We are implementing a UCM 7.1 cluster that integrates with AD. The telephone numbers within AD are formatted as +E.164 (i.e. +14085264000).
We have issues trying to have users directly dial these numbers from their phone. A translation pattern have been setup to remove the + sign but still calls would fail.
Is there some limitations that IP phone aren't able to dial +E.164 formatted numbers? Directory Lookup Rules are not of much help as well.
Appreciate any feedback.
Thanks and kind regards
Assuming you are running a recent SCCP load on the phones, the translation pattern should work. I know in older phone loads, especially SIP there were problems with this.
Use the Dialed Number Analyzer tool in the serviceability page to verify the call flow. If that checks out, investigate what exactly is happening in the CCM traces.
Directory Dial Rules do not apply to corporate directory on the IP Phone. That is only for third party apps which need to resolve a name given a number.
Thanks for response, Adam.
Did run DNA and the translation pattern is matching the correct path. On CCM traces, couldn't seem to find the dialed number.
I have so far tested on CIPC and older 7940 phones. You may be right about the older firmware. I am waiting for a colleague to bring in newer 79x2 phones and run the test again.
Just to add to Adam's comment - E164 dial pattern is only supported on Gen3 phones. So, yes it will work on a 7942 but not on CIPC.
I looked at the CCM traces again and found that the digits received from the phones doesn't include the '+' sign the reason that the translation pattern is not matched thus failing the call.
7940's are sending the dialed digits BTW.
I'll test again with 79x2's and see what happens.
This is the enhancement request for CIPC

I too am facing with the same issue where I need to truncate the +70xxxxx, but the translation pattern doesnot accept the
"+" sign. Do we have document or configuration steps to achieve this.
You need to enter it as \+ I think.
Please rate helpful posts..
For pattern matching you will need to include \ before the + as an escape character. + (without the \)is considered a wildcard and cannot be at the beginning of a pattern.
Your translation pattern should be \+70XXXXX
