Informations about Lync dial plan support of UCS 4.0.2

[PeterFischer]

In the release notes of the UCS 4.0.2 I found the new features

"76730 Added support for Lync normalization rules and dial plans."

"77038 Added support for early media followed by local ring back."

Where can I found more informations and documentations to this features?

Could it be that the first named feature is the cause why our SL8450 aren't able to dial in our Lync environment after software upgrade?

In the Lync trace I see that suddenly the SIP INVITE is missing the leading '+'.

After downgrade software dialing is possible again and  '+' in SIP INVITE from SL8450 is present again.

Thanks,

Peter

Hello Peter,

welcome to the Polycom Community.

From the UCS 4.0.1 Admin Guide:

voIpProt.SIP.requestURI.E164.addGlobalPrefix 0 or 1

If set to 1, ‘+’ global prefix is added to the E.164 user parts in sip: URIs.

Above will add the "+" again if set to ="1"

I assume the documentation for LYNC will be updated to reflect this change in behavior.

Hello Steffen,

although setting the recommended voIpProt.SIP.requestURI.E164.addGlobalPrefix to 1,

the SL8450 aren't able to dial after upgrading to 4.0.2.

In Lync trace I see that after software upgrade is again missing the E.164 '+'

What could be the problem?

Thanks,

Peter

Hello Peter,

I am no where near my LYNC Test Server so I am unable to test.

Have you tried using the digitmap to add the + instead?

I have the same problem on this firmware (4.0.2), we have no + at the start of our numbers when dialling despite using voIpProt.SIP.requestURI.E164.addGlobalPrefix="1". The digit map cannot be used to add + as it only supports 0-9 * #.

I've followed the Lync setup guides for Polycom UC to the very letter but the Polycom ignores the Lync dial plan normalization rules, is there something I'm missing here?

Hello all,

I am nowhere near a phone but you should be able to use R+R in the digitmap in 4.0.2 Rev B

Hello Peter,

before UCS 4.0.2 Rev B Standard US Dialplan if used with LYNC + would be added:

dialplan.digitmap = [2-9]11|0T|011xxx.T|[0-1][2-9]xxxxxxxxx|[2-9]xxxxxxxxx|[2-9]xxxT.

Since UCS 4.0.2 Rev B:

dialplan.digitmap=RR+R[2-9]11|0T|RR+R011xxx.T|RR+R[0-1][2-9]xxxxxxxxx|RR+R[2-9]xxxxxxxxx|RR+R[2-9]xxxT.

or if you use a LYNC Line on Line 1 and SIP on Line 2:

dialplan.1.digitmap=RR+R[2-9]11|0T|RR+R011xxx.T|RR+R[0-1][2-9]xxxxxxxxx|RR+R[2-9]xxxxxxxxx|RR+R[2-9]xxxT.

dialplan.2.digitmap = [2-9]11|0T|011xxx.T|[0-1][2-9]xxxxxxxxx|[2-9]xxxxxxxxx|[2-9]xxxT.

Hello Steffen,

sorry for my delayed response: your example for a integration of  '+' into SL dialplan works for me, so we are now able to use the 4.0.2 software with Lync.

Thanks,

Peter

Also be aware that extension dialing now works with Lync and 4.0.2.   See this blog article for details and configuration instructions:
