[asterisk-users] Asterisk extension not found problem...

[abhinav anand]

Hi All,

I am using Asterisk for one of my projects in OpenBTS. I am having the age
old problem of "extension not found" when try to make
a call from one registered SIP phone to other registered SIP phone (two
mobile phones connected to Asterisk via OpenBTS).

The exact error thrown on Asterisk CLI is
*"chan_sip.c:20039 handle_request_invite: Call from [IMSI310410270465840] to
extension "2103" rejected because extension not found"*

I have provisioned for both the phones in *sip.conf* and
*extensions.conf*under context
* [sip-external]* but I suspect whatever entry given in extensions.conf,
that file is not getting parsed and extensions are not read.

I have tried all the methods suggested by others in the Asterisk User
community but still the problem remains same. If anybody knows the solution
to this
one, please let me know.
