I had my CLS 55 installed with the Cingular Wireless version of the Motorola v600 phone, as modified for Mercedes-Benz to work with the VCS (i.e., handsfree).

This phone has been plagued with problems that have been increasingly noticeable and annoying, but none more so than the fact that Call Waiting does not function. When I am on the phone and another call is made to my number, either I see the call appear on my screen (but I cannot flip over to it) or the call goes directly into voice mail.

Today, my dealer replaced the phone, but the Call Waiting feature still did not function. Accordingly, I called Cingular Wireless customer support and, after nearly an hour of fruitless interaction, I was finally transferred to that carrier's technical support personnel.

I was told by the Cingular Wireless tech support person that Motorola has now recalled the v600, but that no replacement for it has yet been announced.

Is anyone else who has a v600 phone also experiencing this problem with Call Waiting? If so, what have you done to rectify it, or are you just living with it?

I have the V600 from Mercedes Benz in my E55 and E350. I just take the phone with me. It seems to work fine. Perhaps you need to get a Mercedes Benz V600 that is unlocked and has the correct firmware.

I have had the phone for 6 weeks and has worked perfectly. My carrier is Verizon. My friend who sell phones says he did not know it to be a problem.
So many functions on the phones now... a lot of reading and reviewing needed.

Persons who use Verizon have the v710 phone by Motorola. Only those who have Cingular Wireless as their service provider have the v600.

This evening, Cingular Wireless' technical support called my home. This "problem of mine" intrigues them to the point that we are going to run a test tomorrow at 11:00 a.m. employing multiple Cingular Wireless handsets and call waiting trials on the network. So, we shall see.

Regardless, I don't understand why problems like this arise with a car like the CLS 55.

It will be interesting to see where the fault lies.
Glad I have Verizon

were they able to resolve your phone issues?

clarification question: call waiting does not work when you are holding the phone in your hand, or when you have it linked to the car?

i have the phone and it works fine holding it (no issues).

in the car, the secret is to hit the green SEND button to switch over to the other call. give it a shot.

My good fortune was a clever techie at Cingular Wireless who gave me the insight to discover that the problem was neither the V600 phone nor Cingular Wireless.

The culprit in this case was a defective SIM card! By putting my defective SIM card in any advanced Motorola phone, I was able to get that phone to malfunction; more importantly, with another SIM card in my phone, my phone worked as it was supposed to work.

And so, I got a new SIM card from Cingular Wireless, and, Voila! I am once again a happy camper.

Now, if I could just get Cingular to lower my $900 of international roaming charges last month...

unlock your phone, and use local sim companies when you are abroad. no international roaming.

as for customers, give them a phone number that you can forward remotely. when you are in the us, it goes to your us cell phone. when you are abroad, you configure it to go to your international #. no roaming and your customers see one number.

congrats on solving your issue. for me, they forgot to software rev the antenna amplifier so i was getting no signal. after 2 weeks they figured it out.

How much are the dealers charging for the phones that go into the MB phone system?
