[Asterisk-Dev] Agent channel question

[Ranga Rao Vutukuru]

Hi,

I was experimenting queues and agent channel.

I observed that the maximum group number in agents.conf can be 31. I
have also looked at ast_get_group function which limits group id to be
between 0 and 31. And also it does some bit manipulations.

Any specific reason why is it limited?

Can someone hint the logic behind shifting bits etc in channel.c as
well as chan_agent.c?

How to alter the limit without disturbing agent channel functionality?

Thanks in advance.
