Reference for Taanit 2:5
מַעֲשֶׂה בִימֵי רַבִּי חֲלַפְתָּא וְרַבִּי חֲנַנְיָה בֶן תְּרַדְיוֹן, שֶׁעָבַר אֶחָד לִפְנֵי הַתֵּבָה וְגָמַר אֶת הַבְּרָכָה כֻלָּהּ, וְלֹא עָנוּ אַחֲרָיו אָמֵן. תִּקְעוּ הַכֹּהֲנִים תְּקָעוּ. מִי שֶׁעָנָה אֶת אַבְרָהָם אָבִינוּ בְּהַר הַמּוֹרִיָּה הוּא יַעֲנֶה אֶתְכֶם וְיִשְׁמַע בְּקוֹל צַעֲקַתְכֶם הַיּוֹם הַזֶּה. הָרִיעוּ בְּנֵי אַהֲרֹן הָרִיעוּ. מִי שֶׁעָנָה אֶת אֲבוֹתֵינוּ עַל יַם סוּף, הוּא יַעֲנֶה אֶתְכֶם וְיִשְׁמַע בְּקוֹל צַעֲקַתְכֶם הַיּוֹם הַזֶּה. וּכְשֶׁבָּא דָבָר אֵצֶל חֲכָמִים, אָמְרוּ, לֹא הָיִינוּ נוֹהֲגִין כֵּן אֶלָּא בְשַׁעַר מִזְרָח וּבְהַר הַבָּיִת:
It happened in the times of Rabbi Halaphta and Rabbi Hanina ben Teradion, that a minister advanced to the reading-desk and finished the whole of the blessing without any [of the congregation] answering thereupon, "Amen:" [a minister called], "Sound, O priests! sound!" [the minister who said the prayers continued], "May he who answered our father Abraham on Mount Moriah answer you, and listen [favourably] to your prayer this day:" [a minister called] "Sound an alarm, sons of Aaron! sound an alarm!" [the minister who said the prayers continued], "May he who answered our ancestors on the Red Sea answer you, and listen [favourably] to your cry this day." When the sages were informed of this, they said, "This was not our custom, except at the eastern door [of the Temple], and on the Temple-mountain [Mount Moriah]."
