1. A method comprising:

  • receiving, by a processor of a first deployment site of a push-to-talk (PTT) platform, from a PTT client protected by a firewall that does not permit unsolicited network traffic, a registration request to establish a primary notification channel;

    establishing, by the processor of the first deployment site, the primary notification channel for the purpose of signaling between the PTT client and the PTT platform;

    receiving, by a processor of a second deployment site of the PTT platform, from the PTT client protected by the firewall that does not permit unsolicited network traffic, a registration request to establish a secondary notification channel;

    establishing, by the processor of the second deployment site, the secondary notification channel, wherein the secondary communication channel utilizes a UDP transport protocol;

    determining, by the PTT platform, that the primary notification channel has failed;

    providing an indication of the failure of the primary notification channel to the PTT client over the secondary notification channel; and

    re-establishing the primary notification channel, wherein the re-establishment of the primary notification channel is initiated by the PTT client protected by the firewall that does not permit unsolicited network traffic.
