SIP Registration failed.

My Yealink W52P has lost registration and cannot re-register.


I can ping both sip1.freshphone.co.za and 41.221.5.107.  SiP ALG is disabled in my router.  ISP is CoolIdeas.


Acc number is 27872384058






Hi Phillipa, I see the ticket which you have open is being actively worked on. 

I'm in a similar boat - am setting up a Gigaset AS690, and whether I use a manually configured profile or I use their built in Fresh Phone profile I am unable to authenticate. The Tenda AC1200 router I'm using doesn't even support SIP ALG.

I replaced that with a D-Link DSL-124, which allowed me to register and make calls,  but only when SIP ALG was _enabled_. Disabling it meant that we couldn't register at all.

Incoming and outgoing calls worked this morning until they suddenly stopped, registration failed, and has been off since. My ticket to check whether the IP has been blocked is still waiting.

The Gigaset lacks any kind of logging facility, so it's hard to see where or why it's failing. Is there any way to get better feedback on errors from the tms portal?

Hi Tyrone


It does however, seem to be online right now



Hi Tyrone


The phone won't register due to one of these reasons


1. Credentials are incorrect

2. SIP ALG on the routers Firewall isn't disabled

3. The network has been blacklisted due to misconfiguration of an extension

4. No internet

5. Faulty ethernet cable

6. Phone is broken or set up incorrectly

7. No electricity

8. freshphone is down

9. ISP is blocking VoIP






We had finally figured out the problem.  I had enabled both extensions for dial-out, but the Freshphone package only allows one extension to dial out.  Once we changed that setting, all was OK.

Hi having the same issue now with my client, everything is perfect on the yeaLink side. Dont it for a few people but getting Reg failed. 
I am able to ping sip1.freshphone.co.za from his network so I take it he has not been blacklisted. 


Any idea of what we can do 



Yes thank you.  Unfortunately I am away from home a lot, so we have been unable to schedule a time for them to do an online session on my setup.

Hi Willem, I see this has been taken to a ticket to get this resolved for you. 

It has now registered, but I cannot dial out at all.
