[asterisk-users] Call Drops while doing assisted transfer from remote location

[das sandesh]

Hi all,

We have our system hosted publicly and 4 phones are connected remotely at
employee's home, and when they try to do a assisted transfer to one of the
employee at the main office, the call is lost. For ex: person A calls person
B, person B calls person C for assisted transfer, and as soon as person B
hits transfer button again to transfer person A to C, the call is lost.

But in the second senario, if the same call comes to the main office and if
they try to do an assisted transfer it works properly, but only from remote
office phones connected at their homes is not working as calls are lost. Can
anyone input some ideas on why it could happen, as even in the logs it
does'nt give much information...

We are using Yealink T28 phones. Asterisk version: 1.4.21.2, dahdi: 2.2.0.2

Thank you so much for your help.

Regards
Sandesh
