Thanks QBZappy. Ping tests and all this is new territory for me, but I'm trying really hard to learn this. Today, I did a factory reboot of the Obi to clear out the Obi Wizard settings, and manually set my providers Callcentric on SP1 and GV SP2 in the expert configuration. It all works (which is impressive to me, and is an accomplishment in itself). Now, I can manually change security settings such as the SIP access.
This is the result of my ping test to Callcentric:
My computer timed out 4 requests (4 packets) (100 percent timed out), and returned one IP. I tried it twice, and got the same result each time. I did a Traceroute, and it timed out after step 9 (of 30 steps). My computer is old and needs to be updated, and it's slow--that may be the problem.
The Callcentric website says this under FAQ-Setup:
QuoteWhat IP blocks should I add to my router/firewall?
If you have a secured/restricted network and need to know the ports and IP addresses to allow for Callcentric then please use the information below.
NOTE: In general ports 5060-5080 should be allowed in order to properly communcate with the Callcentric servers. Users experiencing audio issues may want to check that RTP audio is not blocked by their firewall configuration:
IP addresses/Networks
204.11.192.0/22
OR
204.11.192.0 - 204.11.195.255
If you are making changes for security purposes or are using more adanced configurations please make sure that the ports used with your SIP UA are not blocked by your firewall rules.
See the large range of IP addresses: 204.11.192.0 - 204.11.195.255. Is it possible for me to put in that range of IP addresses (and how would I write that)? Also, the 9 IP addresses that QBZappy got--they won't be the same for me, correct (does it depend on my computer/location/router)? Would Callcentric be able to tell me what IP addresses to use for my computer/router? Also, if I don't use Callcentric's full range of IP addresses will I have problem making or receiving calls day to day when Callcentric routes calls through different IP addresses in their range?
When I ping
talk.google.om, I get
talk.l.google.com and a different IP than you got. The ping to google talk is successful, returning 100% packets and one IP address. I am having trouble understanding what you said not needing to white list this one--is it that SIP scanners don't or can't call into SP2 lines?
Thanks so much. SIP scanners having the ability to ring my phone and possibly hack into my accounts is unacceptable, and I will continue to learn to do this.
