Cannot complete inter office Conf call

Hi all,

I am getting an error when trying to make a conference call to another office. If I go to the PSTN and make a conf call it works.

I looked at the region codec's and they say to use g.729 to the other regions

CCM 4.1.3, h.323

Thanks,

Randall

Re: Cannot complete inter office Conf call

most probably you're using a SW conference bridge that only supports G711.

Add a XCODER or use a HW CFB

Re: Cannot complete inter office Conf call

Here is another question. The user just said it works on his desk phone but not P Comm. 2.0

Re: Cannot complete inter office Conf call

it probably has the optimize for low BW configured under the IPC preferences on the computer

that checkbox causes IPC to use G729

I initially tried that, with no luck.

Re: Cannot complete inter office Conf call

When the 2nd call answers i press the confrn button. Should there be a join button in the template? Maybe I have the wrong button.

Thanks,

Re: Cannot complete inter office Conf call

join is used when you establish calls using the hold, new call method. if doing conference press cnf 1 time, dial then press cnf again to connect parties

Re: Cannot complete inter office Conf call

OK, just wanted to check.

so why would the desktop work and not the IP Comm.

MRG, MRGL, no access to the SW CFB, IPC and CFB in different regions

Re: Cannot complete inter office Conf call

I am looking at the MRGLs. US has 2 groups. China has 3. The top group in the China list is the china resource group and the other 2 are the same as US.

Thanks,

RC
