Noise on remote side

Im currently having a very strange issue at a clients site
The current setup is as follows

PABX: Trixbox CE 2.8.0.3 with Sangoma A500 BRI card with 2 incoming ISDN lines
Handsets: Snom 300 & Snom 360 all running the lates version 7 firmware.

The problem is as follows:

If someone phones into the PABX on the ISDN lines, the call is answered by the receptionist and then tranfered to the right extention. If the transfer is done as an attended transfer (*2) then the person who called in will experience a noise/distortion on thier end in terms of voice quality.

The problem seems to be particularly bad if instead of the receptionist answering the call, a group pickup (*8) is done from another phone and then an attended transfer is made.

The problem does not seem to exist when doing a blind transfer on the call.
The noise is only experienced by the party calling in and not by the extentions
The noise only occurs once the call has been transfered.

Any help on how to resolve this issue would be appreciated.

Regards
Heath Jordaan

Hi Heath, This sounds to be

Hi Heath,

This sounds to be on the sip side of things that is causing this issue. So lets start by setting up a call from SIP-->SIP and then doing an attending transfer to another sip phone to see if this has any noise in it. If this issue does not occur on the SIP->SIP attended transfer then send an email into techdesk@sangoma.com and insure you reference this post.

thanks Marc, Im busy testing

thanks Marc,

Im busy testing that right now and will let you know.
Thing is this noise doesnt seem to appear all the time which is annoying.

We have other switchboards with identical hardware and software (pabx and phones) out there that do not have this issue at all which is complicating matters.
