What is the limit of devices that I can pass to the Dial Application as per this syntax
“Dial(Technology/Resource&[Technology2/Resource2[&…]],[timeout,[options,[URL]]]])”
that referenced at this link Dial - Asterisk Documentation
The limit isn’t the number of addresses, but the total length of the parameters, after variable substitution, passed to the application. I think it was around 255 bytes at one time but that may have changed, in response to the longer addresses produced by PJSIP_DIAL_CONTACTS.
