The PTT application enables channel selection. Channel Selection works on Kodiak Motorola Solutions powered PTT 9.1 (or greater/later) release for smartphones and 9.0.3 (or greater/later) release for feature phones. Channel Selection is also compatible with ESChat, which is mobile operator agnostic. A PTT provider may reach out to Sonim at [email protected] for more information on enabling channel selection.
Each RSM has a 3.5mm connector to connect a wired listen-only earpiece. The optional listen-only earpiece redirects the receive audio, while still transmitting audio through the RSM. This is necessary when in a situation where you don’t want audio broadcasted from the RSM.
