DID not working with new SIP server

Hi there,

I've been with Orbtalk in the UK for almost a year now & my DID has been working flawlessly with Voxalot.

Recently they changed to another SIP server and ever since then my DID doesn't ring through to my SPA3102 ATA.

If I bypass Voxalot & configure my ATA with the new SIP server and same username/password it rings properly. I put things back on Voxalot and the caller gets an error tone message in in their handset.

The only difference I can see it that the ATA allows me to put a proxy server in which Voxalot doesn't. Also Orbtalk have told me to use 711u as the codec.

I notice that the Voxalot codecs don't show 711u specifically but should this make a difference?

It shows registered in my account and I have tried de-registering it with Voxalot to no avail.

I am desparate because my aged Mother uses my DID to keep in contact with me.

Thankyou

Do you know when they changed to the new server?
I noticed some problems between my Asterisk & Orbtalk recently and had to put mysipswitch in the middle. That solved my registration issues and eliminated error messages.

The new servers have a new name too.

Can you tell me what codec is being negotiated between Orbtalk & your Asterisk box?

I notice that the codec choices in Voxalot are "g729;g723;g726;ilbc;gsm;ulaw;alaw".

What I'm curious about is it doesn't list 711u specifically so maybe that's the problem?

I don't have any solution in mind, but was wondering how the RTP connection is supposed to work. Is Voxalot supposed to send a re-invite to get the RTP going directly between your ATA and Orbtalk? If so, it would be Orbtalk and your ATA that need a common codec.

Hi boatman,

I think the RTP voice packets go between my ATA & Orbtalk's PSTN switch but I don't think the issue is between Voxalot & Orbtalk.

Between my ATA & Orbtalk now works for one of the migrated accounts but it doesn't work when I put Voxalot in the middle

This is what I have from them (from mss log):

Code:

m=audio 17984 RTP/AVP 8 0 3 97 7 110 5 10 18 112 111 101

a=rtpmap:8 PCMA/8000

a=rtpmap:0 PCMU/8000

a=rtpmap:3 GSM/8000

a=rtpmap:97 iLBC/8000

a=fmtp:97 mode=30

a=rtpmap:7 LPC/8000

a=rtpmap:110 speex/8000

a=rtpmap:5 DVI4/8000

a=rtpmap:10 L16/8000

a=rtpmap:18 G729/8000

a=fmtp:18 annexb=no

a=rtpmap:112 AAL2-G726-32/8000

a=rtpmap:111 G726-32/8000

G711A (PCMA) is always negotiated for me.

RTP is coming from 217.14.138.16

Thanks green that confirms what Voxalot have said.

Last night I tried unregistering my three OT accounts and then registered them again, this time with the eu server. It didn't make a difference.

I then tried deregistering one of the non ringing accounts & bypassed Voxalot & could get my ATA to ring. I put it back on Voxalot, registered my account again but the incoming calling stopped working again.

I'm interested in this mss service as it's free but can I kindly ask how to configure to work with my ATA & how to set up my Orbtalk accounts with it?

Thankyou & best regards
