Google Voice help.... problems setting up voicemail greeting

[Pablo Mendez]

Hello, 

My wife and I have our first batch of direct mail going out this Saturday 20th. We are brand new wholesalers. 

We have our google voice number, but can not save a voicemail greeting

We click to record the greeting, it calls our phone, it prompts us to record, we start speaking... but everytime after about 20 seconds it hangs up. It does not save the greeting. 

Looked it up and it should allow us to record up to 90 seconds, and it is not saving. 

may be something simple we are overlooking, but any help is appreciated. Thanks.
