Soundstation 2w Wireless Conference phone

[Anonymous]

I have a Soundstation 2w that when a call is made from this phone dialing to a Adtran 706 or 712, the call goes directly to voicemail. If I dial from the Soundstation 2w to a Polycom 601 it works just fine. Any suggestions where I should look?

lisavision,

I am assuming all of these phones are off of the same unit.  If that is not correct please let me know.   If it is a NetVanta 7100 (or other AOS voice product)  I would need to see the current configuration of the unit and the output from a debug sip stack messages and debug voice verbose while the problem is recreated.  If it is on a UC server I would need to see a packet capture from the server and possibly the swlog.txt file that corresponds.  If you do not have any private sensitive information (public IPs, passwords, etc) you can attach this information in a reply.  If you do have sensitive information in the configurations and debugs you can either strip it out before attaching it or you can upload it to our FTP server from the instructions below.  I would need to know the exact file name(s) if you upload them to the FTP server.

Open Internet Explorer web browser
Type the following URL:  ftp://ftp.adtran.com
Double-click the "Incoming" folder

Press Alt, click View, and then click Open FTP Site in Windows Explorer

Drag and drop files from PC into the Internet Explorer window

Thanks,

Matt

The issue was fixed by correcting the RTP packet size on the phone from 0.030 to 0.020.

Thanks for posting the resolution.  Just to give some additional information to anyone else who comes across this post, this is related to the ptime sent in the SDP.  It would look like the portion highlighted in red below in a debug sip stack messages:

ADTRAN IP 700 phones do not support anything other than a ptime of 20 ms.  This is denoted in the as follows:

Calls with packetization periods other than 20ms will be disconnected by the phone with a BYE response, as only 20ms packetization periods are currently supported.

Thanks,
