Linksys SPA3102

The following configuration has not been tested for PSTN failover. The FXS port is registering to a sipXcom 14.10 PBX and handles inbound/outbound fax transmissions as well as voice.

The first page as seen below shows the firmware and hardware version that this unit was running.

Click on Admin Login and Advanced and then click on the SIP tab under the Voice settings. The following page will be displayed:

Set RTP Packet Size to 0.020 and then click on the Submit All Changes button at the bottom of the page.

Next, click on the Line 1 tab. Set the Line Enable to yes, set any QOS settings you may require, set the SIP Transport to UDP, set the Proxy to your SIP domain (for SRV sipXcom setup), set Reigster to Yes, set Use DNS SRV to Yes, set DNS SRV Auto Prefix to Yes.

Set the Display Name to what you want local phone users to see for a user name, set User ID to the user's PBX extension, set the Password to the SIP password (not the PIN!), set Use Auth ID to no, set Auth ID to the user's PBX extension.

Set the Preferred Codec to G711u, set Use Pref Codec Only to yes.

The following dial plan will dial just about any valid number (depending on you Dial Plan in the PBX) . Just before the end of the page set the Dial Plan to:(*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)

Click on 'Submit All Changes' when done with this page.

All of these settings can be seen in the following three screen shots:

 

 

 

If your DNS is configured properly the gateway should register and be able to make calls at this point.

Linksys / Sipura PAP2

We need more detail here...

PAP2 Notes:

PAP2 Settings to adjust.

Under the sip tab:

RTP Packet Size: 0.020

Under the line settings:

DTMF Process INFO: no
DTMF Process AVT: no
DTMF Tx Method: Auto
DTMF Tx Mode: Strict

I think that is all I changed from the defaults, and these settings work on both of my PAP2's. For some reason this does not work consistent with all the Linksys/Sipura models, for example I ended up using different settings on a SPA 2100.

    Hi Jim, are you sure there is a sipXcom 14.10.2 or it would be 14.10.1 at present?

    Copy & Pasted from the GUI...   I did a yum update recently - were there additional builds?

    Not after sipXcom 14.10.1 (released March, 7th 2015).

    I think that string (14.10.20150226031614) is confusing because it reports 14.10 2015 02 22 03 16 14 and that only means that you're playing with a sipXcom built that initially was 14.10 (generated/built on February, 22nd 2015) without showing the exact Hot Fix Release it currently has (14.10.0 or 14.10.1 or whatever Hot Fix is going to come next). At least this is what I understand reading that string. As example, my system is 14.10.1 because I know I updated it from 14.10 to 14.10.1 but it reports the same build string your wrote. I don't know if there is a place to look to understand exactly version Y.M.HF version the sipXcom is running (probably examining the yum update history and yum repo files).

      Thanks for the clarification Davide!  Totally makes sense - just lack of understanding on my part.  Editing to 14.10 and we'll leave it at that - for now (smile)
