# cnfjoin example

The following example sets up 4 resources, hosting up to 56 members with full capabilities at 14 members per resource. Up to 24 members can dial into the T1 link and join the conference. Four members are special members connected to the master conference. Twenty-four virtual members (member 24 to member 47) are available for playing and recording pcm files.

This example assumes you are using an AG 4000/1600 board connected to one T1 interface:

Step | Action
1 | Configure the system using agpi4cnf_2t1_1600.cfg and cnf_ag4_2t1_1600.cfg.
2 | In the nms\ctaccess\demos\cnfjoin directory, create 24 pcm files named sample24.pcm to sample47.pcm.
3 | Start cnfjoin by entering the following command at the prompt: cnfjoin –n 24 –m 4 –v 24

This example does not use all of the available resources (the resources can host a maximum of 56 members; only 52 members are used). The limitation comes from the IVR channel MIPS requirement. Only six DSPs are left for IVR (one is taken by ISDN and nine by conferencing according to ag4cnf_2t1_1600.cfg). The DSPs can support 48 channels (8 per DSP). Optimize the configuration by using fewer DSPs for conferencing and saving DSPs for IVR.
