I have a curious problem: on a new installation, I can register softphones, linksys, grandstream phones, but no yealinks. The yealink phones DO work on a local asterisk/freepbx and a different remote server that I tested them with, but when registration fails when they try to register on this PBX. installation details:
trunks and routes for in-and outbound traffic are working, the only thing I cannot get to work is the Yealink phones.
we are not using outbound proxy, and I have set display, username, authentication name all to the same value to make sure it is correct. the Codecs enabled on the phone are PCMU PCMA G722 and G729; on the server we have ulaw/alaw set.
Please let me know where I could start looking to fix this, because I am puzzled
Thanks
Tim
I just brought a grandstream phone (that was registering fine from the office it was connected in before) into the office wiht the Yealink phones, and it won’t connect either.
I am puzzled as to what it could be. From within this office, I can connect to other SIP providers, but not this server. It is connected via a USB 3G modem. as I said, I have 7 phones connected on that network to other SIP providers, so bandwith or NAT is not the problem…
any ideas anyone?
thanks I will check this out now. It seems as if they are correct, and I connect from other locations, but I do need to doublecheck things, as this asterisk is hosted on a virtual server - Maybe I should have mentioned this before, but I didn think of it before.
