Hi All.
Plz Help me on Below given scenario…
When a phone puts a call on hold, the Gateway sends an SIP INVITE message with an SDP indicating send-only. The softswitch should forward this re-invite to the other partner, where an ISDN phone can then show that the call is on-hold.
The asterisk currently does not seem to forward this.
Help me on asterisk configuration setting, where this forwarding of the re-invite is done correctly.
