Alcatel Unleashed

Hi,

I'm working with 4018 in SIP mode and i'd like to change the ptime oprion in G729 from 20 to 30 ms

Anyone knows how to made it?? Is it possible in txt config file or by telnet connection??

Regards

According to SIP version 2.12.13:
group sip
parameter g729_ptime=
Enum values codec Min Max Step
G729 10 80 10
codec Default
G729 20

Hi, thanks ,

But I've inclue option g729_ptime=30 in my txt file config but it does nos work.

This Phone is not registered to an OXE PBX.

Best regards

Post logs. The fact that doesn't register can be something else. The option you are modifying is for how much time lapse will be between rtp packets on G729. Don't break everything for a little problem

Hi,

Really i'd like to work with Iptpuch phones with 30 ms of inerval packetization to solve jitter and delays in the net.
I Know the phone supports 20, 30 and 40. But I don't know how configure it.
I'm using uploaded document to configure it, but there are no refences to codec parametrization.

Its old doc. Version 2.12.13 was introduced in year 2013. Take a look on TC1468ed07:
Edition 7 : 28 august 2013 Delivery for 2.12.13

2.1 Features delivered in 2.12.13
group sip
mptime_enable
0 =disable
1 =enable
Default value 0

and mentioned before ptime:

g711a_ptime=
g711u_ptime=
g723_ptime=
g729_ptime=

codec Min Max Step
G711a/u 5 80 5
G723 30 90 30
G729 10 80 10

thanks for all Oxe_4400,

I'm testing it and i'd like to know how to force in the SDP negotiation to mark the annexb=no.

do you know how??

Best regards

To set and insert in the "media attribute" field "annexb=no" in the SIP INVITE of OXO you have to uncheck the "Voice Active Detection" on VOIP PARAMETERS --> DSP.
