I heard Allah's Apostle (way peace be upon him) pronouncing Talbiya for both Hajj and Umra. Bakr (one of the narrators) said: I narrated it to Ibn 'Umar, whereupon he said: He (the Holy Prophet) pronounced the Talbiya for Hajj alone. I met Anas and narrated to him the words of Ibn 'Umar, whereupon he said: You treat us not but only as children. I heard Messenger of Allah ﷺ pronouncing Talbiya both for 'Umra and Hajj.  

سَمِعْتُ النَّبِيَّ ﷺ يُلَبِّي بِالْحَجِّ وَالْعُمْرَةِ جَمِيعًا قَالَ بَكْرٌ فَحَدَّثْتُ بِذَلِكَ ابْنَ عُمَرَ فَقَالَ لَبَّى بِالْحَجِّ وَحْدَهُ فَلَقِيتُ أَنَسًا فَحَدَّثْتُهُ بِقَوْلِ ابْنِ عُمَرَ فَقَالَ أَنَسٌ مَا تَعُدُّونَنَا إِلاَّ صِبْيَانًا سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَبَّيْكَ عُمْرَةً وَحَجًّا  

"Anas said: 'I heard the Prophet reciting the Talbiyah for 'Umrah and Hajj together. I told Ibn 'Umar about that and he said: "He recited the Talbiyah for Hajj only. I met Anas and told him what Ibn 'Umar had said, and Anas said: "do you think of us as no more than children? I heard the Messenger of Allah say: 'Labbaika 'Umratan wa Hajjan ma'an (Here I am (O allah) for 'Umrah and Hajj together) (sahih)  

سَمِعْتُ النَّبِيَّ ﷺ يُلَبِّي بِالْعُمْرَةِ وَالْحَجِّ جَمِيعًا فَحَدَّثْتُ بِذَلِكَ ابْنَ عُمَرَ فَقَالَ لَبَّى بِالْحَجِّ وَحْدَهُ فَلَقِيتُ أَنَسًا فَحَدَّثْتُهُ بِقَوْلِ ابْنِ عُمَرَ فَقَالَ أَنَسٌ مَا تَعُدُّونَا إِلاَّ صِبْيَانًا سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَبَّيْكَ عُمْرَةً وَحَجًّا مَعًا

سَمِعْتُ النَّبِيَّ ﷺ يُلَبِّي بِالْحَجِّ وَالْعُمْرَةِ جَمِيعًا قَالَ حُمَيْدٌ قَالَ بَكْرٌ فَحَدَّثْتُ بِذَلِكَ ابْنَ عُمَرَ فَقَالَ لَبَّى بِالْحَجِّ وَحْدَهُ فَلَقِيتُ أَنَسًا فَحَدَّثْتُهُ بِقَوْلِ ابْنِ عُمَرَ فَقَالَ أَنَسٌ مَا تَعُدُّونَنَا إِلَّا صِبْيَانًا سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَبَّيْكَ عُمْرَةً وَحَجًّا  

[Machine] I heard the Prophet ﷺ saying, "Perform Umrah and Hajj together." So I informed Ibn 'Umar about it and he said, "He spoke the truth; I have heard the Prophet ﷺ saying the same." Then I met Anas and informed him about it, and he said, "They (the companions) know that better, but they do not like to act (upon that)." I asked Anas, "Had you done the same?" He replied, "Yes. And Allah's Messenger ﷺ said, 'Labbayka (i.e. I respond to Your call), O Allah, on behalf of 'Umrah and Hajj.'" (Sahih Muslim)
