Hello, Question about how LCR works: User1 sends a request for the PSTN to OpenSER. # 213.5.17.236:5060 -> 213.5.43.4:5060 INVITE sip:0030211687293@altecnet.gr SIP/2.0. OpenSER uses LCR and sends the request statefully to the PSTN gateway # 213.5.43.4:5060 -> 213.5.xxx.xxx:5060 INVITE sip:0030211687293@213.5.xxx.xxx:5060 SIP/2.0. Is it possible to maintain the domain info in the request that is sent to the gateway? I mean is it possible to send the request as follows: # 213.5.43.4:5060 -> 213.5.xxx.xxx:5060 INVITE sip:0030211687293@altecnet.gr:5060 SIP/2.0. Maybe I am wrong, but I think that this should be allowed. Thank you for any help. George Disclaimer The information in this e-mail and any attachments is confidential.
