I have had a few customers report seeing "asterisk" as the incoming CLID on some calls. I have also noticed this is who some voicemail-to-emails are "from".
Does anyone know why this might be or how to fix it?
Thanks!
Could you please elaborate a
Could you please elaborate a little more? We are running MTE, if that makes any difference. And I've also ported the installation on to a RHEL 6.1 server.
When you say "its not coming from you", what do you mean specifically? When they answer these calls, they are speaking with someone they know. Where is it coming from?
Thanks Erik.
Erik, I've managed to deduce
Erik,
I've managed to deduce that this is happening when our customers receive calls from callers without caller ID information.
Do you know where I can change this?
Thanks!
It's in sip.conf under the
It's in sip.conf under the general section. You should see a callerid=asterisk line if your server is generating that caller id.
Chris, Thank you for the
Chris,
Thank you for the response. My sip.conf file says "callerid=unknown" under the [general] context.
Any other ideas?
do a
there should be NO CASE where you receive a call from a telephone provider without callerid. If your provider is leaving off a callerid number off the calls, tell them to get their shit straight or 1) your are taking your business elsewhere. and 2) you are calling the FCC because they are forcing you to violate the CAELA requirements. How can you keep legally required call logs if you dont have the proper information.
callerid name is one thing.. callerid number... they are required by law to send that. get a sip capture and see if the data contains the calling callerid.
I think I've actually made
I think I've actually made some progress on this since my last post. Our inbound traffic is coming in on PRI to a G100 SIP/PRI gateway.
Any idea where this would happen in the G100?
in asterisk you need to wait
in asterisk you need to wait a second or 2 to collect callerid on the PRI because callerid comes in on the second frame of the call. look for a delay setting in your gateway to do the same
The gateway is already
The gateway is already configured to wait a second for caller ID (please see http://snag.gy/FmQhw.jpg)
I also want to be clear, that this appears to -ONLY- happen when people call from restricted numbers.
Should I try increasing that timer to 2 seconds?
that tells me 2 things.. 1)
that tells me 2 things..
1) your gateway device is probably running asterisk internally and thats why you see 'asterisk' in the CLID
2) it really should have passed it along as BLOCKED or restricted.. which is something that has to be coded on the gateway device or we could do it in thirdlane but not through the gui, would require a bit of custom code and changing the context in sip.conf for the device to send it to the custom code first.
one easy way to deal with it is to have the tenant refuse restricted calls by using call screening.. what kind of business blocks their damn number when making a business call? thats the kinda horseshit used by residential people that think its really blocking their number :-).. the other way to fix it is with custom programming like i mentioned
its not coming from you.. theyre being hacked.. pretty soon you will have a 10k dollar international calling bill. Thats what you get when you cut corners and decide that VLANs arent important.. you get your phones hacked.
