1 Executive Summary This report provides the test results found to date for the ShoreTel IP PBX SIP Trunking

evaluation. The following is a summary of the issues and limitations found while

performing the test.

Issues/Limitations:

� All outgoing calls with from ShoreTel has FROM number with “+1” in front of it by

design. That causes XO to reject call as it can’t recognize user.

Example:

From: "User 2" <sip:[email protected]:5060>;tag=4a99fc6d

Workaround:

- “Trunk Group Dialing Rules” needs to be added via ShoreTel director to strip off

“+1”.

Detailed description of workaround can be found in ShoreTel configuration

section 6.1.

� Call Forward Always/BUSY/No Answer to PSTN to work requires special changes on

ShoreTel director to add ‘Diversion’ header.

Workaround:

- “Custom Parameters” – ‘HistoryInfo=diversion’ needs to be added via ShoreTel

director.

- “Enable Original Called Information" flag under ‘Trunk Group’ on ShoreTel

director also needs to be enabled.

Detailed description of workaround can be found in ShoreTel configuration guide

attached with test report.

� Caller-ID block feature for outgoing call from IPPBX doesn’t work. When dial with ‘9-

*67’ from extension, ShoreTel sends out call with FROM as anonymous in outgoing

INVITE.


4


Workaround:

- In case of caller ID block call when FROM header is

[email protected] XO requires ‘P-Asserted-Identity’ header with

known subscriber number to authenticate call.

- To make ShoreTel add 'P-Asserted-Identity’, create a new SIP Profile or use an

existing one.

If creating a new one, set the “User Agent:” parameter to “.*” (without the

quotes). Leave the “Priority:” parameter at a default setting of 100. Check the

box to the left of the “Enable” parameter by selecting it.

In the “Custom Parameters:” section adds the following entries (these are the

parameters that you would add to an already created profile):

EnableP-AssertedIdentity=1

These parameters are case sensitive, be sure to input them as noted without any

spaces. Save the entry by selecting the “Save” option at the top of the page.

� Inbound and Outbound fax call with T.38 failed with XO PKG1 (G.711 only).

This is a known XO limitation. There is a workaround available on XO side. Please

contact XO support.

� Fax over G.711 pass through (Inbound/outbound) doesn’t work with XO PKG2

(G729) failed as ShoreTel doesn’t fall back to G711.

No workaround found.

� ShoreTel server MUST require specific configuration change (windows registry

change) while it’s setup for PKG2.

Check ShoreTel configuration guide attached with test report for specific details.

� ShoreTel extension puts call on hold during conference process (to connect to 3rd

party) with MoH. For MoH ShoreTel sends re-INVITE with G.711. It sends another re-

INVITE with G.729 to take call off hold. But NBS stays with G.711. This means some

calls with PKG2 may end up with G.711.

Workarounds:

1. To remove ‘+1’ from FROM header.

• At the Director login screen, hold down the CTRL and Shift keys and click on the

"U" of User Id, if done correctly you should now see ***Support Entry***

displayed on the page, log in normally.

• Go to the SIP Trunk Group you've defined and edit it. Scroll to bottom of the

page, in the "Trunk Group Dialing Rules:" section, click on the "Custom" Edit

button.

• In the pop-up window enter ;10E and save the entry, that's it, you should now

see the FROM and DIVERSION headers in non-E.164 format without a leading

one.

2. To add ‘Diversion’ header.

• Go to the "Trunks" section, then to "SIP Profiles", and then click on the "New"

button.

• Define a "Name", set the "User Agent" to .* (just period then asterisk), check the

"Enable" parameter, in the "Custom Parameters" area enter the following (case

sensitive):

HistoryInfo=diversion


21


• Save the change.

• Go to the "Trunk Group" page and select the SIP trunk group you've defined for

your SIP trunks, select to modify. Then configure the "Profile" from

"_SystemTrunk" to the name you defined in step 2.

• Towards the middle of the "Edit Trunk Group" page you'll see a parameter

named "Enable Original Called Information", enable (check) this parameter then

save the changes.

3. Special Setting for PKG2 (G729)

On ShoreTel (windows) server:

- Open regedit on the ShoreWare server

- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Shoreline Teleworks\TDIMedia

- Add DWORD entry named "MaxNoOfG729Channels" and set it to a value of 28

hex (40 decimal). Please note that this entry is case sensitive and must be a

DWORD.
