SPA941 problem

Hi,
I am using a Linksys SPA941 with the latest firmware and have a problem.
As soon as I hangup a call (inbound or outbound) the phone cannot make or receive any calls. I have to reboot it for it to work with PBXes again - but other providers work fine.

I have rebooted PBXes, changed extension settings but nothing works.
Any ideas?

Thanks,
Dimitris.

RE: SPA941 problem

Well Dimitri, that is quite strange, since I have a few SPA-942s registered on various PBXes accounts and they work properly.

Can you port-forward its' web interface so I can take a look at its' settings?

RE: SPA941 problem

I think it has something to do with the actual hardware.

When I press the # key at the end of a number to dial, I hear a very long tone (5 sec) and then it does nothing.

However, this is not a problem with other providers.

I also have a SPA962 registered and that works fine, with the same settings actually.

Don't have access to the router unfortunately so can't port-forward but can send you a saved page of SPA941 settings.

Σε ευχαριστω!

RE: SPA941 problem

If you think it is hardware related, a factory reset to its' default values, might cure it. You have nothing to loose by trying.

If that does not cure it, then upload the pics somewhere for me to look at. Keep in mind that some default values of the SPAs are not at their optimum values. So some tweaking is needed after the reset.

Let me know how it goes.

Καλή επιτυχία.

RE: SPA941 problem

Thanks for the interest.

I did a restart, a reboot and a factory reset.
Same problem persists after all of these.

I will check again and let you know.

Σε ευχαριστώ για το ενδιαφέρον

EDIT: It seems to be working now. No more long DTMF tones for the # key. Sometimes an outgoing call times out but redial works fine.
Incoming calls work fine too.

RE: SPA941 problem

So I guess the reset to factory defaults worked. However, there are a couple of settings for SPAs, that make them to work better and happen to be different from their defaults.

Let me know if you are interested.

RE: SPA941 problem

What are these setting.
Definitely interested, thanks for the update.

RE: SPA941 problem

Here you go:

• At the SIP tab, in the section RTP Parameters -> RTP Packet Size: 0.020
• At the Regional tab, in the section Control Timer Values (sec) -> Reorder Delay: 255
• At the Regional tab, in the section Miscellaneous -> Daylight Saving Time Rule: start=3/-1/7/3:00;end=10/-1/7/4:00;save=1
• At the Ext (1-4) tabs, in the section Audio Configuration -> DTMF Tx Method: AVT

RE: SPA941 problem

Hi Diafora,
thanks for the settings.

FYI, I think that the problem is broader than the SPA941.
I have also a SPA962 and a SPA3102 which sporadically show the same problem.
Rebooting sets things straight but that's hardly an efficient solution.

This never appeared before a month or two btw.

Dimitris.

RE: SPA941 problem

Dimitri,

• On which server is your account hosted? (What is the number X of the wwwX.pbxes...)
• Who is the broadband provider that these phones connect to the Internet from?

RE: SPA941 problem

1) www1
2) Two ISPs: On Telecoms and Tellas

RE: SPA941 problem

Hi,
@ Diafora,
Sorry to resurrect an older post but you mentioned some ATA settings in here which I would like to clarify.
Specifically the reorder delay of 255, I understand that this setting = infinite. I have seen this mentioned before on other forums but no explanation.
What would be the advantage over the default (of several seconds) in practical terms ?
Regards
Ron

RE: SPA941 problem

Hey Ron,

The practical advantage of setting the Reorder Delay to 255 is for the phone to hang-up immediately after a call is completed, without waiting for 5 seconds.

The relevant entry in the www.spa9000.com to the question: "Can I make my phone automatically return to on-hook after the other party disconnects?"

is "Yes, by setting the Reorder Delay timer (in the regional tab) to 255, the phone will automatically return to on-hook after the remote party disconnects".

RE: SPA941 problem

Thanks Diafora, thats useful.

RE: SPA941 problem

Hey Dimitri,

Is the issue with the SPAs still ongoing via these two ISPs?

RE: SPA941 problem

Hi Diafora,
it was actually a bad connection which wasn't noticed in other software.
When I used a VPN for something else, the connection kept dropping, which explains the bad performance of the SPA941.
I now use On Telecoms and that works wonders.

btw, do you know if any mobile operators are blocking VoIP in Greece?
Just FYI, I can't get sipdroid to register and make a call on Vodafone 3G which is strange.
