Ptlib build for windows mobile
by Victor Koh 29 Apr '08

29 Apr '08

Hi, all I have downloaded a copy of ptlib-v2_0_1-src.zip, and open the solution ptlib_2005.sln in visual studio 2005. I managed to build successfully with Win32 configuration. However the build is skipped when I changed Windows Mobile 5 or Windows Mobile 6 configuration. Is there any chance that any of us know the solution for this problem? Thanks and Regards Victor Koh ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

how to switch a point-to-point conference to multi-party conference
by Bian 24 Apr '08

24 Apr '08

Hi What is the standard way to switch a point-to-point conference to multi-party conference? (The condition is that the codec used in multi-party conference is not same as that in point-to-point call, for example, when in p2p call the endpoint communicate using H.264, and in multi-party confernce they use H.263 codec ) The SONY PCS endpoint's method is that the ep close all logical channels and re-issue capability, then re-open logical channel. I don't know if this is a standard method and if can cooperate with other endpoints. regards, bian ___________________________________________________________ 雅虎邮箱，您的终生邮箱！ http://cn.mail.yahoo.com/

Problem connecting with Polycom VSX 7000
by Abhishek Rohilla 17 Apr '08

17 Apr '08

Hi Has anyone ever tried t connect to Polycom VSX 7000 using H323+. I am trying to do it with both H.261 and H.263. It works fine with H.261 but with H.263 no image is displayed on Polycom side. The call statistics of Polycom show frame rate of 25 but video is blank. i guess there might be some problem with H.263 plugin. Polycom and my machine are on the same LAN. Does anyone have any idea about this problem? please help.

by Abhishek Rohilla 16 Apr '08

16 Apr '08

Hi Does anyone have any idea about how to know whether the remote side with which connection has been established supports H.239 or not. R Right now I try to open an extended session and check its return value. Is there any call in H323Plus which returns the H.239 capability status of remote side.Since we have already exchanged the capabilities, this information must be available somewhere. Please help!!

Message waiting indications(MWI) for Voicemail messages
by Anisha Kumar 07 Apr '08

07 Apr '08

Hi all , I have a requirement to support MWI in my device, which has support to both SIP and H.323. I see that there is H.450.7 Supplementary Service for that in H.323. But i am not sure practically it is being used in normal deployments. I am trying to find if Asterisk or any other opensource PBX support it.From my analysis i see that Asterisk does have support to MWI for SIP . But could not find out how is the notification done for H.323. Does anybody here have any idea how is it done for H.323 endpoints ? What is the normal means/procedure by which an IP-PBX provides MWI for Voicemail messages to the H.323 endpoints ? Awaiting an earliest positive response . Thanks & Regards, Anisha
