VOIP Tech Chat → [CallCentric] Changed SIP password, cannot authenticate now.

I've got a CallCentric account that I've had for a couple of years now I think. About 3 weeks ago I set up a new VPS running Asterisk 1.8 with the help of a friend. Everything was gravy and working good. However, my SIP password was pretty short (8 characters/digits long) and I decided to change the password to be a bit more complex to keep hackers/brute forcers at bay (as well as other security changes like changing default context to something non-existent, alwaysauthreject=yes, running Asterisk as non-root user...).

I logged into my CC account and changed the SIP/Phone password (not the Web password mind you) to one that is 16 characters/digits log. I read their guide on passwords and followed it (they don't mention maximum password length though) by using a mixed case letter and number password, randomly generated. I then changed the sip.conf entries to the new password (where it says register -> number:blahblahblahblah@callcentric.com and also secret=blahblahblahblah). And restarted Asterisk to be safe.

After changing the password, I cannot get Asterisk to authenticate. I've tried shutting down Asterisk for up to 20 minutes then starting it back up. Rebooted the VPS, no help.

I've got a support ticket in with them but its been 12 hours+ without any response.

Am I missing something here?

Did you change the password in Asterisk in both the "PEER Details" and the "Registration String?"

Sometimes people forget and only change one. They're both on the trunk configuration page.

If that isn't it, try changing back to the original password, both on Asterisk and Callcentric and see if that works.

I would recommend you try and login using a softphone. That will ensure that the password is correct and that it must be a configuration issue with asterisk.

Okay I changed the password back to the original 8 character/number password (I thought I had tried that...) and it works. So CallCentric has a maximum password length that isn't documented in the change password field. Should have left it alone. Thanks for the help guys.

I've experienced the same problem with Callcentric. And I don't remember seeing any error in the portal when I changed the password.

I'm not sure if it just takes multiple tries or if there is something about the format/length that it doesn't like, but I suspect it's the length.

I ended up with a 15 character password that is working.

You might want to edit the subject line on your original post to reflect that this issue is solved.

Maximum password length is 15 characters.
