Hello,

I have some 433AHs with R52nM miniPCI cards as single APs.

The configurtaion is very simple.

Mode: ap bridge
Band: 2.4GHz-B/G
One bridge with ports ether1 and wlan1.
All the other settings at default values.
RouterOS 4.17.

I have a PC running 3CX phone system and i have a Cisco WIP310-G2 wireless ip phone.

The problem is that during a call the other person in the line can hear me, but i cannot hear him.

With iphones and android phones using the 3cx sip client there is no problem.

I tried a 2nd Cisco WIP310-G2 but still the same. I tried using a WRT54GL as AP and no problem.

Then i changed the R52nM with XR2 and no problem!

So, the problem is only when i'm using R52nM with Cisco WIP310-G2.

Do you have any idea what is going wrong? Maybe the drivers of R52nM doesn't support this Cisco phone?

Thank you in advance,
Tasos

Any idea?

I have the same problem with cisco wip310 & miktorik rb411 , they can hear me i cant hear them , with other access point i dont have any problem , i think i will replace all my mikrotik access points, this is very annoying...

I have tried several miniPCI cards, R52nM, R52, CM9, XR2.

The problem with one way voice was only with R52nM, but with the other cards there was a problem too.

I have a group with some IP Phones and 3cx phone system.
When there is an incoming call, all the other phones ring simultaniously, but the WIP310 starts ringing after a few seconds and if i pickup the call from an other phone the WIP310 keeps ringing. Sometimes it doesn't ring at all.

I tried both RouterOS 4.17 and 5.11.

With a linksys wrt54gl it works excellent.

So, the problem is in routerboard for sure.

This may be an next issue of the Atheros 9220 chpset. Dbii network replace their F52N-PRO to the older F50N-PRO.
