Set uaConfig.maxCalls

[pdesaulniers-vertisoft]

config.json contains a maxCalls variable. However, this variable was not passed to PJSIP, which meant that the maximum number of calls was limited to 4 (the default value) :

    // endpoint.hpp

    /**
     * Maximum calls to support (default: 4). The value specified here
     * must be smaller than the compile time maximum settings
     * PJSUA_MAX_CALLS, which by default is 32. To increase this
     * limit, the library must be recompiled with new PJSUA_MAX_CALLS
     * value.
     */
    unsigned        maxCalls;
