  • Shoretel to Asterisk Sip Trunk

    Ok I have read the other threads concerning this and have setup the trunk on the asterisk and ST boxes.

    I can call from the asterisk box to the ST box all day long, but I always get one way audio. I can hear on the ST but can't speak back to the Asterisk side.

    I also can't make any calls out through ST to the Asterisk box. It doesn't appear to me from the Asterisk side that Shoretel is even trying to communicate back to the Asterisk box.

    Does anyone have any ideas or some better setup instructions?

    I am trying to tie a Sphericall system to Shoretel and had a similar problem. I had to limit the codes on the Sphericall system to ulaw/alaw and not others. Try setting one codec at a time and figure out which one works and which ones don't.

    As for the calling from ST to Asterisk..make sure your Asterisk extensions are defined in your Off Site Extensions list for the trunk group going to Asterisk.

      Well I have it all worked out now. One question though, has anyone been able to get transfers working with ST side for calls originating from *. I can call in and hear any ivrs and can transfer to the initial extension but can't get it to allow us to transfer the call to any other extension.

        I wish I had something to offer other than "Me too." :wacko:

        I've been trying to figure out transfers from an incoming Asterisk PRI into our ShoreTel system since version 6 (we're currently on 7.5, about to make the jump to 9.1). Let me know if you have any breakthroughs.

          So did the jump to 9.1 make any difference? We haven't made that leap yet but are making plans to.

            Asterisk - Shoretel

            I believe Asterisk doesn't support the SIP Refer method in a fully SIP compliant way. When ShoreTel initiates the transfer/conference/Refer back with the Asterisk system, it will always fail. I don't think Asterisk has any plans to change that given the impact to their architecture. ShoreTel recommends the SIPerator appliance to correct vendor compatibility issues. I tried to use SER to get around this, but didn't try terribly hard.

              Asterisk and Shoretel

              I have found that the best way to handle this is to put an asterisk gateway onsite with a PRI pci card, and hand of the SIP to the shoretel as a PRI.. Have 4 deployed with multiple trunks into the system with full feature functionality and no issues.

                  hi Jrazal, you mean you deploy it as a PRI Tie trunk between the systems instead of just a sip trunk?
