the phone.

2 hard resets and probably about 20 or so soft ones did not rectify the problem.

I was resigned to sending my device back to T-Mobile for repair but one last assault on finding the problem I stumbled on the solution.

The symptoms were the calls connected but no audio was present in both directions. On my handset I could hear a faint 3 second 'fizz' sound then stone silence.

I suspected it was the network but had no way of finding out. All other T-Mobile friends were not experiencing any problems so maybe I was wrong.

I started to read every hermes forum post looking for a clue, plugin, software mismatch - in fact anything call related and stumbled upon a post from jeremymacmull in discussion about audio dropping out from a call.

He said:-

"Try forcing your phone into GPRS 2G mode only its in the settings for phone. And then see if this still happens."

Bingo - followed his advice and set my network band selection to GSM instead of automatic and the problem was solved. It seems either my device has lost the ability to carry audio over 3G or T-Mobile are having 3G problems in North London where I live and work.

So if this ever happens to you remember until its fixed

Settings -> Phone -> Band "Select your network type" and set it to GSM (instead of Auto) then at least you can call T-Mobile and find out if there is a problem.

And many thanks to jeremymacmull

You my friend are an absolute star !

Lost your signal earlier on today then ? I'm in N5 and this has driven me nuts...... Remove programs, rebuilt. I reinstalled the T-Mobile .cab in the extended Rom last night and this fixed it. I thought that it was an issue with the Palm Messaging I installed last week.

I actual lost the ability to make calls a week or so back so it makes sense it is transmitter problems in the North London area.

THANK YOU AGAIN !!

Likewise, this started for me on Saturday afternoon, EN2 I'm in. Seems to still be the same, but I'm not chuffed. I had hard reset the device and everything, but for no reason i would seem! What a bizarre problem! Wonder when T-Mob will get it sorted? I'll phone tomorrow if it's not.

Cheers guys!

As you will see from various threads, 3G networks do suffer from reliability problems. All of the operators 3G nets fail in different local areas fairly frequently.

Users experience problems when the 3G net thinks its working (but has a fault) and thus the device doesn't auto switch to GSM.

Well, it's still down for me at the moment, but switching to 2G works well enough. I'm going to have my lunch and then give them a call. Was hoping it would have been sorted by now :-(

Happened to me twice yesterday in WC1, good to know how to solve it if it happens again.

I live in High Wycombe and have experienced exactly the same problem here and also in Watford. If this is a common issue then perhaps Paul (MVP) may be able to assist with a .cab file to allow easy manual switching between 2g/3g networks (in the same way that his excellent data off toggle cab works)?

Thanks for the solution :) - I'll try it next time and stop annoying my wife when I call her and she cannot hear me!

Has anyone experienced problems with making calls to specific numbers and not being able to be heard by the other person? This happened to me the other day when I called a company's switchboard (several times) - the other person couldn't hear me.

Course, I'm not ruling out that it was a technical fault at their end, but it's not the first time that people haven't been able to hear me when I've spoken (and a replacement is in the works, waiting for my local store to get new Vario 2s in!) but it was still very odd. Either side of this problematic number I was ringing other numbers fine on my phone and I could be heard ok, but I just thought I'd ask given the context of this thread.
