[asterisk-users] Asterisk to be used with Ciscs media gateways

[Mohit Saxena]

Hello Guys,

I have been trying to do this since 2 days but couldn't make it....need your help..
The scenario is as under:

PSTN-----Cisco AS5350-------Asterisk Box--------VoIP Providers


I am trying to use SIP on Cisco Gateways and Asterisk box for the connection. The configuration is as under:

Sip.comf

[PCCW-KPN]
type=peer
host=41.205.190.15
allow=ulaw
qualify=100
nat=no
canreinvite=no
user=07028000709


extension.conf
exten=07028XXXXXX,1,Dial(SIP/PCCW-KPN)

Cisco Gateway:
dial-peer voice 110 voip
 description Voip peer to test the server
 destination-pattern 1234
 session protocol sipv2
 session target ipv4:196.3.60.24
 session transport udp
 incoming called-number .T
 dtmf-relay rtp-nte
 codec g711ulaw
 fax-relay ecm disable
 fax rate 9600
 fax protocol t38 ls-redundancy 1 hs-redundancy 1 fallback pass-through g711ulaw
 clid strip




I am able to place call from cisco gateway to the asterisk box and also to some softphones extensions but when making a call from softphone from asterisk box to PSTN, it fails. While I debug on Cisco gateway I found that the To field is SIP header is coming as sip:41.205.190.15 which is not correct, instead it should be dialed number:41.205.190.15

Has any one of you tried using Asterisk in this scenario and also to do LCR and Quality based routing of International calls? Please let me know if there is any documentation /example of this kind available/
