Yes, using PCMA (that what is called in Yealink), I did check the document before

Hmmm. Have you got caller id populated in the yealink. Might be required. If blank it may well cause this too. Make sure label, display, register name are not blank

I have an n300 and never experienced this issue with aaisp. Not got a yealink although it has Poe which means I could relocate my dect hub, I'm too attached to my n300 which I've had 12 years !

AA would not be a problem (problem is only ZEN)
I have all that is required filled, and the unit is Registered (if I put wrong info it shows Failed registration, so I know the very few details are correct)

I really cannot get from this thread if it is only N300A that somehow works with Zen)

As per my post above - you need to set Caller ID number to your Zen phone number to call out.

Don't set any other Caller ID details (e.g. Name).

Incoming calls need your firewall opened on 5060 from voip.zen.co.uk (not voip2).

As per link above to AA support page for Yealink

There are ONLY fields for

Register Name Your phone number, +44...
Username Your phone number, +44...

I could not use +44 because registration would fail
Had to use just the number 017…… in both

There is no CallerID field anywhere

I will worry about incoming calls when I can make an outgoing one (and not failing with 603 error)

In reply to a post by wiggsc00:

What CODEC are you using on the yealink? AFAIK AA only support g.711 alaw

For the record, AA support G.722 just fine - at least AFAIK its working as I'm not sure how to check which is being used in a call but calls seem just as clear as POTS.

Actually they confirmed on this forum that they don't

You may think you're using g.722, but you're not, they only support g.711

"calls seem just as clear as POTS."
That'll be g.711 then, which is the long-standing standard codec used to digitise analogue POTS calls for onward transmission

Yes, don't use international format for your Zen number, just use 01nnnnnnnnn format.

I'm guessing from the AA screenshot that "Display Name" is your "Caller ID Name", so make sure it's blanked out.

Is there anything in the Advanced / Number Assignment / Handset Name tabs that looks like caller id settings?

make sure it's blanked out.

And if blanked out doesn't work, try putting just your number in (01nnn format)
