[OpenSIPS-Users] Mediaproxy 2.1.0: dispatcher - relay problems

[Magnus Burman]

Glad my groggy brain could help. ;)

I did remove the from_tag, but inserted a new one. Reason for this was 
to get caller id to work. Been trying all kinds of PAI och 
Remote-Party-ID now, but nothing works. They tell me the E.164-number 
must be the user-part of the uri, ie sip:123456798 at domain.

In my route I rewrite the from_tag as late as possible, right before the 
t_relay(). Would mediaproxy be happier if I did this some other place, 
say at the very beginning of the routes?

It also boggles me that it says that "from_tag" not found... because 
it's clearly present. Would it say the same if it didn't understand the 
from_tag? If I remove mediaproxy (which I for my life don't want to do, 
much love your way for this product!), my calls are setup fine, 
caller-id is working and the rtp-data is sent correctly. So with my 
limited knowledge I don't understand why mediaproxy would object...

Again, thanks for a lovely product!
