Hi Kev,
I haven't progressed on that question yet, but I suspect it may have been resolved by forcing a re-register in the 3CX Line settings page after re-enabling the RTP rule.
I guess like many, I'm rushing on to the next problem to solve once something starts working!
New challenge: Getting the 3CX softphone to accept incoming calls. I think this is another firewall issue.
Scenario:
I have several staff who are peripatetic (move around th country).
I want to allow SIP to SIP calls between them and our head office.
Sometimes they will be at Head Office.
My solution:
So, I have approached this by creating a new extension on my 3CX.
I also create an external SIP account, in this case using Sipgate si I'm using the same provider as for my 3CX sip account.
For the 3CX extension, set up call forwarding with the outgoing dial rule set to use our 3CX SIP account (simply a * prefix to the number), directed at the new Sip account.
Testing and results:
Using 3CX softphone, I can login to the new Sip account. (OK)
From that account, I can call in to our 3CX server, SIP-to-SIP. (OK)
From my desk extension, I dial the internal extension that will forward on to the new SIP acount. (Sort of)
This last step is where our firewall is yet again blocking traffic.
Firewall log when trying to place call:
On the handset, I get a 408 error returned, which on Sipgate's support pages, is listed as "login failed". http://www.sipgate.co.uk/faq/index.php?do=displayArticle&article=323&qw=408
(A call out from our 3CX SIPgate account to a mobile phone works correctly, so I'm guessing the login is referring to the target account).
So my next step will need to test this on a laptop that is not behind our HQ firewall and see if the problem still arrises. It may be the software firewall is also having an effect.
Should hopefully be able to do this later today, but if you've any ideas, feel free to suggest!
Kind regards,
Al
