Hello 

if someone can please help me 

I have 2 PBX  one is yeastar s300 and the other is cucm cisco

both PBX have the same dailplan 1XXX  

what i used is sip trunk to connect the PBXS

my problem is that when i call from from cucm to the s300 i get respone from yeastar that authorisation issue but the trunk is working with the outbound from s300 to cucm

mean the call is rejected from s300 

what i found if i changed the number in cucm 2XXX and call the s300 resive the calll with no problem

what i hope to find is how i can keep same dailplan same on both pbxs 

my configration is this:

CUCM:- outbound 

98.1XXX    (discard 98)----------> S300 (1xxx)

example:

98.1100 -----------> S300 (1100)

S300:- inbound

DID Pattern: 1000-1299

Extension Range :1000-1299

frimware is the latest for s300

that is all

thanks in advance

  Need more info. 

   

  Can you get a network capture from the S PBX while trying to dial a 1XXX extension from the CUCM and post?

  It seems that yeastar device regard the 1100 as the internal extension locally.

  You may change the DID number on S300:- inbound DID Pattern: 981000-981299

  And don't discard the 98 on cucm side.

  It will be interesting to see if Graham's suggestion works. 

  The setup that is initially described should work without issue as I have several setup in the same manner where the seen DID range is the same as the desired extension range and I have no issue (200-220). This is how it should work as it is indeed an extension matching process. I could not post a screen shot as the web page does not display enough of the screen to show both the DID range and extension range on the same without scrolling. 

  What we don't really know is what type of trunk (register or peer) is setup between the two systems and what parameters are set in the S PBX for the inbound on the trunk. It could be that the inbound parameters are looking at a different header for the DID and this may be why the S PBX will not process the call further as it can't match; hence why a capture is really needed.

  Thanks For the support its worked by sending 2 digit number from cucm to the s300 and only use sip-peer 

  before i  used sip -register with sip-peer one for outbound and one for inbound

   

  thanks with best regards
