In short: were there female telephonists at Auschwitz?
The following is the relevant trial material I could find:
Deposition of Helena Koper, The Trial Of Josef Kramer and Fourty Four Others - Seventeenth Day Friday, 5th October, 1945, http://www.bergenbelsen.co.uk/pages/TrialTranscript/Trial_Day_017.html#Day017_Kopper2She [Irma Grese] was Blockführerin in Auschwitz and subsequently in charge of the punishment company in Auschwitz from 1942 to 1944. She was in charge of the punishment company when working outside the camp for six months in 1943. The remainder of the time she did not go outside. I was also in the punishment company and during the time that Grese was in charge when working outside we were employed outside the camp in a sandpit. There were 700-800 women working in this company some of whom were detailed to dig sand and fill iron trucks with the sand and others had to push these trucks along a narrow gauge railway.
[…]
She [Irma Grese] was responsible for at least 30 deaths a day resulting from her orders to cross the wire but many more on occasions. It was always my job, ordered by Grese, to count the dead and I, together with some other women, used to load the bodies into one of the railway wagons after working hours. The bodies were subsequently removed by ambulance. I know two of the women who helped me on these occasions. Their names are Canina Stasicka and Karola Mikot. I saw them last on 6th June 1945 in Belsen Camp. Both are Polish Aryans. Their Auschwitz numbers tattooed on their arms are 18565 [18565 belonged in KL Auschwitz to Wanda Kalisz, who was liberated in Auschwitz in 1945] and 18566 [18566 belonged in Auschwitz to Kubasiak, Zofia born 03 June 1900 in Zalas] I do not know which of them had which number.
Helena Koper examined by Major Cranfield (defense), The Trial Of Josef Kramer and Fourty Four Others - Forty First Day, Friday, 2nd November, 1945, http://www.bergenbelsen.co.uk/pages/TrialTranscript/Trial_Day_041.html#Day040_KopperThen you say Grese was in charge of a punishment company from Auschwitz from 1942 to 1944. Do you still say that that is not true? - She was for seven months the leader of the Kommando S. K, that is Strafkommando, punishment kommando.
Now seven months is not the same thing as two years. Do you still say that Grese was in charge of the punishment company at Auschwitz from 1942 to 1944? - Yes, I do.
What is the difference between the punishment company and the Kommando S.K.?
THE INTERPRETER: That is the same thing. When I translate it it will be the same thing.
MAJOR CRANFIELD: Just ask her the question.
COLONEL BACKHOUSE: Well, it is the same words for both.
MAJOR CRANFIELD: Is it the same word that she has used?
THE INTERPRETER: Yes.
MAJOR CRANFIELD: (To the witness) I suggest to you that Grese did not come to Ravensbrück until the summer of 1942, and did not come to Auschwitz until March, 1943? - And I still maintain that I remember Grese in Ravensbrück from 1940, when she was walking with her riding-whip and carrying out parades in front of Block No. 10. [Koper had just previously answered she knew Grese in Ravensbrück from 1941]
I suggest to you that at the time you say she was a Blockführerin in Camp A and Camp B, she was in fact on telephone duty in the Blockführerstube? - In Auschwitz no female personnel were employed on telephone duties, only male personnel. For instance Kasainitzky, Weingartner, Rhatus and Herschel.

I remained in Auschwitz until January, 1945.
Will you tell the Court the various duties you did during the period you were at Auschwitz? - At first I did telephone duties in the Blockführer's room. For two days I was transferred as a sort of light punishment to be in charge of the Strafkommando which carried stones from outside into the camp. During 1943 I had the Strassenbaukommando, and I also had the gardening working party for about two months in the autumn. In December, 1943, I was in the parcels office censoring mail in place of Volkenrath, and from May until December, 1944, I was in Compound "C."

Were you not in charge of a Strafkommando out of the camp for a great deal longer than you have told us? - No.
You know Koper quite well. Was she not at Auschwitz whilst you were there for a long time, and with you all the time you were at Belsen? - Yes.
She would hardly mistake you for somebody else, would she? - I do not know.
Were you not in charge of a Strafkommando employed on working at a sand-pit? - I explained already that I was in charge for two days of a Strafkommando which was working in bringing in stones from outside the camp, and that was a punishment for myself.
[…]
It would be very unusual to have a selection without an Aufseherin, would it not ? - No, on the contrary.
Who would do all these duties on the selections if there were no Aufseherinnen present? - As I was not interested in it I do not know.
Then why do you say it would be unusual for an Aufseherin to be present if you were not interested? - Because all the Aufseherinnen had their jobs with outside Kommandos or in the administration office.
Is that not just why you had to be brought in on occasions? - No.
You would be the handiest person, of course, when you were in the Blockführerin's room? - I had my duties; I was not allowed to leave the telephone.
I suggest to you that on selection in Block 9, Camp "A," two girls jumped out of the window and that you went up to them and shot them whilst they lay on the ground? - No.
