To save me reinventing the wheel, has anyone done some work in their asterisk dialplan to 'clean up' the incoming callerid data from their SIP trunk?

I'm interested in things like:

64X[localnum] -> 4[localnum]
64X[nonlocalnum] -> 0X[nonlocalnum]
642X[mobile] -> 02X[mobile]

etc etc. That's not the exact set of course, just the concept. It looks easy to do with some variable tests and what not, but if someone else has done it already... :)

(on this note, what do people use for CIDName lookup if you use it at all? just astdb with LookupCIDName() and co?)

I use astdb with LookupCIDName().. Has great integration into FreePBX if you are using that.

Nup, apt-get install asterisk :)

Yeah, looking to just use astdb for now, may look into developing a simple web interface to a database table down the line.

More interested in the first item tbh :)

To start with I might just modify "64" to "0". I forgot to mention, that this is mainly so that redialing from callerid works on the old pots cordless.

I don't have any issues with my trunks - I'm assuming you're using iTalk or somebody that sends in the full IDD format?

I remember playing with this a long time ago and from memory had it strip the 64 and replace it with a 0 so last call return would work. I can't remember off the top of my head the code I changed but I remember Google being my friend at the time and it was very simple.

I'm not quite sure how you would differentiate between a local and non local number, ideally you should be using the 0x xxxxxxx for all local or national numbers so that calls outside your LICA that are also within the same STD code will work.

Yep, considered all of that... for now just 64 => 0 will be fine. (yes, it's iTalk, bite me :P)

I've come up with this:

[macro-process-callerid]
; Fix up the "64" prefix
exten => s,1,ExecIf($["${CALLERID(num):0:2}" == "64"]|Set|CALLERID(num)=0${CALLERID(num):2})
; Update the CallerID name from astdb
exten => s,n,Set(DBCIDName=${DB(cidname/${CALLERID(num)})})
exten => s,n,ExecIf($["${DBCIDName}" != ""]|Set|CALLERID(name)=${DBCIDName})
; Now Announce the callerID data to various locations on the LAN
exten => s,n,AGI(cid_dream.agi|${CALLERID(num)}|${CALLERID(name)})
exten => s,n,AGI(cid_growl.agi|${CALLERID(num)}|${CALLERID(name)})

Works well. The only downside is having to run away and add data to astdb :)

The other option is to "fix" the caller ID on the outgoing call. So an incoming call ID of:
6491234567 would be dialed from your pots phone as such, but your outgoing dial rule would strip & change 64 to 0.

That's true, but in this instance I want to fix up the incoming number, as it gets displayed on the TV and with growl on PC's on the network. Much easier to read without the 64.

Hi mjb,

Sorry to bring up an old topic but I just joined with iTalk.

When I get a missed call, I would like to view it, then press the dial button my phone and it will dial the correct number. However, given this format, when I try to dial it from my phone (using iTalk via Linksys PAP2T), it tries to dial "0649xxxxxxx" which then gives me an invalid tone reply....

Is there anyway I can fix this by putting in a dial plan or something into my Linksys PAP device?

Any help appreciated.

I have posted this on the iTalk forum at Slingshot but no one's reply so hence I thought I would ask here as I would probably get an answer here than on Slingshot's forum (

)

Thanks

looks to me that you already have a dialplan adding "0" to all numbers, so check that you have the country code and national code set in the dialplan? It seems to think that "64" is for national access.

Time to find a new industry!

You can't remap the CID from a Linksys ATA. Running something like Asterisk it's easy.

Your issue is that Telepermit specs say that phones have to add the 0 or 00 at the start of numbers, most phones allow this to be configured in the menu.

The real question however is why they are sending the CID in that format, while it's not wrong it's not user friendly.

I think they(in my case 2talk) do not send the caller ID like that, I think the issue is with the phone.
I have a Philips phone that adds 00 in front of the number all the other phones work fine.

Thanks techneister,

I agree. I tried my old Philips cordless phone and while it adds 00, I am able to dial the missed number fine. However, my Panasonic doesn't do it.

Think I'll have to get a new phone then to make it work with iTalk or 2Talk then.... :(
