asterisk users - Feb 2005 - Linksys PAP2 / RT31P2 + multiple G.729 calls

Hi,

anyone can confirm if the Linksys's ATA and Router (PAP2-NA and 
RT31P2-NA) have the same limitation of just one G.729 call like the 
Cisco ATA 186 ?

I'm testing both appliances here and found this issue but could not 
confirm this anywhere (nothing on the manual, no document or post from 
any user about this).

In my tests they use G.729 only on the first call and G.711 on the 
others. If I disable G.729 on sip.conf for both peers they can't 
establish a second call (ring but drop after answer). If there is 
allow=ulaw on sip.conf I can establish 1 G.729 call and 3 G.711 with 
RT31P2-NA (using three-way calling).

In PAP2-NA if I mark "Use Pref Codec Only" and there is one call 
established, when I call the PAP2 it replies with "488 Not Acceptable
Here".

Thanks,

     Leonardo

The Sipura SPA-2000 has that limitation, and the linksys ATA is based
on Sipura technology, so it would not surprise me if the PAP2's have
the same problem. Aparently, the Sipura SPA-2100 does not have this
limitation, when the most recent firmware update is applied to it,
however.

Holy Crap!!!!

I have just verified this! The linksys PAP2-NA will NOT SUPPORT 2
SIMULTANEOUS G729 CALLS!

And I just got off the phone with some super-level technician at linksys and
he said they knew this all along!!
What bastards!

Anyway, he told me they are comming out with the PAP2-NAv2 in a few months
which WILL allow 2 simul G729 calls.

eh..
they told me it was a CPU problem. that v1 of the pap2na didn't have the
horsepower to transcode 2 channels.
anyone know if the Sipura 2100 can do 2 simul 729 calls?

/Snip/

Horse Power?? Please elaborate. Is it a CPU issue or a power issue or
onboard Ram issue?
