GSM Gateway => Outgoing Caller ID


#1

Hi Guys,

Has anyone any experience with GSM Gateways?
I’ve got one, setup and working quite well.

My problem is, and I don’t think there is anything anyone can do, is that when the call is made the caller id of the gsm gateway gets pushed to the remote party and not the originating caller id. I think this is just an unfortunate side of gsm gateways with no correction via asterisk.

I have seen some gsm gateways offer a feature called caller id regeneration which I suspect is capable of taking the originating caller id then regenerating it out on the call over gsm network. I could be wrong.

If anyone has a clue, let me know.

Cheers
Danny

I am not 100% sure, but as far as I know, the SIM card number (Caller ID for outgoing calls) is statically defined, so you can not change it. I think this is a GSM provider limitation. So your CallerID for outgoing calls that will go via GSM gateway will always be the GSM number that is set on the SIM card(or you can hide it on the GSM gateway :smiley: )

Hi,

Yeah that appears to be correct.
I might have to look into those dodgy china versions with caller id manipulation lol.

Thanks.

Hello,

I use 2n devices: Enterprise, Lite, and office route. They allow the Caller ID to pass through with CLIP options. You can turn it on and off actually. I’m not sure what GSM gateways you use, but this works rather well. The CLIP options are in the SIP line menu and under the LCR -> Route menu. I use these devices with both Asterisk and Cisco CME.

Cheers!

Hi,

I just have a couple of Ericson F250M and a portech device, none are really enterprise class and I haven’t had much dealing with them until now. The ericson works very well with asterisk with no configuration needed. I just configured it as a dahdi trunk and that was it. They are ideal for a small office. I was considering replacing them with newer models because many of the newer sims are now 3G and I thought I may run into computability problems, but so far the devices have accepted the 3G sims happily, albeit without 3G services available.

I will be sure to look at those devices you pointed out.
Thanks for the heads up.

Even though the 2n device is called Enterprise, it is far from enterprise. I think 2n realized this and renamed it to the officeroute. All the devices I mentioned above can only support 4 SIM cards. These devices cost between 1500-2000 USD. Overall these devices do what they say and I haven’t had a problem with them. The Czech translation can be a little off though in the manuals.

Okay thanks, I’ll be certain to take a look.

Hi all,

Did you find any gsm gateway that can manipulate the sim number?

Thanks

Bye,

The SIM number isn’t the same as the HLR directory number of the phone.

Any mechanism that allowed you to control the caller ID would be a bonus to fraudsters and phone spammers, so I hope no network would allow it to ordiary users.

caller id is defined. and it could be manipulated so it’s not the originating caller id.
