[Asterisk-Users] Call Manager Express Peer

Hi,

There seem to be some codec incompatibility.
On *, you define alaw and you set ulaw on the Cisco.

Set both to same or add the other codec on (at least) one side.
Try if that solve it

Ex:
Add "allow ulaw" on * after the "allow alaw"
And / or
Add "codec g711alaw" on Cisco above the "codec g711ulaw"

If I remember correctly, Cisco parse the codecs according to their entry
onder. Asterisk orders according to alphabetical order.

If you do not need both codecs, set only one to simplify.

I have the following configuration and am obviously missing something 
small that is causing * not to work as expected.

I have the following defined in sip.conf

[ccme-in]
type=peer
host=10.0.9.1
context=devel_in
disallow=all
allow=alaw
nat=no
canreinvite=yes
qualify=yes

and [devel_in] is defined in extentions.conf

However when I try to call via the dial peer I have configured on the 
cisco (below) I get :

Feb 22 18:37:40 NOTICE[31486]: pbx.c:1318 pbx_extension_helper: Cannot 
find extension context 'default'

Which is correct, meaning the context declaration is not being respected.

------
dial-peer voice 101 voip
 destination-pattern 10.
 session protocol sipv2
 session target ipv4:10.0.0.133
 dtmf-relay rtp-nte
 codec g711ulaw
 no vad
-------

My bad or something else ??

TIA,

Nathan.

Here is a sip debug for that peer:
