Asterisk 1.8 Google Talk Inbound Caller ID (CallerID)

If you need to send the proper calling party’s caller ID to a phone when using GoogleTalk, follow the below dialplan. Without any setting, the caller number is set to UNKNOWN and only the CALLERID(name) field is sent with something like sanjayws@gmail.com/Talk.v10471914EB6E. So we tweak the dialplan to show the correct caller ID. Put this dialplan anywhere in your Google incoming dialplan and you should see the calling party just nicely.

exten => stunningsimplicity@gmail.com,n,Set(Thiscallchan=${CALLERID(name)})

exten => stunningsimplicity@gmail.com,n,Set(CALLERID(name)=${CUT(Thiscallchan,/,1)})

exten => stunningsimplicity@gmail.com,n,Set(CALLERID(num)=${CUT(CALLERID(name),@,1)})

Here’s what you will see

**Assuming here, that your diaplan starts with the email address like in a post i did previously below, otherwise, change that accordingly, or change stunningsimplicity to any incoming GoogleVoice email that is expected to land on asterisk.

We remove @gmail.com as it will not quite work with your phones as it will try to do a SIP/IAX @ gmail call.

It’s best to prefix some characters for gmail outbound calling, and in my sample configuration below, i do a g* followed by a google name to dial as we add @gmail in our outbound dialplan. So you can add for incoming a g* automatically like below

exten => stunningsimplicity@gmail.com,n,Set(CALLERID(num)=g*${CUT(CALLERID(name),@,1)})

And so because we add a g* the CallerID(num) field will change to g*sanjayws (where sanjayws is the calling party from an original string received like sanjayws@gmail.com/Talk.v10471914EB6E). Now a person receiving the call can simply redial.
