Hi everybody,

i'm getting mad trying to make it works this configuration about fxs and sip.

I can register the fxs on sip server , i can call from fxs to a phone also registereded on sip server but not the other way , form the sip phone to the fxs.

Under the 'session protocol sipv2' command, enter the 'sip-server' command.

Refer to

http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a0080080b29.html

for the syntax.
