Hi, I have a customer who ha the following set-up:
SIP AS5350 VG with SIP trunk to SBC and ISDN Pri to the ISDN.
The problem they have is that their SP is expecting a 'user verified and passed' q931 message but the VG is sending 'user provided not screened'
They have asked if there is a way to change the config to give the correct the message/ modify the 3a octet?
Many thanks, John.
Info from the customer:
Please provide clarification on this point. SIP is common protocol where there are many CLI enhancements proposed in IETF forums. In Cisco VoIP Gateway, which parameter of SIP Header can be mapped to screening indicate in Q.931
Currently we are getting like below on Q931 setup
Calling Party Number i = 0x1180, '44750XXXXXXXX'
If we send on sip side as below
Remote-Party-ID: "0750XXXXXXXX " <sip:0750XXXXXXXX@10.22.1.38>;party=calling;screen=yes;privacy=full
Will it be on Q931 side as below ?
Calling Party Number i = 0x1181, '44750XXXXXXXX'
Please provide exact SIP Header which is mapped to Q.931 Screening Indicate to achieve as : Calling Party Number i = 0x1181, '44750XXXXXXXX'
Currently we are thinking, it is Remote-Party-Id. Please provide which SIP Header mapped to Screening Indicate with user provided and verified passed.
