Whether S1700 switches are GE switches
If you understand the naming rules of the S1700, you can determine whether an S1700 switch is a GE switch or not based on its model.

What should I do if the one-way audio or no audio problem occurs on IP phones under the U1900 or on analog phones under the IAD?
When phones under the U1900 (including phones registered with the U1900 through the IAD) make outgoing calls through PRA, SS7, AT0, R2 trunks, voice streams are transmitted between the terminal (including the IAD) and the U1900. In other scenarios (making intra-office calls or making outgoing calls through the SIP trunk), all voice streams are transmitted between phones or between the phone and the peer SIP gateway. Check whether the IAD and IP phone can ping each other or whether IP phones can ping each other. Check whether any ports are restricted.

Whether the S1700 functions as an aggregation switch
Can an S1700 switch function as an aggregation switch? The S1700 mainly applies to individual users and small- and medium-sized enterprises, functioning as the access switch. When a few terminals are connected, the S1700 can function as the aggregation switch. When many terminals are connected and the traffic volume is high, you are advised to use switches with higher specifications than the S1700 as aggregation switches.
