[Asterisk-Users] TDM400P digium card

[Nora Lavelle]

Okay everyone - 

 

I'm moving away from using sipura 841 phones. I'm starting to test with
Polycom IP 501 phones. We plan to upgrade our server to a dual t1 but,
for now we have a digium tdm400P with 4 analog lines coming into it.  So
my question is will upgrading the IP phones with my existing digium
tdm400 card be enough to satisfy my users ?  or is it really a combo
deal needing to upgrade the TDM card and the phones? Basically, my users
say the phone system is unusable as is. The sound quality is choppy and
they can't understand people speaking on the other end.  I don't want to
swap out their IP phones and then find out they are seeing the same
issues with that. 

 

Any help as always is greatly appreciated everyone. 

 

Thanks ! 

Nora Lavelle
