Hello,
I have the following scenario:
1 - Asterisk sends and invite to a SIP platform.
2 - The platform creates a second leg to make an outbound call.
3 - This outbound leg sends an Invite to Asterisk with the same CallID.
Asterisk replies with a 200OK. But when the sip platform replies with ACK Asterisk does not dial the number.
I have attached the SIP traces for this call. If anyone could please help me figure out the problem.
I am doubting two things:
1- Is there a param that i need to enable in sip.conf to support Invites with same CallID
2- The ACK for the second INVITE:
INVITE sip:102@192.168.0.114 SIP/2.0
ACK sip:5147658468@192.168.0.114 SIP/2.0
Is that normal??
[b]Asterisk is on IP 192.168.0.114
Sip Platform is on IP 192.168.0.112[/b]
Thanks.
