[Asterisk-Users] How to make Polycom phones work with Asterisk as a SIP Client?

[Kanuri, Seshu (Company IT)]

Folks!

If you are using Polycom Phones, any model - 500, 300, 400, 600 etc,
please rememeber to add this line to your sip.conf entry.

Progressinband=no

Without this line, these phones may not work. Probably this one line may
fix most of the problems users are reporting on this forum about
Polycoms.
