"" error while submitting iPhone apps from Xcode

My environment:  Xcode 4.1, iOS SDK 4.3, Lion

I am working on my first iPhone apps and when I tried to submit the iPhone apps after validation success, the following error is shown:


Good thing is I am not alone, the workaround is uninstall Xcode and reinstall again, that works for me.

sudo /Developer/Library/uninstall-devtools –mode=all

Now I am waiting for the app review and approval, can't wait to see my first app in app store!

Enable Video for CIPC on CME

My environment:  CME 8.6, IOS 15.1(4)M, CIPC 8.6.1, CUVA 2.2.2

It takes me some time to make the "broken line" in CUVA becomes connected again.  Try this if you have similar issue.

Using PVDM3 for Video Switching - CME

My environment:  IOS 15.1(4)M, CME 8.6 on 3945

The configuration of video switching DSP farm is similar to the voice conference DSP farm.  There are 2 different types of video conference, homogenous and heterogenous.  For homogenous, assuming the video codec and resolution for endpoints are the same.  For heterogenous, you can have different endpoints with different video codec and resolution.  In this post, I am trying to use 9971, 9951 with unified camera in a CME-only environment.

Since DSP farm can only registered to SCCP CME or UCM, telephony-service configuration needs to be done to allow the video conferencing dspfarm registered to it.  You need AT LEAST ONE SCCP PHONE to initiate the conference ad-hoc or meet-me conference.

1.  voice-card 0 configuration, the new dsp-reservation command reserves a certain portion of DSP for voice.  dsp-reservation 0 means all DSP will be used for video.

voice-card 0
 voice-service dsp-reservation 0
 dsp services dspfarm

2. voice-service voip configuration, allow sip and h323 interwork and enable sip registrar

voice service voip
 allow-connections h323 to h323
 allow-connections h323 to sip
 allow-connections sip to h323
 allow-connections sip to sip
 fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none
  registrar server

3. SIP CME configuration, remember to enable unified camera and video, either globally or per phone.

4. Homogenous video conference DSP farm configuration

6. Create ephone-template and apply it to the ephone who wants to initiate meetme conference

ephone-template  1
 conference admin
 softkeys hold  Join Newcall Resume Select
 softkeys idle  ConfList Gpickup Join Login Newcall Pickup Redial RmLstC
 softkeys seized  Redial Endcall Cfwdall Pickup Gpickup Callback Meetme
 softkeys connected  Hold Trnsfer Park Endcall Confrn ConfList Join Select RmLstC

7.  Create ad-hoc video and meetme video ephone-dn 

ephone-dn  10  octo-line
 number 3333
 conference ad-hoc video
 preference 1
 no huntstop
ephone-dn  11  octo-line
 number 3334
 conference meetme video
 preference 1
 no huntstop

8.  Try to initiate a meetme video conference from the SCCP phone, the let the 9971 phones call in the meetme number.  It will work.  I don't have enough PVDM3 for heterogenous video conference therefore I didn't try the ad-hoc video conference, if you have tried it and it works, feel free to share with me your result.  :)
