I followed https://www.pjsip.org/pjmedia/docs/html/page_pjmedia_samples_recfile_c.htm link to record call and also convert some code to swift like, *var* cpFec: pj_caching_pool? *var* med_endpt: OpaquePointer? *var* file_port: UnsafeMutablePointer<pjmedia_port>? *var* pool: UnsafeMutablePointer<pj_pool_t>? *var* snd_port: UnsafeMutablePointer<pjmedia_snd_port>? * var* status = pj_init() *if* status != PJ_SUCCESS.rawValue { *return* (*false*, *nil*) } cpFec = pjsua_data().cp */* Must create a pool factory before we can allocate any memory. */* pj_caching_pool_init(&cpFec!, &pj_pool_factory_default_policy, 0) status = pjmedia_endpt_create(&cpFec!.factory, *nil*, 1, &med_endpt ) *if* status != PJ_SUCCESS.rawValue { *return* (*false*, *nil*) } pool = pj_pool_create(&cpFec!.factory, "app", 4000, 4000, *nil*) *let* rec = Recording.getNewSipBlanckRecording() *let* files = FileProvider.getRecordingUrl(fileName: rec.fileName)?.path *let* fileName: pj_str_t = pj_str(convertToChar(files)) */* Create WAVE file writer port. */* *let* str = String(cString: fileName.ptr, encoding: .utf8) status = pjmedia_wav_writer_port_create(pool, str, CLOCK_RATE, NCHANNELS, SAMPLES_PER_FRAME, BITS_PER_SAMPLE, 0, 0, &file_port); */* Create sound player port. */* status = pjmedia_snd_port_create_rec(pool, */* pool */* -1, */* use default dev. */* PJMEDIA_PIA_SRATE(&file_port!.pointee.info),*/* clock rate. */* PJMEDIA_PIA_CCNT(&file_port!.pointee.info),*/* # of channels. */* PJMEDIA_PIA_SPF(&file_port!.pointee.info), */* samples per frame. */* PJMEDIA_PIA_BITS(&file_port!.pointee.info),*/* bits per sample. */* 0, */* options */* &snd_port */* returned port */* ) *if* status != PJ_SUCCESS.rawValue { *return* (*false*, *nil*) } status = pjmedia_snd_port_connect(snd_port, file_port) It works fine and records the call completely in simulator, but in device it does not record for more than 1 second. anybody please help me.
