Help with component symbol

[Ravi Upadhyaya]

 

 

 

 

My cordless phone (Panasonic) got damaged due to a thunder storm – probably due to a thunderbolt. It burned a few components on the board. A PTC thermistor had burnt and I replaced it. But I can see a couple of more components that are burnt. One of the components has a symbol that I am not sure of. Request your help in identifying it. I have marked it in the attached picture. Thanks a lot in advance.

Most likely a spark gap, it could use a spark gap component, or it just could use the gap between two pcb tracks
