[Asterisk-Users] Suddenly a problem with outgoing calls made from Cisco phones...
Hi all!
Quite a mystery. The following happened when I was on holiday, and no one else
has changed any configs of either Asterisk or the Cisco's in the building...
The situation: Incoming works fine on all phones. Outgoing only works from
non-Cisco phones. When calling from a Cisco phone to an external phone, all the
Cisco-user hears is a ticking crackle and
after about a minute the phone disconnects.
A 'sip show channels' reveals the following:
Peer User/ANR Call ID Seq (Tx/Rx) Format
[VoIP-provider] [ext. number dialed] 5b1fe97c04d 00103/00000 g729
[IP of Cisco phone] [ID of Cisco] 0002b9a7-4b 00102/00102 ulaw
2 active SIP channel(s)
Here g729 pops up, even though I have configured [VoIP-provider] to only
allow/use ulaw/alaw.
asterisk -vvv shows:
-- Executing Dial("SIP/[ID of Cisco]-4663",
"SIP/[VoIP-provider]/[ext. number dialed]") in new stack
-- Called [VoIP-provider]/[ext. number dialed]
-- SIP/[VoIP-provider]-77a8 is ringing
-- SIP/[VoIP-provider]-77a8 answered SIP/[ID of Cisco]-4663
-- Attempting native bridge of SIP/[ID of Cisco]-4663 and
SIP/[VoIP-provider]-77a8

I have in my sip.conf in the [general] section the following:
disallow=all
allow=ulaw
allow=alaw
and no allow/disallows at the phones themselves.
This used to work just fine... What could have happened...?
Regards,
Evert
