First of all, sorry for cross-posting. I have spend a better part of today on calls with Airtel Customer Care, an Airtel Techie and an Airtel Customer Care Team Leader trying to figure out why a colleague could not make calls from his line. If he dialled any number, it would not go, with 'Check Operator Services' being displayed on the screen. More than 10 calls to Airtel and all I was being told is 'do a lock-up', 'we've refreshed the line', 'do a lock-up' and all this didn't solve Finally at 1620hrs, I call the number for Customer Care Team Leader and he asks me to check the SenderID setting under 'Call Settings' on the phone. I find that 'Send Caller ID' is set to disabled. He tells me to enable it and then try calling and voila! I am able to call. So I ask him why so and he tells me that on Airtel's network, if you hide Caller ID, you will NOT be able to make calls. I tested that option on my own phone and for sure I am not able to call, but at least it tells me 'Check Caller ID sending'... I tested that option on another phone with Safaricom SIM Card and I was able to make calls to Airtel, Safaricom, Landline... Someone please tell me what this is supposed to achieve, besides the fact that I believe this setting should be set at the pleasure of the phone user.When did CCK introduce this legislation and why is Safaricom (and probably other MNOs) not adhering to it?? IIRC, nowhere in my contract with Airtel did they mention that it's their discretion to decide on this option. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 "I can't hear you -- I'm using the scrambler."
